A small size wideband planar inverted-F antenna for USB dongle devices

In this paper a small size wideband planar inverted-F antenna (PIFA) is proposed which operates at 4G LTE (2.3-2.4 GHz) and (2.5-2.7 GHz), Bluetooth/WLAN (2.4-2485 GHz) and WiMAX (3.4-3.6 GHz) range. The proposed antenna has many advantages like small size and wide operation bandwidth. The antenna portion has dimensions as 20mm * 18mm and the overall dimensions are 44mm * 25mm * 0.8mm which can be easily implemented in USB dongle. Simulated and measured results are in good match and the results are also compared with already implemented design available in literature.
