Abstract

Abstract: The design of miniaturized micro strip antenna plays a very vital role in development of portable wireless 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 which can be accommodated in the typical space available in a communication device. The planar inverted –F antenna is very popular for such portable wireless devices because of its small size and low profile. In this paper, a planar inverted –F antenna (PIFA) with a small triangular shape ground plane and square shape radiating element has been introduced to work on 1.32 GHz. This antenna is 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.
