| 摘 要： | 为满足通信系统在天线增益方面的需求,通过将透波增强特性应用于天线设计中,提出了一种新型高增益天线。运用高频仿真软件Ansoft HFSS对天线进行了优化仿真,并加工出实物进行测试。测试结果显示,天线增益为12.9 dB,相对于传统的平板天线提高了6 dB。此外,由于设计的结构引入了环形孔结构和褶皱结构,天线的波瓣宽度测量结果为30°,相较于传统天线也减小了102°,天线的性能得到大幅提高。

| Abstract: | A novel planar high gain antenna is presented based on enhanced microwave transmission to meet the needs of antenna gain in communications systems.The proposed antenna is simulated by high frequency simulation software Ansoft HFSS.The measured result shows that the gain of the proposed antenna is 12.9 dB,which is 6 dB higher than that of the conventional antenna.Moreover,due to the design of the annular aperture structure and the corrugated structure,the half power band width (HPBW) is increased by 100 degrees.The performance of the proposed antenna is improved significantly. |
