Abstract

The switched-beam antenna of the free space was discussed by the use of radial guide with coaxial probes and a dielectric transition. It was observed that a top ground plane with a guide to free space transition was used in order to add a new degree of freedom in the antenna. It was also observed that the radiation pattern gain was decreased and the radiation beam squint off the ground plane was increased with the increased dielectric permittivity. The guide to-free-space transition with a large enough Tl= 60mm, 0>0°(10°) and low dielectric permittivity (ε=2) was used to achieve a radiation pattern with a good gain and return loss bandwidth.
