摘要：
In this article, a novel compact UWB antenna with 3.5/5.5 GHz band-notched characteristics is proposed. The proposed antenna consists of an opening elliptic annulus and two resonating structures. One is inserted into the terminal of the radiating patch, and the other is connected to the beginning of a radiating patch via two metallic holes. The measured impedance bandwidth defined by VSWR < 2 from 3 to 11 GHz, with the dual notched bands of 3.4-4 GHz and 5-5.9 GHz, is obtained. The proposed antenna is successfully simulated, designed, and measured with broadband matched impedance, good radiation patterns and constant group delay. Additionally, the conceptual equivalent circuit models, combined with input impedance, are also shown for further analysis of the band-notched characteristics.
