摘要：

考虑到超宽带（UWB）无线通信系统对现有无线通信系统工作的影响，设计一种具有IEEE WiMAX和IEEE WLAN双陷波特性的超宽带天线.该天线尺寸大小为1.0 mm×20 mm×25 mm，采用扇形阶梯状贴片作为主辐射单元，通过在该辐射贴片上嵌入L形和半圆环形槽缝来实现陷波特性，并且在主辐射单元2边增加附加矩形贴片来展宽天线阻抗带宽.仿真实验结果表明：天线的阻抗带宽为3.0~12.9 GHz，同时具有3.3~3.8 GHz和5.2~5.8 GHz双陷波，平均增益约为4.5 dB，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:

Aimed at the effects of ultra wideband (UWB) wireless communication systems on the operation of the other existing wireless communication systems，a kind of UWB antenna with IEEE WiMAX and IEEE WLAN notched-bands is proposed.The size of the proposed antenna is 1.0 mm×20 mm×25 mm.A sector step-shaped patch is used as the master radiating element of the antenna，and twp notched bands are realized through embedding the L-shaped slot and half ring-shaped slot on the radiating patch.Furthermore，the impedance bandwidth of the antenna is broadened through adding two rectangular patches beside the master radiator.The simulation results show that the bandwidth of the antenna is 3.0~12.9 GHz with the notched bands of 3.3~3.8GHz and 5.2~5.8GHz，the average gain of the antenna is about 4.5 dBi，and it has a stable quasi- omnidirectional radiation characteristics.The antenna can meet the application requirements of a variety of ultra wideband communication systems.

Key words: ultra-band antenna, double band-notched characteristics, slot antenna
