摘要：

A novel printed ultrawideband (UWB) slot antenna with reconfigurable band-notch characteristics is presented in this letter. The proposed antenna consists of a modified rectangular radiation patch with a circular and three rectangular-shaped slots etched on it. Additionally, by cutting two triangular-shaped slits on a modified ground plane, practical fractional bandwidth of more than 120% (3.12-12.51 GHz), defined by - 10 dB return loss, is achieved. In order to generate single and dual band-notch characteristics, two p-i-n diodes are mounted across the circular slot. The designed antenna has small size of 20 x 20 mm(2) with switchable single notched bands of 3.12-3.84 GHz WiMAX and 5-6.07 GHz WLAN, when diode 1 and diode 2 are respectively on. Also, dual bands of 3.12-3.82 and 4.9-6.06 GHz are eliminated from whole frequency band when both diodes are concurrently on.
