Abstract :
In this paper, a new fixed-frequency beam-steerable reconfigurable leaky-wave antenna concept is developed. The concept is based on the usage of a semiconductor substrate for creating surface p-i-n devices, which are utilized to switch between the different aperture configurations. A 35° main-beam scan range is achieved at a constant frequency f = 7.9 GHz by fourfold switching.
