Design and Analysis of a New G-Shape Single Layer Reflectarray Antenna

Abstract

In this paper, a new design single layer rectangular patch microstrip reflectarray antenna (MRAA) with G-shape slot has been suggested for satellite communication. A 6 GHz, C-band resonance frequency is targeted in this work. Each shape is constructed using the proposed elements with variable dimensions. The selection of shapes-pattern is based on the beam-shaping of the antenna. 3-dB gain bandwidth of 32.21 dB and linear phase range 326° has been obtained for this design. Maximum reflection efficiency 97.49%. Suitable results have been acquired from simulated work for the application frequency band, which is approved by the manufactured antenna. Despite the small size of the antenna, it has acceptable results compared with the traditional parabolic antenna. Horn antenna is used to feed the reflectarray antenna. The purpose of the antenna design to obtain a wide reflection phase, lower reflection losses and high gain.
