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WiMAX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S11在整个频段<-10 dB。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。

Abstract:

A novel ultra-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 dualband-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 S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.

Key words: ultra wideband antenna;double notch characteristics;antenna design
