这封信提出了一种新颖的双频可调谐陷波天线。该天线由一个微带超宽带（UWB）天线和两种新颖的开槽结构组成。通过调节陷波结构上的电容，得到了可调谐的陷波。单极天线在3.1 - 10.6 GHz工作良好。低频陷波可在3-4 GHz上调整，高频陷波可在5-6 GHz上调整，避免了WiMax和WLAN窄带通信系统对UWB通信系统的影响，提高了天线系统的性能。同时，通过对开槽天线表面电流分布的分析，研究了开槽波的产生原理。最后，制作了一个带陷天线样机，并进行了测试，仿真结果与测试结果基本一致。
This letter presents a novel dual‐band tunable band‐notched antenna. The antenna consists of a monopole ultrawideband (UWB) antenna and two kinds of novel notched structures. A tunable notched wave is obtained by adjusting the capacitance on the notched structure. Monopole antenna works well on 3.1‐10.6 GHz. The low frequency notched wave can be adjusted on the 3–4 GHz, and the high frequency band notched wave can be adjusted on the 5–6 GHz, which can avoid the influence of the WiMax and WLAN narrowband communication system on the UWB communication system, and improve the performance of the antenna system. At the same time, through the analysis of the surface current distribution of the notched antenna, the principle of the notched wave is studied. At last, a prototype of the band‐notched antenna is fabricated and measured whose simulation is consistent with the measurement.
