Planar inverted F antennas (PIFA) and micro-strip antennas are widely used in wireless devices as they can easily be integrated or hidden within wireless terminals. Conventional PIFA and micro-strip antenna designs typically offer narrow bandwidth of about 3-8 %. It has been proposed that the bandwidth of the PIFA can be increased by reducing the ground plane size and through the use of various feeding methods or stacked patches. Recently, some of these methods include using passive elements. Numerous studies have also been carried out to enhance the bandwidth of the conventional micro-strip antenna. Most of the proposed methods involve modification to the feeding structure or the inclusion of shorting post. While all the above mentioned methods offer various level of enhancement in operating bandwidth, this poster presents a wideband antenna using a combination of the various known methods to realise an antenna for use within the UHF band.
