摘　　要：目前无线通信中的天线设计需要满足通信终端日趋小型化的要求.本文提出了一种新型的适用于无线通信系统的小型微带天线.该天线同时采用贴片左右对称曲流和接地板蚀刻梳状缝隙两种小型化方法,使其尺寸大大减小.测试结果表明,该天线在回波损耗时的工作带宽可达到2.415GHz～2.47 GHz,同时具有较好的辐射增益,是一种具有很好理论参考意义与实用价值的微带天线.Design of antennas in wireless communication systems need to satisfy the demand of communication terminal＇ s minimization. A novel compact microstrip antenna for wireless communication systems was proposed in this paper. Two methods, eudipleural meander on the patch and pectinate slot etched on the ground, were used simultaneously, which reduced the dimension of this antenna greatly. The result shows that the bandwidth of the antenna reaches up to 2. 415 GHz--2.47 GHz for return loss S11 〈 - 10 dB. Meanwhile, good radiation gain has also been achieved. This kind of microstrip antenna can be determined as a useful candidate for application.
