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.

Wideband E-Shaped Microstrip Antenna for Wireless Sensor Networks

“…However, bandwidth enhancement and size reduction are becoming major design considerations for practical applications of microstrip antennas due to the improvement of one of the characteristics, which normally results in degradation of the other (Xiao et al, 2006). In the past few years, new designs arising from the Planar Inverted-F Antenna (PIFA), one of the studies (Ibnyaich et al, 2011) focused on the development of wideband planar inverted-F antennas. They used two different studies to obtain the wideband operation.…”
