Band-notched Wideband Antenna
The present invention provides a wideband antenna (10) comprising: a substrate (13); a radiating element (12) supported on the substrate and coupled to a transmission feed-line (14); and a resonator (20) mounted in proximity to the radiating element and occupying an area that is covered at least in part by the radiating element. In embodiments of the invention, the resonator (20) is configured to resonate at a predetermined frequency within an ultra-wideband spectrum so as to suppress transmission of signals by the antenna in a notch band centred on the predetermined frequency.
