Definitions

  • the invention relates to an antenna device and in particular to an antenna device having at least a first antenna in the form of a flat antenna and at least a second antenna in the form of a three-dimensional antenna.
  • a patch antenna is a directional flat antenna that radiates the majority of its energy in a vertical direction.
  • a well-known patch antenna is, for example, Figure 1A shown.
  • Figure 1B shows the corresponding directional characteristic, where it can be seen that little to no radiation is emitted in the horizontal plane (represented by points A and B). For this reason, communication in this plane is very difficult or even impossible.
  • FIG. 1C An antenna arrangement 5 known from the prior art is shown. This antenna arrangement 5 has four individual flat antennas 1, 2, 3, 4, which are arranged symmetrically around a power distribution unit 6.
  • EP 0 163 454 A2 discloses an antenna device comprising at least a first antenna, a flat antenna parallel to and above the ground plane on the surface of the substrate, and at least one second antenna on a substrate, which are connected in series with each other, wherein the flat antenna has a main lobe extending substantially vertically upwards and the second antenna has a main lobe extending substantially in the horizontal plane.
  • EP 1 845 586 A1 discloses an antenna device having at least a first antenna, a flat antenna on the surface of the substrate, and at least one second antenna on a substrate, which are galvanically connected to one another at a common signal feed section, wherein the flat antenna has a main lobe which extends substantially vertically upwards and the second antenna has a main lobe which extends substantially in the horizontal plane, wherein a metallization is arranged at least in sections on the second substrate side.
  • DE 201 06 005 U1 discloses an antenna device having at least one first antenna, a flat antenna parallel to and above the ground plane on the surface of the substrate, and at least one second antenna, which are galvanically connected to one another at a common signal feed section, wherein the flat antenna has a main lobe which extends substantially vertically upwards and the second antenna has a main lobe which extends substantially in the horizontal plane.
  • At least one second antenna is additionally arranged on the first main side of the substrate.
  • This second antenna can be a three-dimensional antenna that extends primarily three-dimensionally in space, i.e., in comparison to the flat antenna, in at least one further spatial direction, for example in a z-direction.
  • the antenna device 10 according to the invention is also referred to below as an Ndip antenna in reference to the inventor, Dr. Ivan Ndip.

  • the flat antenna 14 has a geometric length L which is Figures 2A and 2B is identified by the reference numeral 21. Orthogonal to the current flow direction or to a main extension direction 21 of the flat antenna 14, various positions 22, 23, 24 are shown, at which the geometric length L of the flat antenna is indicated as a function of the wavelength ⁇ of the fed-in signal.
  • the second antenna 13 has a first vertical spacing 26, ie orthogonal to the substrate plane 15, from the first main side 11A of the substrate 11 approximately in the middle. Since the second antenna 13, as mentioned at the beginning, is stretched in an arc shape over the flat antenna 14, the second antenna 13 has a second vertical spacing 25 and a third vertical spacing 27 to the left and right of its center.
  • the second antenna 13 can have the greatest vertical spacing 26 from the flat antenna 14 at precisely this location.
  • At least the flat antenna 14 or at least the second antenna 13 can be galvanically or capacitively coupled to the metallization 12 on the second main side 11B of the substrate 11.
  • either the flat antenna 14 or the second antenna 13 can be coupled to the metallization 12, or both the flat antenna 14 and the second antenna 13 can be coupled to the metallization 12.
  • the coupling can be, for example, a capacitive coupling, as in Figure 2C

