Design and Analysis of a Wideband, High Gain, and Low SLL Phased Reflectarray

This manuscript presents a lightweight, wideband, and high gain phased reflectarray design in the X band frequency range. The proposed work considers a unit cell structure consisting of a square patch with a centered square slot. It gives a reflection magnitude of − 0.7 dB and a phase tuning of 320°(−180° to 140°) for the frequency range of 9 – 11 GHz. The phased reflectarray is designed and simulated. The gain of reflectarray is around 23.6 dB in the center frequency of 10 GHz and the gain is more than 22 dB in the frequency of 9-11 GHz.
