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 600 MHz (3.95 4.55 GHz) 650 (5.35 6.0 are achieved. Measured results show that this operates from 2.5 to 12.0 GHz for voltage standing wave ratio less than 2, except frequency 3.95 5.35 GHz. Moreover, has good omnidirectional radiation patterns in H-plane.
