| 摘 要： | 针对毫米波段微带天线频带窄,馈电对天线辐射影响严重等缺点,提出了一种新型天线单元结构.该单元采用H型槽耦合馈电和增加寄生贴片的方法,实现了天线带宽的增加.此方法可使得带宽达到11%(VSWR<2).通过采用多层寄生贴片对单元进一步改进研究,验证了该单元具有进一步展宽带宽和作为天线罩保护天线的作用,天线的带宽可达到22%.

| Abstract: | The traditional millimeter-wave microstrip antenna having a narrow band and causing the severe influence on radiation of antennas by feeding of antennas,a novel antenna element is designed.The bandwidth of the antenna is increased by using the feeding style of a H-shaped coupling slot and adding the parasitic patch.The bandwidth of the antenna is about 11%(VSWR<2).Then,the new structure of the multi-layer parasitic patch element is proposed which expands the bandwidth of the antenna to 22%.It can be used to apply the protection to the antenna and to enhance the antenna bandwidth. |
