Abstract

By coupling a fractal loop resonator onto the back of a loaded-fractal loop monopole and a shorted loop, a new triple-band USB dongle antenna has been achieved and presented. The proposed antenna supports WLAN (2.4-2.5 GHz and 5.15-5.875 GHz) and WiMAX (3.4-3.6 GHz) applications. Omnidirectional radiation patterns for the three bands are observed. The overall dimensions of the fabricated prototype are 10 mm × 42 mm ×0.8 mm, which is suitable for USB dongle. The design of proposed antenna and experimental results are discussed.
