Response of Planar Inverted F Antenna over Different Dielectric Substrates
In modern era, a demand has increased to design antennas having multiband and wideband characteristics for mobile terminals. This paper expresses the bandwidth, return loss and gain variations of a Planar Inverted F Antenna. Here, the antenna is built on a small ground plane size of 60x60mm. In this paper, planar inverted F antenna with a radiating patch of fixed dimensions of 15.3x15.3mm is studied using different dielectric substrates. The causes of the dielectric constant of perfect substrates and lossy substrates on the return loss, impedance bandwidth, resonant frequency and the gain are explored.
