中部加载在线天线的应用研究

Application Research on the Middle Loaded Online Antenna

借助仿真软件,在普通偶极子天线中部加载一个方环,并对比引入不对称缺口和缺口内引入直线的措施,证实并分析了通过这三种改变天线结构的加载技术,可以有效降低天线高频谐振频率、增加谐振点。同时可以根据方环的位置、大小可以相应地调整谐振频率与谐振深度。以上的这些研究结论可能为偶极子天线在广播收发领域的发展起到一定的作用。

With the aid of simulation software,a square ring is loaded in the middle of the common dipole antenna,and the measures of introducing an asymmetric notch and a straight line in the notch are compared.It is proved and analyzed that the three loading techniques of changing the antenna structure can effectively reduce the high frequency resonance frequency and increase the resonance point of the antenna.At the same time,the resonance frequency and resonance depth can be adjusted accordingly according to the position and size of the square ring.These conclusions may play a role in the development of dipole antenna in the field of radio transceiver.
