Design of tri band Planar Inverted F Antenna

In this paper, we are presenting a tri-band Planar Inverted F Antenna (PIFA) for mobile application. PIFA basically consist of ground plate, patch, feed and shortening pin connected to ground plate. Antenna is designed to tune at 916MHz, 1800MHz and 6.2GHz frequencies. Designed antenna has been simulated in CST 2012 software and various parameters of antenna are studied and presented. The designed antenna also has been fabricated manually and tested on vector network analyser (VNA) and has met the performance criteria for mobile application.
