双层宽频微带天线的设计防鸟刺作者：李旭哲,苏 桦,李 珣,刘 藤来源：《现代电子技术》2010年第21期 压力检测装置摘 要:微带天线的窄频带特性是限制其广泛应用的重要原因之一,因此机控网,如何展宽微带天线的带宽的问题一直受到研究人员的关注。通过采用双层多贴片及在两贴片之间加入空气层的结构来达到增加微带天线带宽的目的。此外,利用微带线进行正交馈电,放线菌培养基
在满足宽频带的同时,也实现了天线的圆极化。由贴片间的谐振耦合作用,该天线的频带展宽为11 04%(VSWR≤2),且增益达到了5 2 dB,可以在1 206~1 346 G的L波段内工作。 关键词:微带天线; 双层贴片; 宽频带; 圆极化

Abstract: The narrow bandwidth property of a micro-strip antenna is one of the important reasons to restrict its wide application, so how to broaden the bandwidth of micro-strip antenna has been the concern of the related researchers. Some methods to broaden the bandwidth of micro-strip antennas have been proposed in the past few years, and have achieved good effects.The double-layer patch is adopted and inserted between the two air-layer structures to implement the purpose of increasing the bandwidth of micro-strip antennas. In addition, the orthogonal feed is used to achieve a circular polarization of antennas. Since there is the function resonance coupling between the patches, the bandwidth of the micro-strip antenna is extended to 11.04% under the condition of VSWR≤2 and the gain reaches 5.2 dB. It can work well within L band from 1 206~1 346 GHz.
