Abstract (en)
[origin: FR2828583A1] The closure process for an electronic sweep antenna has radiating elements in front of a high frequency phase shifter. The phase shift cell has switches (21,22,23,24) in cascade. Each rear cells (241,242) carries a radiating element and switches (D9,D10). Antenna closure is obtained by controlling the switches in the pass state.
