Abstract

In this article, a novel compact planar ultra–wideband (UWB) monopole antenna with dual band-notched characteristics is proposed. Two notched frequency bands are achieved by using a novel inverted V-shaped stub and a pair of novel L-shaped parasitic strips around the radiation patch. Two notched frequency bands are obtained in the WiMAX (3.3-3.6 GHz) and WLAN (5.15-5.85 GHz). Simulated and measured results show that proposed antenna could operate from 2.14 to11 GHz (135%), defined by voltage standing wave ratio VSWR< 2. The proposed antenna has a small size of 24×28×1.6 mm3 and the prototype of the antenna is simulated and fabricated and tested. In addition, proposed antenna is evaluated and compared with antennas presented in recent papers, using analytical hhierarchy pprocess, which is a multi-criteria decision-making method.
