Abstract: This paper presents a study on a modified planar inverted-F antenna (PIFA) with a small ground plane (7mm x 12mm) mounted on a printed circuit board (PCB) of a mobile phone handset (40mm x 100mm) operating at 5.2 GHz. Whilst it inheriting the attractive features of PIFAs, such as compact size and low profile, the modified antenna exhibits low coupling to the PCB.
Introduction
The planar inverted-F antenna (PIFA) is popular for the small mobile terminals for its attractive features of compact size and good performance [1]. Since portable wireless devices, such as handsets and personal digital assistants
