摘　　要：为了适应现代双频通信系统的要求,该文将褶皱结构的透波增强特性应用于天线设计中,并在中心圆孔处添加环形金属柱,设计了一个双频高增益天线。仿真和测试结果表明,在12.7 GHz和14.4 GHz处,天线的增益分别为12.0 dB和12.9 dB,相对于传统天线分别提高了5.6 dB和6.3 dB。此外,天线的半功率波束宽度(Half Power Beam Width,HPBW)也得到了较好的优化。In order to adapt to the requirement of the modern dual-band communication system, this paper presents a novel dual-band high gain antenna by adding an annular metal cylinder to the aperture in the center based on enhanced microwave transmission property of corrugated structure. Both the simulation and measurement results show that the gain of the proposed antenna is 12.0 dB and 12.9 dB at 12.7 GHz and 14.4 GHz separately, which is increased by 5.6 dB and 6.3 dB compared with the conventional antenna. Moreover, the Half Power Beam Width （HPBW） of the proposed antenna also gets much better.
