Definitions
- the field of the invention is that of microwave antennas. More specifically, the invention relates to a bi-polarized printed antenna, as well as a corresponding antenna array.
- the antenna according to the present invention has many applications. She can by example be used as a probe in antenna test devices by measuring radio radiation. It will be recalled that such devices allow in particular perform radio coverage forecasts, device measurements (mobile or other) for compliance with standards, a verification of the securing the useful signals emitted, or measures intended for the study of interactions of radio waves with people.
- GSM radiocommunication system
- multimedia satellite receiver it can also be used in the telecommunications sector, for example example in the base stations of a radiocommunication system (GSM or other), or in a multimedia satellite receiver.
- GSM radiocommunication system
- the antenna used has an omnidirectional radiation pattern (closest to one infinitesimal dipole), wide bandwidth and excellent polarization purity.
- the antenna is at double polarization. Indeed, there is a generalization of the use of this type of antenna polarized duplex.
- an antenna test device now requires the use of polarized duplex probes, that is to say capable of measuring two orthogonal components of the electric field. Indeed, the measurement made by the test device must in particular provide, for the antenna under test, the polarization decoupling characteristics. We therefore understand that the probe itself must have excellent insulation between its accesses and present levels very low cross polarization.
- type antennas are used as measurement probes open guide or cornet. However, these have a significant "thickness" (5 to 10 wavelengths ⁇ ) which becomes prohibitive for use in bands of frequencies below 3 GHz.
- the invention particularly aims to overcome these various drawbacks of the state of the art.
- one of the objectives of the present invention is to provide a bi-polarized printed antenna having not only a diagram of omnidirectional radiation and excellent polarization purity, but also a large bandwidth (for example greater than 50% at ROS ⁇ 2).
- the invention also aims to provide such an antenna which can operate in circular polarization.
- Another object of the invention is to provide such an antenna having a increased directivity.
- the general principle of the invention therefore consists in superimposing at least one first dipole printed in T and at least one second dipole printed in T, each having a distinct polarization.
- the bi-polarization antenna according to the invention benefits from all the advantages of the dipole printed in T "monopolarization”, namely a low size, easy mechanical maintenance, radiation diagram omnidirectional and wide bandwidth (greater than 50% at ROS ⁇ 2). Furthermore, it it is a simple technology to implement.
- the small footprint of the antenna according to the invention makes it particularly suitable for the aforementioned test devices, and in particular to those in the near field.
- these allow you to measure the radio field emitted at a short distance by electronic equipment (under test).
- Such measures aim to provide better knowledge of phenomena of short distance propagation of electronic devices, and to allow highlighting the interactions between the waves radiated by the devices and the human body (which is often made difficult by the extreme proximity of the device).
- said first deposit metallic defines two first radiating elements of the dipole type, each in shape of T and joined to each other by the free end of the vertical bar of each T.
- Said first supply line has two branches each supplying one of the two first radiant elements.
- Said second metallic deposit defines two seconds radiating elements of the dipole type, each in the shape of a T and joined to one another by the free end of the vertical bar of each T.
- Said second supply line has two branches each supplying one of the two second radiating elements.
- the longitudinal axis of the T of said first radiating elements is offset by approximately 90 ° relative to the longitudinal axis of the T of said second elements radiant.
- the vertical bar of the T of each radiating element constitutes a ground plan for at least part of said first and second lines feed.
- the vertical bars of the T of the first elements therefore constitute a first ground plane
- the vertical bars of the T of the second elements therefore constitute a second ground plane.
- the power lines are working like triplate elements (striplines), and are therefore shielded (they are included between the first and second ground planes). This eliminates leakage and parasitic diffractions, which would be likely to deteriorate the performances (in polarization purity) of the overall structure.
- the invention also relates to a dual-band, double-printed antenna polarization in each band.
- the invention also provides for the networking of the antenna described above, of so as to obtain an increased directivity.
- the invention therefore relates to a bi-polarized printed antenna.
- polarizations ⁇ 45 ° for example polarizations ⁇ 45 ° for example.
- the first supply line 7 has a first access (denoted “access V”, for vertical access, in figure 1).
- the second supply line 11 has a second access (noted “access H”, for horizontal access, in Figure 1).
- Each of the accesses H, V of the supply lines 7, 11 is for example connected to a SMA (or other) type connector (not shown) itself connected to a coaxial cable.
- the longitudinal axis of the T of the first radiating elements 5,6 is offset about 90 ° relative to the longitudinal axis of the T of the second radiating elements 9, 10.
- the first and second metallic deposits 4, 8 have in this example the same shape (including the square conductive central surface discussed below), and are simply shifted a quarter turn from each other.
- the vertical bars of the T of the first radiating elements 5, 6 constitute a first ground plane for the first and second supply lines 7, 11 (and in particular for the divider by 2 included in each of these latter).
- vertical bars of the Ts of the second radiating elements 9, 10 constitute a second ground plane for the first and second supply lines 7, 11 (in particular for the divider by 2 included in each of these).
- the first and second supply lines therefore function as triplate elements (stripline).
- the free end of each of these vertical bars of T is widened, so that increase the surface of the ground planes. In the example illustrated, enlargement is translated by obtaining, at the center of each of the first and second metallic deposits 4, 8, a conductive surface of square shape.
