Abstract :
A study on a modified planar inverted-F antenna (PIFA), operating at 5.2 GHz within the IEEE802.11a WLAN frequency band (5.15-5.35 GHz) with a very small ground plane (7 mm×12 mm) and its application to multiple input multiple output (MIMO) systems is presented. While it inherits the attractive features of PIFAs, such as compact size and low profile, the modified antenna exhibits low coupling to the printed circuit board (PCB). A 2-element PIFA array is implemented on a mobile handset PCB and an isolation better than 28 dB is achieved in both simulation and measurement.
