Abstract
The present description concerns an antenna system comprising a transmitting or receiving antenna element (12), an array of parasitic antenna elements (14), individually associated with reconfigurable loads (15), one or a plurality of near-field antennas (32), and a circuit (18, 34) for setting the configuration of the array of parasitic antenna elements according to a radiation picked up by the near-field antenna(s) during a radio frequency transmission by the transmitting or receiving antenna element.
Claims8
Antenna system comprising:
- a transmitting or receiving antenna element;
- an array of parasitic antenna elements individually associated with reconfigurable loads;
- a plurality of near-field antennas;
- and
- a circuit for setting the configuration of the array of parasitic antenna elements according to a radiation picked up by the near-field antennas during a radio frequency transmission by the transmitting or receiving antenna element,
- wherein the circuit is configured to adjust impedance values of the reconfigurable loads according to a comparison, with reference data representative of radiation patterns of the system in the presence of interferences, of data representative of a radiation pattern of the system,
- and wherein each near-field antenna is coupled to an electronic circuit for assessing near-field radiation.
