Compact CPW-Fed UWB Antenna with Quadruple Band-Notched Characteristics

A compact CPW-Fed UWB antenna with quadruple band-notched characteristics is proposed. The antenna consists of a flower-shaped radiator, a ground plane and a coplanar waveguide (CPW) feed-line. The UWB antenna can efficiently operate in the frequency band of 2.7-10.6 GHz. To obtain four rejected bands, four Meander-line slots are etched on the radiator and ground plane. Rejected frequency bands of C-band (3.60-4.32 GHz), WLAN (5.17-5.32 GHz), WLAN (5.80-5.93 GHz), and X-band (7.13-7.88 GHz) are obtained by the four slots. Both design and analysis of the proposed antenna are detailed in the paper.
