Abstract
This paper presents Design and Implementation of microstrip patch antennas for WLAN applications. Here Microstrip patch antenna for WLAN frequency (2.4GHz) was designed and simulated using different feeding techniques. There are various feeding techniques Microstrip line feed, Inset fed, Co-axial feed, Aperture coupled feed, and Proximity coupled feed used in Microstrip patch antennas. We have chosen Microstrip line feed and Co-axial feed due to the advantage that it can be easily fabricated. The simulation of microstrip antenna is carried out using ADS2009. The return loss, beamwidth and gain for microstrip line feed -12.5dB, 110o and 6dB respectively. The return loss, beamwidth and gain for co-axial fed patch antenna are -29dB, 150o and 4dB respectively. The Microstrip antenna substrate is FR4 of dielectric constant 4.6 and thickness 1.6mm. we are used same substrate for all the feeding techniques. The co-axial feed antenna resonated at 2.4GHz and Microstrip line fed antenna resonated at 2.404GHz.
