Performance of patch antenna through varying structure and positions

Abstract

A miniaturized 15×20×1.6 mm3 antenna has been proposed with improved impedance bandwidth and gains for wireless communication applications. The proposed antenna has been attached with three narrow rectangular stubs; in addition, the bottom plane of the antenna has been inserted with –ε, -µ structure. The antenna properties like radiation pattern, gain, field distributions have been mentioned. Moreover, the proposed metamaterial has been optimized to get better characteristics by using HFSS 2020R1. Here, we have observed the effect of the resonance frequency of the designed antenna by changing the position of the metamaterial in the ground plane. The aforesaid antenna covers the wireless, Wi-MAX, C Band, K Band, Ku Bands with significant gain, S11 < -10dB. The antenna has been fabricated and tested.
