基于开口谐振环的风车型多频天线
|
摘要
提出了一种基于开口谐振环的新型风车型多频天线。为了使天线工作在UMTS(2100)、WLAN(2.45 GHz)、Wimax(3.5 GHz)及X-band卫星下行通信(7.2 GHz～7.6 GHz)频段上,设计了风车型四频天线。基于该天线,通过在馈线侧加超材料开口谐振环,改变天线表面电流分布及辐射特性,衍生新工作频段,实现了天线的五频与六频。通过改变开口谐振环的参数实现了天线新频点可调,而且新频段能够单独控制。最终天线的新频段包含WLAN(5.2 GHz)与WLAN(5.8 GHz)两个频段,实验与仿真结果一致,具有较好的实用价值。
The novel windmill multifrequency patch antenna is proposed. In order to make the antenna work at UMTS(2100),WLAN(2.45 GHz),Wimax(3.5 GHz)and X-band downlink satellite system(7.2 GHz～7.6 GHz),a windmill quad-frequency patch antenna is designed firstly. Then based on this antenna,by adding split ring resonator near the feed line,the new penta-frequency and six-frequency antennas are derived owing to the variations of current distribution and radiation characteristic. The new frequency points of antenna can be effectively adjusted by changing the split ring resonant parameters,and the new bands of antenna can be controlled individually. Finally the new bands of WLAN(5.2 GHz)and WLAN(5.8 GHz)are achieved. The results of test are consistent with those of simulation,and this new antenna has good practical value.
