摘要

本文提出了一种新型双频可调的陷波天线,该天线是由一个单极子超宽带天线和两种新型陷波结构组成。通过在陷波结构上加载可变电容,得到了陷波可调。单极子天线在3.1-10.6GHz上良好的工作,低频段的陷波在3-4GHz上可调,而高频段的陷波在5-6GHz上可调,避免了Wi Max和WLAN窄带通信系统对超宽带通信系统的影响,,提高了天线系统性能。同时,通过对陷波天线表面电流分布进行分析,研究了陷波产生的原理。
This paper presents a novel dual frequency tunable band-notched antenna. The antenna consists of a monopole ultra wideband antenna and two kinds of novel notch structures. A tunable notch is obtained by loading the variable capacitance on the notch structure. Monopole antenna works well on 3.1-10.6GHz The low frequency notch can be adjusted on the 3-4GHz, and the high frequency band notch can be adjusted on the 5-6GHz, which can avoid the influence of the Wi Max 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 notch antenna, the principle of the notch wave is studied.
