Elliptically shaped ultra‐wideband patch antenna with band‐notch features

Abstract

Abstract A series of ultra‐wideband antenna using an elliptically curved patch is investigated. The band‐notch feature is realized by cutting off a bended slot, which can be tuned. S 11 is controllable by the length of the tunable slot. The antenna exhibits good omnidirectional performance across the operation bandwidth. © 2008 Wiley Periodicals, Inc.
