Abstract

A novel microstrip-fed printed monopole antenna is proposed for WLAN and WiMAX applications. Using a modified fork-shaped strip, multiple impedance bandwidths covering 2.4/5.2/5.8 GHz WLAN and 5.5 GHz WiMAX bands are obtained. In addition, a dual L-shaped parasitic plane is inserted on the bottom of the FR4 substrate to cover the 3.5 GHz WiMAX band. Omnidirectional radiation patterns with appreciable gains over the operating bands are obtained by the fabricated antenna with a compact size of 34.5 × 18 mm². Thus, the antenna is suitable for multi-band wireless communication applications.
