A Novel Quad Band Compact Meandered PIFA Antenna for GPS, UMTS, WiMAX, HiperLAN/2 Applications

摘要

In this paper a quad band compact meandered PIFA antenna for various wireless applications is proposed. The proposed antenna is designed as meandered PIFA Antenna in order to obtain high gain, wide bandwidth, multiband and good efficiency. The method of using meandered slits on top radiating patch is use to increases the gain and further reduces the size of conventional PIFA antenna. It also enhanced the bandwidth and current path of the antenna. The proposed antenna is only 20mm × 10mm in area and built on a very small ground plane of size 60mm × 40mm using FR4 substrate of thickness 1.57mm. The proposed antenna covers GPS, UMTS, WiMAX, Hiper LAN/2 and ISM bands. The simulation results are analyzed with the help of HFSS software. Following parameters of the antenna, including structure of the proposed antenna, return loss, quad-band frequencies, bandwidth, and simulated distribution of current density, radiation patterns are presented and discussed. It is also noted that proposed antenna obtained very high gain of 26.4689dB.
