Abstract :
A simple design of multilayered quad band-notched ultra-wideband (UWB) antenna is presented. The antenna is compact in size, suitable for UWB applications, and exhibits quad narrow band frequency notches to suppress the interference of the nearby wireless communication systems within a UWB frequency range. The narrow band notches are realised by adding closed-loop ring resonators designed to cover the 3.3-3.7-GHz, 4.5-4.8-GHz, 5.15-5.35-GHz, and 5.725-5.825-GHz bands. The antenna has been fabricated and tested for demonstrating the desired characteristics.
