Coplanar waveguide (CPW) antennas, notched band, ultra wideband (UWB)Abstract
In this manuscript, a new CPW-fed slot antenna with two band-notches for ultra-wideband communication systems is proposed. The antenna contains a trapezoid-shaped patch and a slotted ground plane. To achieve two notched bands, both of the inverted L-shaped strip and triangle-shaped element connecting to patch by via are used. The designed antenna is printed on an FR4 substrate with compact size of 20×27 mm2 . Moreover, the antenna has been successfully fabricated and measured, indicating extended impedance bandwidth (3-11.2 GHz, VSWR?2) and dual bandnotched (3.2-3.9 GHz and 5-5.9 GHz) respectively
