Abstract (en)
[origin: WO0059071A1] An antenna system comprises an antenna element (42; 104; 204) and at least one feed unit (44, 46, 50, 52; 92, 94; 192, 194; 142, 144) coupled to the antenna element so as to allow passage of a signal therebetween, wherein the system includes delay means for introducing a phase delay into a component of said signal to remove quadrant ambiguity in signals received by the antenna element or to allow phase/amplitude control of a signal transmitted by the antenna unit.
