Feeding Position Effects on the Performance of Planar Inverted Folded Antenna

PIFA's are used in many applications like PCS, mobile handsets, Bluetooth, WLAN, WI-FI etc. The position of the feed and the patch dimension will play a major role in the performance of the antenna along with substrate, material. The method of improving the bandwidth and reduction of size of the antenna can be alone carried by selecting these PIFA antennas. The design and characterization of the PIFA with respect to the feeding position is to be analyzed in this paper. Different feeding positions are considered and verified the output parameters of the antenna and analyzed the results.
