Abstract :
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.
