Design of a novel elliptical monopole UWB antenna with dual band-notched function

In this article. a novel compact elliptical monopole ultra-wideband antenna with dual notched bands is proposed and investigated. The dual-notched characteristic is realized by cm elliptic arc-shaped slot inserted in the elliptical monopole and a compact coplanar waveguide resonant cell in the feed line. The measured results show that the frequency band of VSWR <= 2 covers 3.1 to 10.6 GHz UWB band, while the notched frequency hands are 3.45-3.75 GHz which covers 3.5 GHz WIMAX and 5-6 GHz which covers 5.15-5.85 GHz WLAN band, and the two notched bands are separately achieved. The proposed antenna has a monopole-like radiation patterns. Gain of the proposed antenna and transfer junction study show that dual band-notched characteristics achieved which conforms with the results of VSWR. (C) 2010 Wiley Periodicals, Inc.
