Abstract

This paper presents the design of rectangular microstrip slot loop antenna that competently achieves dual frequency operation by using a microstrip feed line. This antenna is designed at the resonance frequency 2.4 GHz and 5.2 GHz thereby covering the required frequency-bandwidth of 2.4- 2.4836 GHz and 5.15-5.35 GHz, which are widely used in Wireless LAN (WLAN). The characteristics of antennas are proposed and analyzed for instance input impedance, S₁₁ parameter and far field radiation patterns. The antenna is analyzed by finite difference time domain (FDTD) method which can predict and analysis of the electromagnetic responses of complex problems.
