摘要: 考虑到超宽带通信系统对现有其它无线通信系统运行的影响，设计一种具有WiMAX陷波特性的超宽带天线。该天线尺寸大小为0.8 mm × 30 mm × 34 mm，采用圆弧状T形贴片作为辐射单元，并通过在该辐射贴片上开L形槽来实现陷波特性。仿真实验结果表明：天线的带宽为2.9~10.8 GHz，同时具有3.2~3.8 GHz的陷波，平均增益约为4.0 dBi，并具有稳定的准全向性辐射特性。该天线能够满足多种超宽带通信系统的应用要求。
Abstract: Considering the effects of ultra wideband communication systems on the operation of the other existing wireless communication systems, a kind of UWB antenna with WiMAX notched-band is proposed. The size of the antenna is 0.8 mm × 30 mm × 34 mm. A circular arc shaped T patch is used as the radiating element of the antenna, and a notched band is realized by embedding the L shaped slot on the radiating patch. The simulation results show that the bandwidth of the antenna is 2.9 - 10.8 GHz with the notched band of 3.3 - 3.7 GHz; the average gain of the antenna is about 4.0 dBi; and it has a stable quasi omnidirectional radiation characteristic. The antenna can meet the application requirements of a variety of ultra wideband communication systems.
