摘要 为了避免超宽带通信中其他系统的干扰问题,设计了一种双阻带的超宽带天线。通过采用一种不等宽的条带结构,从而较好地实现了双阻带特性。除了在要求屏蔽的Wi MAX频段（3.3~3.7 GHz）以及X频段的卫星通信下行频段（7.25~8.395 GHz）,回波损耗S11在整个频段〈-10 d B。通过仿真设计结果表明,该天线在3.38~3.58 GHz和7.29~8.13 GHz处均具有较好的阻带性质。 A novel uhra-wideband （UWB） antenna is proposed in this paper to avoid the interference from other systems. This paper presents a strip with unequal width to apply on the UWB antenna in order to achieve dual- band-notched characteristics. Except for the two subbands for WiMAX （ 3.3 - 3.7 GHz） and the downstream X- band （7. 25 -8. 395 GHz）, the antenna＇s return loss $11 is better than - 10 dB at all frequencies. Simulation of the designed antenna shows a good band notched characteristic at frequencies 3.38 -3.58 GHz and 7.29 -8.13 GHz.
