A CPW-FED C-Shape Arc Slotted Monopole UWB Antenna with Band-Notched Characteristic

In this paper, a printed C-shape monopole antenna with band-notched feature for UWB application is presented and investigated. By inserting a circular arc slot on the C-shape radiator, the band-notched characteristic is achieved. The measured results show that the proposed antenna meets the requirement of wide-working band-width of 3.1–10.6 GHz with VSWR < 2, while avoiding the interference with the WLAN band (5.15–5.825 GHz). The proposed antenna has a compact size, good radiation characteristics, ultra wide band-width, and good time-domain behaviors to satisfy the requirement of the current wireless communications systems.
