摘要: The numerical design method for a microstrip-fed circular-disc monopole (CDM) antenna operating within the ultrawideband (UWB) from 3.1 to 10.6 GHz is initially studied. By simply embedding a pair of U-shaped slots into the ground plane, a band-rejection (band-notch) function at around 5 GHz is achieved. For impedance matching and fine tuning of this proposed antenna, a small rectangular slit is inserted at the top centre of the ground plane. Except within the rejection band, the gain and time-domain characteristics of this antenna has successfully demonstrated that it is applicable to any high data rate short-range wireless communication system that requires a stable signal transmission in the UWB application. The performances of a common UWB CDM antenna without band-rejection function and a similar one with a slot loaded in the radiating circular patch are also investigated and compared with the proposed antenna
