Development of Wideband Planar Inverted-F Antennas for Wireless Application
Abstract
Problem statement: Due to the rapid development in wireless communication, the antennas capable of broad-band operations are very demanding in cellular communications systems. Among various possible antennas, planar inverted-F antennas (PIFAs) have the advantages of low profile and compact size and are very suitable for present-day wireless communication application. Approach: This study demonstrates a very effective method of bandwidth enhancement for planar inverted-F antenna. It was done by optimizing the width of feed plate and shorting plate, then by adding a parasitic element. Results: The obtained results of our developed wideband antenna was an impedance bandwidth of 72.8% for S11<-10 dB from 1.74-3.54 GHz which could cover GPS, DCS, IMT-2000, 2.4GHz WLAN, 3.5 GHz WIMAX applications. Conclusion: As the antenna was successfully researched and well optimized, and desired results were achieved.
