Wideband MSA for Dual Band Operation using Slot Loaded Finite Ground

Abstract

This work proposes a modified square compact microstrip patch antenna with a slot-loaded finite ground plane for dual band operation. By making a corner cut and inserting slits within the margins of the radiating patch with a slot-loaded finite ground plane, a dual band modified square microstrip patch antenna with wideband is produced. Two operational frequencies of 3.21 and 4.03 GHz are shown to be achievable. with these operating frequencies, the obtained impedance bandwidths with 10 dB return loss are 15.58% (500 MHz) and 27.8% (1120 MHz), respectively. This antenna's high bandwidth, dual band operation, and compact size make it suitable for many wireless communication systems.
