Abstract :
In this paper, we show that the design of a UWB Butler matrix can be accomplished using couplers and phase shifters in microstrip/slot technology. As a result of the proposed approach, we present the design of a 4-element switched-beam array antenna operating between 3.1 and 10.6 GHz. An UWB switched-beam array antenna formed by four tapered slot antennas and a 4x4 Butler matrix has been presented.
