Abstract:
In wireless communication systems，in order to overcome the mutual interference among systems，an UWB monopole antenna with dual band-notched characteristic is proposed using band-suppressed technology. Using the techniques of loading and slotting makes the returned loss of the antenna less than -10 dB in the band of 2.6~14.6 GHz. Through slotting on the ground plane and the radiating patch，VSWR is greater than 2 in the range of IEEE802.16 of 3.3~3.6 GHz，C-wave satellite communications system 3.7~4.2 GHz，and IEEE802.11a of 5.15~5.825 GHz frequency band. Results of simulation and test show that the antenna has good function of suppression，simple structure and small size.
