In this paper we have used the relatively simple planar inverted-F antenna (PIFA) at 2.4 GHz to illustrate the impact of an antenna’s environment on its performance. The important impacts of circuit board area, component placement and proximity of conducting surfaces are often ignored until late in a product design cycle when changes are costly and schedule impact is most painful.
