pp: 964-967A Compact Printed Antenna with Band-stop Characteristic for UWB ApplicationSeokjin Hong, Hee Jun Lee, Soonyong Lee, and Jae-Hoon Choi doi:10.2529/PIERS060825233410 Downloads: 1208 Abstract:A Compact antenna with a band-stop characteristic for ultra-wideband application is proposed. To increase the impedance bandwidth of the proposed antenna, a tapered ground and circular slot are used. By attaching an inverted Y-shaped open-circuited stub in the circular ring, the band-stop characteristic is obtained. The designed antenna satisfies the voltage standing wave ratio requirement of less than 2.0 in the frequency between 3.12 GHz and 10.73 GHz while showing the band stop performance in the frequency band of 5.15 GHz to 5.78 GHz. This antenna shows an omnidirectional radiation pattern similar to that of a monopole antenna.References:1. Agrawall, N. P., G. Jumar, and K. P. Ray, "Wideband planar monopole antennas," IEEE Trans.