  • Figure 3 shows an approximate schematic representation of the current flow or the current density distribution along an antenna 13, 14 over its geometric length L as a function of the wavelength ⁇ of a common radio signal. The diagram represents the signal flow at the two Figure 2A shown antennas 13, 14, whereby both antennas 13, 14 are fed with the same signal.
  • Curve 31 represents an approximate current profile in the second antenna 13.
  • Curve 32 represents an approximate current profile in the flat antenna 14.
  • the second antenna 13 Since the second antenna 13 is short-circuited or terminated, its current flow 31 is proportional to the magnitude of the cosine function cos 2 ⁇ L 3 D ⁇ , where L 3D is the geometric length of the second antenna 13 plotted on the x-axis as a function of the wavelength ⁇ .
  • the second antenna 13 and the flat antenna 14 are combined in such a way that coupling between the two antennas 13, 14 is minimal at those points where they each have their maximum field strength values. This then results in constructive interference, as in Figure 3 is shown.
  • the second antenna 13 shown and the flat antenna 14 can be two resonant antennas. This means that the flat antenna 14 is tuned to a first resonant frequency and the second antenna 13 is tuned to a second Resonance frequency tuned.
  • the two resonance frequencies are preferably the same.
  • the first and second resonant frequencies differ from each other by 5% or more. According to one conceivable embodiment, the first and second resonant frequencies simultaneously differ from each other by less than 30%. This allows the NDIP antenna to achieve a broadband performance, i.e., the greater the deviation between the first and second resonant frequencies, the wider the achievable broadband spectrum. A multiband NDIP antenna, so to speak, can be realized.
  • the two antennas 13, 14 therefore influence each other as little as possible, so that the Figure 3 shown signal curve with a phase shift of 90°, or in other words, when the radiation coupling of the two antennas 13, 14 is minimal where one of the two antennas 13, 14 has its power maximum.
  • the combination of the radiation characteristics of both antennas 13, 14 to form an overall radiation characteristic of the Ndip antenna 10 according to the invention is particularly advantageous.

  • Curve 44 represents the radiation characteristic of the flat antenna 14
  • curve 45 represents the radiation characteristic of the second antenna 13
  • curve 46 represents the radiation characteristic of the inventive Ndip antenna 10.

  • the second fastening region 17 or the first attachment section 13A of the second antenna 13, which is not arranged on the common signal feed section 16, can be arranged at any location, i.e. 360° around the flat antenna 14, on the substrate 11.
  • Figure 5C shows an example not belonging to the invention with a flat antenna 14 arranged on a substrate 11 and a second antenna 13 arranged on the substrate 11.
  • a first end 13A or a first attachment section 13A of the second antenna 13 is still arranged on the fastening area 17.
  • the second end 13B or the second attachment section 13B is arranged on the flat antenna 14 and can be mechanically and optionally galvanically coupled to the flat antenna 14.

  • the maximum value of the current on the second antenna 13 is approximately where the minimum value of the current of the patch antenna 14 is, as in Figure 3
  • the Ndip antenna 10 according to the invention radiates very well both in the horizontal (azimuthal) plane and in the vertical (elevation) plane, as shown in Figure 4C is shown.

  • the number and position of the second antenna 13 can be varied to change the radiation pattern of the Ndip antenna 10.
  • This radiation pattern can also be adjustable, e.g., depending on whether the flat antenna 14 is arranged at the beginning or end of the second antenna 13.
  • Two or more Ndip antennas 10, 70 which may be arranged on a common substrate 11, may also be combined to form an antenna array 100.
  • the inventive Ndip antenna 10 can also be designed to have a very high bandwidth compared to conventional antennas.
  • the second antenna 13 and the flat antenna 14 can be optimized such that their resonant frequencies overlap. The resulting bandwidth will thus be significantly larger than that of conventional antennas.

  • the inventive Ndip antenna 10 Since at least one of the two antennas 13, 14 of the inventive Ndip antenna 10 is always vertically spaced or "suspended" from the dielectric substrate 11, most of the losses associated with dielectrics (e.g., losses due to surface waves, dielectric conductivity, and loss factor) are minimized. For this reason, a significantly higher radiation efficiency can be achieved with the inventive Ndip antenna 10.
  • a reconfigurable Ndip antenna 10 can be realized, for example, by placing a switch between the second antenna 13 and the flat antenna 14. For example, if a switch is placed on the common signal feed section 16 ( Figure 2 ), the current flow to the second antenna 13 and to the flat antenna 14 can be controlled. By controlling the current flow of the individual antennas 13, 14, the radiation pattern of the Ndip antenna 10 can also be controlled.
