| 摘 要： | 对微带贴片天线频带展宽方面的研究做了全面、深入的探讨。主要介绍了几种新颖的大带宽微带贴片天线和天线阵。这些天线采用了在贴片或接地板“开窗”、附加负载、增加贴片元等方法来改进微带贴片天线的窄频特性。天线阵主要采用改进馈电网络的方法来展宽频带。这些方法使微带贴片天线向小型化、结构简单方向发展 ,从而使其应用范围进一步扩大。

| Abstract: | We discuss the research of the microstrip antenna in the aspect of bandwidth enhancement in detail. Some novel microstrip antennas with large bandwidth are introduced principally. The methods of cavity-backed microstrip patch or substrate, resistor loading and increasing the microstrip patches are used to improve the narrow bandwidth characteristics of the microstrip antenna. The method of improving the feed network is to broaden the bandwidth of the microstrip patch arrays principally. These methods make the microstrip antenna with smaller and simpler structure. So it broadens the implemented area of the antenna. |
