Performance analysis of a printed super-wideband antenna

Performance in both frequency-domain and time-domain for a printed super-wideband antenna is studied and presented in this article. The proposed antenna consists of a corner-rounded ground plane, a tapered microstrip feeder and a novel radiating patch which is made by one half-disc and one half-ellipse. This configuration allows to implement a ratio impedance bandwidth more than 25:1 for voltage standing wave ratio (VSWR) < 2. Critical antenna characteristics including antenna transfer function, group delay and time-domain pulse responses are experimentally investigated and analyzed in detail by setting up a transceiving antenna system, which give designers a thorough understanding and useful informa- tion about antenna performance and application it exhibits behind the extremely broad bandwidth.
