摘要：
A miniaturised coplanar waveguide-fed multiple notched monopole antenna for ultra-wide bandwidth (UWB) application is presented. By introducing multiple inverted L-shaped stubs embedded within a polygonal shaped monopole antenna, multiple notches can be achieved. A prototype antenna with triple band-notched at WiMAX, WLAN, and X-band is designed and fabricated. The proposed antenna has an impedance bandwidth of 3-12 GHz with a voltage standing wave ratio of <2 except for the selected notched bands. The main advantage of the antenna is its miniaturised size (21 x 14 mm(2)), as well as the straightforward design. The antenna has a unipolar configuration and good omnidirectional radiation pattern with negligible distortion which is suitable for UWB applications.
