摘要：

A 1-bit phase reconfigurable fixed-frequency beam steering leaky-wave antenna (FBSLWA) with wide-angle steering is proposed in this paper. By controlling two p-i-n diodes on the branches of the element, a stable 180 degrees phase difference is realized. Moreover, the open stop-band effect at the broadside radiation is suppressed by reducing the reflection coefficients of the element. The proposed FBSLWA can achieve wide-angle steering within a frequency bandwidth of 10.4 GHz-11.8 GHz. As for the measured results, they show that the achievable beam steering ranges of the FBSLWA at 10.4 GHz, 11.0 GHz, and 11.8 GHz are -61 degrees to +59 degrees, -64 degrees to +71 degrees, and -62 degrees to +58 degrees respectively, with measured peak gains of 12.1 dBi, 13.9 dBi, and 11.7 dBi.
