Design and analysis of a compact microstrip antenna using shorting pin for 5 GHz band

Abstract

A compact microstrip patch antenna (RMPA) using shorting pin is based on the introducing rectangular slot in the ground plane is proposed for useful current miniaturized wireless communication system and designed in this paper. This modified antenna to have characteristics of wideband operation, enhance bandwidth, along with reducing the size and improved gain. A meandered probe-fed rectangular shaped slot coupled with horizontal slots on a ground layer with a dimension of 18 × 21 × 1.6 mm3 having dielectric material substrate (εr=4.4). The main purpose of this work is to propose a wideband and improved gain antenna for mobile WiMAX, Wi-Fi/WLAN as well as military applications. The simulated results show that, the proposed antenna has achieved wider bandwidth with satisfactory gain by introducing probe fed with shorting pin in the assistant of partial ground plane.
