This paper addresses an approach to synchronise with the UWB spectrum, as well as elaborating on the phenomena of frequency interference within UWB antennas. The proposed design occupies a compact volume of 30x30x0.8mm³. The antenna consists of a hexagonal shaped structure printed over FR4 substrate. For bandwidth improvement, a defected ground structure (DGS) was first introduced and secondly a stub was added over the feeding strip to accomplish a larger bandwidth. To achieve the frequency band notched characteristics, a half hexagon slot was etched onto the radiator, that creates a notch at 5.2 GHz, then by introducing a full hexagon slot, another rejected band was created at 10 GHz. The proposed antennas show a stable performance in the UWB spectrum as well as achieving superior dual band-notch features at desired frequency bands.
