发布时间：2019-03-24 17:00
【摘要】：采用SRR环和CLP环两种不同谐振单元,构造了一种新型超介质结构单元。该单元的电谐振和磁谐振的谐振频点比较接近,易于频带融合,从而拓展超介质材料双负(介电常数和磁导率都为负)特性的频率带宽。利用加载的方法,在单极子天线上加载该种新型超介质结构单元,以改善天线的辐射特性。利用电磁仿真软件对其进行了仿真设计和优化。仿真结果表明,该天线实现了超宽带工作,在3.8~14GHz的频率范围内,驻波比小于2;同时,天线实现了高增益特性,在整个频率范围内,增益都高于7dB。最后,对天线进行了加工测试,实验测试结果与仿真结果基本吻合,进一步验证了该天线的工作性能。
[Abstract]:A new type of superdielectric structural element is constructed by using two different resonant elements: SRR ring and CLP ring. The resonant frequency point of the cell is close to that of magnetic resonance, so it is easy to fuse the frequency band, thus expanding the frequency bandwidth of the double negative (both dielectric constant and permeability) characteristics of the superdielectric material. In order to improve the radiation characteristics of the monopole antenna, this new type of superdielectric structure element is loaded on the monopole antenna by means of the loading method. The electromagnetic simulation software is used to design and optimize the simulation. The simulation results show that the antenna operates ultra-wideband, and the VSWR is less than 2 in the frequency range of 3.8~14GHz. At the same time, the antenna achieves high gain characteristics, and the gain is higher than 7dB in the whole frequency range. Finally, the processing test of the antenna is carried out. The experimental results are in agreement with the simulation results, and the performance of the antenna is further verified.
