摘要
设计了一种V形槽微带贴片天线,并通过HFSS软件对该结构的S参数、电压驻波比、辐射方向图进行了研究,结果表明该天线可以工作在5.1GHz~6.1GHz的频带,中心频率为5.5GHz。同时与具有相同尺寸的U形槽天线进行了对比,发现V形槽天线的带宽相对较宽,且增益相对较高,可达8d B。根据其特性,该结构可以应用于室内无线通信系统。
The V-shaped slot microstrip patch antenna is proposed in this paper, and the S parameters, VSWR and the radiation pattern are studied by HFSS. The antenna can work from 5.1GHz to 6.1GHz, the center frequency of the antenna is 5.5GHz. At the same time the U-shaped slot antenna of the same size is compared and the result shows that the bandwidth of V-shaped slot microstrip patch antenna is wider, and the gain is relatively high and up to 8d B. According to its characteristics, the structure can be applied to indoor wireless communication system.
