Design and analysis of a compact CPW-Fed UWB antenna with quadruple notched bands

A compact ultra-wideband (UWB) antenna with quadruple notched bands is proposed. The antenna consists of a fork-shaped radiator, a ground plane and a coplanar waveguide (CPW) feed-line. The UWB antenna can efficiently operate in the frequency band of 3.1-11 GHz. To obtain four rejected bands, four slots are etched on the radiator and ground plane. Rejected frequency bands of WLAN (5.72-5.80 GHz), WLAN (5.28-5.40 GHz), C-band (3.65-4.21 GHz) and ITU (7.92-8.5 GHz), are realized by a U-shaped slot, a Cap-shaped slot and a Meander-line slot. Both design and analysis of the proposed antenna are detailed in the paper.
