Abstract

A printed discone antenna with dual-band notched characteristics is presented for ultra-wideband applications. The proposed antenna consists of a radiation patch which has an outline expressed by binomial function and a trapeziform ground plane. Dual band-stop performance is achieved by etching a pair of Z-shaped slots on the ground plane and protruding a pair of π-shaped strips in the elliptical slot cut in the radiation patch, respectively, which can reject potential interference with the 3.25-3.8 GHz and 5-6 GHz bands. Surface current distributions and input impedance of the antenna are given to analyze the effects of the two resonant structures. The characteristics of the notched bands can be controlled independently by tuning related parameters. Moreover, the performances of the antenna are validated along with simulated and measured results.
