一种应用于手机中的WLAN三频带天线设计

内容简介：设计了一种满足WLAN三频带工作所需的微带天线。该天线的尺寸为7.5 mm×19 mm，与其他设计比较具有尺寸小、结构简单、易于加工的优点。仿真和实测结果表明，设计的天线10 dB阻抗带宽完全覆盖WLAN的2.4 GHz、5.2 GHz、5.8 GHz三个频带，同时天线也具有良好的辐射特性。对WLAN三频带天线的设计进行描述。

Abstract：A microstrip antenna with the size of 7.5 mm×19 mm is designed to satisfy the need of tri-band WLAN. Compared to other designs,the antenna has the advantages of small size,simple structure and easy to process. The simulated and mea-sured results show that the -10 dB impedance bandwidth of the antenna completely covers three bands of 2.4 GHz,5.2 GHz and 5.8 GHz of WLAN. The antenna also has good radiation characteristics. The design of the tri-band WLAN antenna is described.
