Description
Summary:This document proposes a novel quad-band microstrip antenna. The proposed antenna primarily comprises of a horizontal H-shaped patch, an L-shaped open end stub, and a deformed inverted T-shaped strip with an isosceles triangular shape attached to it. The antenna resonates at four frequencies, 2.75 GHz, 3.34 GHz, 5.49 GHz and 6.65 GHz which makes it susceptible to use in WiFi, WiMAX, WLAN, Satellite communications etc. The miniature size of 30×20×0.8 mm 3 has also made this antenna superior than other available larger antenna. CST Microwave studio has been used to evaluate the performance of this proposed antenna. The return loss, efficiency, gain, radiation pattern, surface current and VSWR has also been analyzed here. Simulation results also show that this antenna has highly directive radiation characteristics and stable gain across all the frequency band. The range of VSWR from 1 to 2 indicates well impedance matching with the feeding transmission line of the designed antenna.
