Simulated design and analysis of a simple tri-band microstrip antenna is presented in this paper. A thin transmission line is used to excite the rectangular patch and FR4 epoxy with relative permittivity of 4.4 is used as substrate. To confirm the proficiency of proposed antenna, simulations have been performed in Ansoft HFSS (High Frequency Structure Simulator) a 3D electromagnetic field simulator, based on finite element method. Impedance bandwidths are determined on -10 dB at resonating frequencies of 2.4, 3.3 and 5.3 GHz. An introduced design covers the requisite bandwidth for IEEE Wireless Local Area Network (WLAN) standards: 802.11 a/n, b/g (Wi-Fi), Bluetooth, ZigBee, and 802.16e (WiMAX). Multiband functionality, small size, light weightiness, plain configuration and conformability are the advantages; making the proposed design a good contender for integration in handheld wireless devices.
