Device for transmitting and receiving microwaves subjected to circular polarization

摘要

The invention relates to a device for transmitting and receiving microwaves including a planar radiating element. The device is characterized in that the radiating element (60) has substantially orthogonal transmit and receive ports (68, 66) and the relative phase of the transmit and receive signals and the shape of the radiating element are such that the transmit and receive signals, whose frequencies are different, are circularly polarized in opposite directions.
