Abstract

The design of miniaturized antenna plays a very important role in development of portable communication systems. The resonance frequency, bandwidth and gain of an antenna directly depend on its dimensions. The idea is to find best geometry and structure. The planar inverted �F antenna is very popular for such portable wireless devices because of its compact size and low profile. In this paper, four designs of planar inverted �F antenna (PIFA) with a small square shape radiating element has been introduced to work between 1.67 GHz to 1.8 GHz for UAV, DCS and GSM applications. These antennas are low cost simple in design and easy to fabricate. The bandwidth provided by the PIFA is wide as compared to a conventional micro strip patch antenna of half wavelength. The dimensions of antenna have been optimized to have a wide bandwidth (9.47 %) with air as dielectric used in this design. The effect of different ground plane sizes has been analyzed. The results will be very useful in the design of PIFA for applications requiring a small ground plane. Simulated and measured results are presented for smallest structure.
