This study presents a new design of a triple band-notched ultra-wideband antenna. The designed structure of the antenna is based on two radiating strips, and a microstrip feed-line on the front, an inverted T-shaped element and a partial ground on the back. By etching a slot off the ground plane, another resonance is excited resulting in the extended bandwidth. The antenna with new structure occupies a small size of 20 × 14 mm2. The measured results show that the antenna has a wide bandwidth from 2.8 to 12.5 GHz for voltage standing wave ratio less than 2 apart from the rejected bands from 3.0 to 3.8 GHz, 5.1 to 6.1 GHz and 7.8 to 8.9 GHz. Meanwhile, radiation patterns and gain at various frequencies have been given.
