A rhombus shaped metamaterial inspired antenna in the ground plane for X band applications

Abstract

The objective of this paper is to present the dual band antennas that are going to work at a different set of frequencies. By using slots and rings in ground plane and top of the patch we designed dual-band antenna, works at two different set of frequencies (15.2 GHz & 23.42 GHz) with high gain which mainly covers the applications of microwave frequency Ku-band and K-band. There after we proposed metamaterial inspired antenna at X band range (25 mm to 37.5 cm).The needed-10 dB S11 of the antenna is obtained by analytical modeling and simulation with the help of both versions of HFSS 13.0.
