摘要
A simple and novel ultra-wideband microstrip-fed antenna with dual band-notched characteristic is presented. By etching a pair of asymmetrical spurlines on the feedline, two notched bands of 600 MHz (3.95-4.55 GHz) and 650 MHz (5.35-6.0 GHz) are achieved. Measured results show that this antenna operates from 2.5 to 12.0 GHz for voltage standing wave ratio less than 2, except two frequency notched bands of 3.95-4.55 GHz and 5.35-6.0 GHz. Moreover, this antenna has good omnidirectional radiation patterns in the H-plane.
