摘要

介绍了一种带陷波超宽带单极天线。首先，采用径向贴片设计了超宽带单极天线。该路径采用微带线馈电。在UWB系统的频率范围内，即3.1GHz到10.6GHz，天线的回波损耗小于-10dB。为了抑制UWB和WLAN之间的干扰，需要在UWB通带中插入一个陷波带。两个对称的微带谐振器外部加载到微带馈线上，形成一个陷波带。通过调整加载谐振腔的大小和位置，可以控制陷波带的频率范围。实现了5.2GHz到5.8GHz的陷波带。实验结果表明，该天线在整个工作频率范围内具有稳定的辐射方向和增益特性。

Novel band-notch monopole ultra-wideband antenna with external load

A band-notch ultra wideband monopole antenna is presented in this paper. Firstly, an ultra-wideband monopole antenna is designed using a radial patch. The path is fed by using microstrip line. The return loss of the antenna is less than -10dB within the frequency range of UWB system, i.e. from 3.1GHz to 10.6GHz. To restrain the interference between UWB and WLAN a notch band shall be inserted in the UWB passband. Two symmetrical microstrip resonators are externally loaded to the microstrip feed line to form a notch band. The frequency range of notch band can be controlled by adjusting the size and the position of the loaded resonator. A notch band from 5.2GHz to 5.8GHz is achieved. As the experimental results show the proposed antenna has steady characteristics of radiation direction and gain on the whole working frequency range.
