Abstract
A design for switchable beam linear arrays is described. The radiating element of the array is a balun-feed reconfigurable antenna and its exciting phase is controlled with two switched-line phase shifters. By switching the feed points, the reconfigurable antenna can generate dual radiations with the same amplitude and 180° phase differences. Moreover, the delay lines of the two switched-line phase shifters, respectively provide phase shifts of 45° and 90°. Therefore, the array elements can be excited with the progressive phases of {0°, ±45°, ±90°, ±135°}, and each progressive phase is corresponding to one radiation beam. A 1 × 8 array prototype operating in the range from 1.7 to 2.7 GHz is constructed. Experimental results for the performances of the phased array are shown.
