Abstract

A small-sized compact CPW feed ultra-wideband (UWB) antenna with dual-band notched characteristic is proposed. The antenna consists of the radiation pattern, ground plane and the CPW feed on one side of the substrate, which is used to support the antenna and on the other side are two resonators with filter characteristic. By integrating the filters with the antenna, the antenna can suppress the WLAN band (5.15 ~ 5.35 GHz and 5.725 ~ 5.825 GHz) successfully which makes the use of the frequency resource and decreases the electromagnetic interference (EMI). The size of the band-rejected antenna is small, just 24 mm × 30 mm × 0.5 mm.
