A Novel Miniature Band-Notched Wing-Shaped Monopole Ultrawideband Antenna

A small band-notched monopole ultrawideband (UWB) antenna is proposed in this letter. In this antenna, the band-reject is achieved by attaching a strip to the hollow center of a wing-shaped monopole. The height and width of the strip are dependent on the center frequency of the notch band. The proposed antenna is printed on a very small (11 × 15 mm
²
) substrate. The measured results reveal that the proposed antenna offers a wide bandwidth covering 5-15 GHz with a notched band covering a 6.7-7.1-GHz IEEE INSAT/super-extended C-band frequency. The proposed antenna shows very narrow and accurate band rejection.
