High Gain High Dense Dielectric Patch Antenna Using FSS Superstrate for Millimeter-Wave Applications

Abstract

High gain low profile linearly polarized square dense dielectric (DD) patch antenna using a frequency selective surface (FSS) superstrate layer is proposed. The implemented antenna is designed, and excited by aperture coupled feeding technique. The DD patch is used as a radiated element. An array of frequency selective surface FSS is used to enhance the gain of the antenna. The antenna gain is enhanced by 10 dBi. The implemented antenna obtained a gain of about 17.78 dBi at 28 GHz with radiation efficiency of 90 %. Furthermore, it has a bandwidth of about 9 %. It has a good radiation performance. For some attractive advantages such as low profile, low cost, light weight, small size, and ease of implementation, the proposed antenna is a good candidate for millimeter wave wireless communications.
