A new FSS superstrate structure for antenna performance enhancement

摘要

A high gain resonant cavity antenna using a new Frequency Selective Surface (FSS) superstrate is presented. In the proposed design, the simple superstrate is composed of two different dielectric slabs with different material proprieties and thicknesses, both are arranged to be highly reflective to achieve gain and directivity enhancement. Furthermore, the Software CST Microwave Studio is used to extract the directivity and the radiation pattern of the FSS resonator design. The proposed antenna using a single probe feeds is designed to operate at 5.8-6.2 GHz region. The measurement results are included for supporting the modelings and simulations.
