Definitions

  • This description relates generally to electronic devices, more particularly to reconfigurable antennas.
  • reflector antennas have been proposed in particular.
  • these antennas are complex and expensive to produce because reflectors require, especially for high-frequency applications, a very precise curvature.
  • motors are used to steer the beam in the desired direction.
  • Phased array antennas have been proposed to allow electronic beam control.
  • these antennas are expensive to develop and produce, particularly because they include amplification modules to compensate for losses induced by phase-shift circuits.
  • each elementary cell is capable of compensating for each path difference between the focal source(s) and the radiating aperture.
  • the elementary cells can only compensate for a limited number of phase states, for example 2 N phase states, with N a positive integer, in the case of N-bit phase quantization compensation.
  • the same transmitter network can alternate between transmission and reception phases, provided that it is devoid of non-reciprocal elements such as amplifiers or attenuators. Otherwise, the transmitter network can only operate in transmission or reception.
  • Transmitting array antennas suffer from various drawbacks.
  • existing transmitting array antennas have a relatively large thickness, imposed by a need to distance the focal source(s) from the transmitting array.
  • said at least one source is connected to a radiofrequency signal transmission/reception circuit.
  • the antenna comprises fewer first elementary cells than second elementary cells, preferably four times fewer first elementary cells than second elementary cells.
  • FIG. 1 is a schematic and partial side view of a reconfigurable antenna 100 according to one embodiment.
  • the elementary cells 103 of the amplifier network 101 are connected to a circuit 109.
  • the circuit 109 is for example a circuit for transmitting/receiving radiofrequency signals, for example a circuit intended to produce signals to be transmitted by the reconfigurable antenna 100 and/or to process signals received by the reconfigurable antenna 100.
  • This example is however not limiting, the circuit 109 being able to further implement additional functions such as analog-digital conversion, filtering, impedance matching, interference elimination functions, etc.
  • the elementary cells 103 are connected to the circuit 109 by conductive tracks and/or conductive vias of the printed circuit board in and on which the amplifier network 101 is produced.
  • each elementary cell 103 of the amplifier network 101 is capable of receiving a signal coming from the circuit 109 and of emitting electromagnetic radiation, corresponding to the received signal, from its antenna elements 103b towards the transmitter network 105.
  • Each elementary cell 107 of the transmitter network 105 is capable of receiving, on its first antenna element 107a, the electromagnetic radiation emitted by the elementary cells 103 of the amplifier network 101 and of re-emitting this radiation from its second antenna element 107b, for example by introducing a known phase shift ⁇ .
  • the elementary cell 103 comprises an amplification circuit 200 comprising a switch 201, for example a single-pole double-throw (SPDT) switch.
  • the switch 201 more precisely comprises an input connected to the circuit 109, a first output connected to an input of a first amplifier 203 (PA) of the amplification circuit 200, and a second output connected to an output of a second amplifier 205 (LNA) of the amplification circuit 200.
  • the switch 201 receives, for example, a control signal to connect its input to its first output, when the reconfigurable antenna 100 is used in transmission, and to its second output, when the reconfigurable antenna 100 is used in reception.
  • each amplification circuit 200 is located substantially directly above the center of a square formed by the four antenna elements 103b of the corresponding elementary cell 103.
  • each amplification circuit 200 is connected to the circuit 109 by radiofrequency lines 301, symbolized by strong line segments in Figure 3 .
  • power dividers may be provided at the intersections between the radio frequency lines 301 in order to divide the power of the signal transmitted from the circuit 109 to the circuits 200.
  • the amplifier circuits 200 and the antenna elements 103b have been symbolized, in Figure 3 , by squares, it being understood that the amplification circuits 200 and the antenna elements 103b can, in practice, have any shape.
  • the reconfigurable antenna 100 previously described in connection with the figures 1 to 3 has for example a hybrid structure between that of a phased array antenna and that of a transmitting array antenna.
  • the antenna 100 differs from a phased array antenna in that the amplifier network 101 is devoid of phase shift circuits. This advantageously makes it possible to avoid energy losses and to eliminate tedious steps of synchronization and calibration of radiofrequency lines making it possible to connect, or connect, each elementary antenna of the phased array to a control circuit, for example analogous to the circuit 109.
  • the phase shifts are applied by the transmitter network 105, for example using radio frequency switches.
  • the operation of the reconfigurable antenna 400 in particular the control of the switch 201 of each elementary cell 403 depending on whether the antenna 400 is used for transmission or reception, is analogous to the operation previously described in relation to the Figure 2 for the reconfigurable antenna 100.
  • the reconfigurable antenna 400 has advantages similar to those of the reconfigurable antenna 100.
  • the elementary cells 107 of the transmitter network 105 can be calibrated in order to correct phase errors linked to the structure of the antenna.
