用于Wi-Fi频段的新型双频天线设计

通过对实现双频技术的分析研究,设计了一种新型紧凑单馈的双频天线。该天线采用单层微带馈线和开缝接地板构成,分别印制在介质板2侧。天线的面积只有20×26 mm。天线的工作频段分别为2.40~2.53 GHz和5.00~5.96 GHz,同时,运用HFSS10电磁仿真软件对影响工作频率的参数进行了分析和研究。最后对制作的实物进行测试,测试结果与仿真结果基本吻合。提出的天线仅改变了接地板的结构就可实现具有小型化和双频段的特性,适用于无线通信领域。

Design of A Novel Dual-band Antenna for Wi-Fi Bands

A novel compact Single-Feed Dual-Frequency Patch Antenna is proposed in this paper. According to the analyses of characteristics of two operation bands, monolayer micro-strip-fed and slot-rectangle frame are adopted and separately printed on the opposite side of substrate in this antenna. The area of this antenna is only 20×26 mm. The operation bands of the antenna are from 2.40 GHz to 2.53 GHz and from 5.00 GHz to 5.96 GHz. Simultaneously the parameters that affect the operation frequencies are analyzed and studied by using EM simulation software HFSS10. Lastly, the antenna is fabricated and measured, and the measured results are in good agreement with the simulated results. The antenna proposed in this paper has the characteristics of miniaturization and dual-band, so it is suited for wireless communication field.