- Each of the branches 7a, 7b, 11a, 11b of the supply line has a first end portion extending along an axis intercepting the axis of the slot of one radiating elements and protruding from the axis of the slot of one of the radiating elements a first variable adaptation length (or series stub) 11. Furthermore, the slot of each of the radiating elements has a second end portion projecting from the axis of the first end portion of a second variable adaptation length (or parallel stub) 12.
- the first and second lengths adaptation 11, 12 are referenced, in FIG. 1, only for one of the branches power supply (the one referenced 7b). A suitable choice of these series and parallel stubs 11, 12 makes it possible to adapt the radiating element concerned over a wide band.
- the antenna can also include means with variable capacity (not shown), allowing to act electrically on the first and second lengths adaptation variables (series and parallel stubs) of each of the radiating elements.
- variable capacity allowing to act electrically on the first and second lengths adaptation variables (series and parallel stubs) of each of the radiating elements.
- this electrical action has the same effect as an elongation or a decrease physical (that is to say real) of the stub on which we act. Examples of such means to variable capacity are described in detail in French patent n ° 93 14276, to which can refer.
- This antenna is extremely wide band since it operates from 0.6 GHz to 1.1 GHz for an ROS less than 2 (see fig. 3). This corresponds to more than 75% of the band busy. Remember that this percentage is obtained by dividing the bandwidth by the center frequency of this band.
- Its impedance curve shows a characteristic coupling loop of the dipole element, the latter being associated on the one hand with its series stub (line which goes beyond the coupling slot) and on the other hand to its parallel stub (slit which extends beyond the supply line). It is the presence of this loop which guarantees low frequency dispersion and reflects the efficiency of the device feed.
- the antenna according to the invention also makes it possible to generate in a simple and efficient circular polarization, by supplying the pairs of prime 5, 6 and seconds 9, 10 radiating elements in quadrature. In other words, we introduce between these two couples a phase shift of ⁇ / 2 in time.
- the antenna includes in addition to phase shifting means.
- a first solution (cf. fig. 8) consists in using a hybrid element 80.
- This well-known hybrid element comprises two input terminals 81, 82 and two connection terminals output 83, 84.
- one injects on one of the input terminal if the antenna works in transmission), or we receive there (if the antenna works in reception), either a signal in right circular polarization (for example on the input terminal 81), or a signal in left circular polarization (for example on the input terminal 82).
- the output terminals 83, 84 are connected respectively to the H and V ports of the first and second supply lines 7, 11.
- a second solution (cf. fig. 9) consists in using a rat-race 90 ring.
- rat-race ring also well known, also includes two input terminals 91, 92 and two output terminals 93, 94. Its implementation, within the framework of the present application, is identical to that described above for the hybrid element 80.
- a third, more compact solution (see fig. 10) consists in using localized elements (chokes and capacities).
- the corresponding assembly (well known in itself) 100 also includes two input terminals 101, 102 and two output terminals 103, 104. Its implementation, in the context of this application, is identical to that described above for the hybrid element 80.
- phase shifting means can be integrated on a printed circuit coming to be placed in the middle of the superimposed structure.
- the second substrate plate 2 (or plate central) is divided into two sublayers 2A and 2B, between which comes position the printed circuit (or metallic deposit) 12 supporting the means of phase shift.
- This printed circuit 12 is connected on the one hand to the access V of the first line supply 7, via a first metallized hole (or through contact) 13, and on the other hand to the access H of the second supply line 11, via a second metallized hole 14.
- the antenna may include means for reflection, aimed at increasing its directivity by removing part of its radiation. This involves, for example, removing rear radiation from the antenna, so as to direct the radiated energy forward and increase the directivity of the antenna a few dB, while maintaining broadband performance.
- a first solution (cf. fig. 12) consists in introducing the antenna 120 (such as previously described) in a waveguide section 121. This makes it possible to constitute simply a duplex waveguide supply system.
- a second solution (see fig. 13) consists in using a ground plane 131 at approximately ⁇ / 3 of the antenna 130 (as previously described). Note that the diagrams of radiation presented in Figures 6 and 7 were obtained in the presence of a plane of ground.
- the antenna in order to increase obtaining an increased directivity, to network the antenna as described above.
- the antenna then constitutes the basic element of the network.
- the network is one-dimensional. It presents a diagram of directional radiation in elevation (as schematized by the circular arc referenced 140) and wide (even omnidirectional) in azimuth (as shown schematically by the circular arc referenced 141).
- a network with such qualities is suitable in particular to the antennas of the base stations of the radiocommunication systems (for example GSM or DCS example).
- the network is planar two-dimensional. It allows large pointing up to low elevations, thanks to its elementary diagram less directive than that of the resonant printed elements traditional (with patches).
- a network with such qualities is suitable for ground antennas, intended for reception in multimedia satellite applications.
- networking can be combined with the use of means of reflection (for example a ground plane).
- the dimensions of the third and fourth metal deposits 24, 26, which are found at the ends of the overlay, must be less than those of the first and second metallic deposits 4, 8. In other words, the second frequency band must be higher in frequency than the first.
