  • Abstract
    The focusing property of a bow-tie antenna coupled catadioptric lens is studied experimentally using a vector measurement setup. The results show that the lens-antenna provides short-range focusing. Furthermore, the return loss of the lens-antenna was determined numerically and confirmed experimentally from 1 to 10 GHz. The lens-antenna provides 60% bandwidth (VSWR ?? 2) centered at 6 GHz. Finally, the lens-antenna was employed to detect and locate buried objects, and results are presented.
