Design and Simulation of Wideband Monopole Microstrip Antenna

Abstract

The paper explicates an optimal antenna using a monopole with defective ground plane for wideband operation. The radiator is an etched square with square slots at the corners and is intended for radio communication. To realize wideband operation and to improve the gain of the antenna defected ground arrangement is utilized. Finite element method is used to analyze the presented design. This radiator can show maximum response at four different operating frequencies in the frequency range of 3X10³MHz to 9X10³ MHz and presents the gain of 9.06dB, 3.83dB, 3.48dB,4.40dB at 3.0X10³ MHz, 5.5X10³ MHz, 6.9X10³ MHz,9.1X10³ MHz respectively. The radiator which is designed in the current work is implemented for many uses like wireless broadband implementation applicable to stable wireless communications, WLAN, remote sensing/fixed metrological and satellite communications. The HFSS simulation tool is employed to simulate the developed antenna design.
