A compact pattern reconfigurable antenna employing shorted quarterwave patch antennas

In this study, a compact pattern reconfigurable antenna structure is proposed. The proposed half-wave square microstrip patch divided into two quarter-wave portions by conducting wall. This wall forces potential zero at the connection point; therefore, it separates independent portions. Pattern reconfiguration achieved separate feeding of Phase difference between excitations ports result in variation maximum beam direction. Hence, achieved. Within such antenna, steering up to 400
