摘要/Abstract

摘要： 针对微小型无线设备的无线局域网天线,在20 mm×20 mm的FR4介质基板上设计了一款5 mm×5 mm的微型贴片天线. 该天线的正面除了有U形辐射结构外,还添加了一端接地一端开路的2条一字形加载单元;天线反面的结构为正面加载单元的镜像,采用正面微带馈电方式. 实验结果显示,天线在2.4~2.483 5 GHz频带内具有良好的辐射特性,其电压驻波比能满足工程应用的需求,具有结构简单、紧凑,成本低且便于与有源电路集成的优点.

Abstract: To develop wireless local area network (WLAN)antennas for micro-small wireless devices, a 5 mm×5 mm micro patch antenna is designed on a 20 mm×20 mm FR4 dielectric substrate. In addition to the U-shaped radiation structure on the front of the patch antenna, two in-line loading units with one end grounded and the other open are added, while the reverse structure of the patch antenna is a mirror image of the front loading unit. Besides, the front micro-strip feeding method is adopted. The experimental results show that the antenna has good radiation characteristics in the 2.4~2.483 5 GHz frequency band, and its voltage standing wave ratio satisfies the requirements of miniaturized antenna engineering applications. Besides, the antenna has the advantages of simple and compact structure, low cost and easy integration with active circuits.

Key words: miniaturized, patch antenna, loading unit, voltage standing wave ratio
