<p>A switched circular polarization phased-array antenna having a wide beam scan range comprises a first 180° phase shifter (12) connected with one branch of a branch circuit (14); a second 180° phase shifter (13) connected with another branch of the branch circuit; a radiating element (11) connected with the first and second phase shifters and adapted to radiate two linearly polarized waves orthogonal to each other; and control means (20) for switching the shifts of the first and second phase shifters from 180° to 0° and vice versa. The first phase shifter includes a delay line (12b).</p> |
