中文摘要:
      针对模式压缩偶极子天线目前存在的高副瓣问题,提出一种低副瓣三次模压缩偶极子天线的设计,通过采用在偶极子天线上加载弯折电感的方式,获得较大压缩系数值,减小反向电流的辐射口面,从而设计出低副瓣高增益的模式压缩天线,实现了-15.35 dB的低副瓣和5.11 dBi的增益性能,降低了互扰,增大天线的传输距离和传输速率. 为验证仿真模型的有效性,利用PCB技术加工出实物并进行测试,其仿真和测试结果比较吻合.
英文摘要:
      In this paper,The design of a low side-lobe compressed dipole resonating at the third mode is proposed in order to solve the problem of a high side-lobe in the mode compressed dipole antenna. This paper adopts a method of loading a bent inductor on the dipole antenna to achieve a larger compression coefficient,thus the radiation interface of the reverse current is reduced. Finally,the target of designing mode compression antenna with low side-lobe and high gain is realized,which achieves a low side-lobe of -15.35 dB and a gain of 5.11 dBi. The mutual interference is reduced,and the transmission distance and speed are increased. In order to verify the validity of the simulation model,the PCB technology is used to manufacture the model and test it. The simulation results are in good agreement with the test results.
