Analysis and Design of Dual-Band Frequency High Gain FSS Microstrip Antenna

Abstract

In this work, a frequency selective surface superstrat dual-band microstrip antenna is proposed. In order to enhance the antenna's gain, the FSS layer is obtained via a periodic arrangement of 5x8 unit motifs in the x-y axis. The FSS layer acts as a reflection surface on the patch, increasing the antenna's gain at higher frequencies. The rectangular patch with a slot and full ground plane is used to create the dual-band antenna.Ours results indicate that the proposed design improves gain and directivity, and it could be used for high gain and wideband systems in the 5G applications.
