Ground plane effects on planar inverted-F antenna performanceGround plane effects on planar inverted-F antenna (PIFA) performance
M.-C. Huynh and W. Stutzman Abstract: The planar inverted-F antenna (PIFA) is popular for portable wireless devices because of its compact size and low prole. The PIFA is designed to operate with a ground plane and the ground plane is an integral part of the antenna assembly. In fact, the ground plane size is the limiting factor for the PIFA in many applications. Some work has been reported on the performance of PIFAs mounted on a conducting box of xed size; however, what is lacking is a parametric study on the antenna behaviour as a function of geometry or antenna position and orientation on a nite ground plane. This paper presents results from a comprehensive investigation on the performance of a conventional PIFA mount
