摘　　要：基于目前对WSN(无线传感器网络)的需求,本文设计了一种工作在2.4GHz的小型化的矩形开槽微带贴片天线,由于采用了曲流技术,该天线比一般微带天线要小,当工作在2.4GHz时,其导波波长为70mm,天线尺寸为29mm×29mm,长宽均为导波波长的0.4倍。仿真与测试结果表明,实验结果与仿真结果基本吻合。天线的-10dB带宽为24MHz(2.38GHz-2.404GHz),天线的辐射特性较好,在-10dB带宽内,辐射增益均大于0dBi,而且在中心频率2.4GHz处达到最大值6dBi。Based on the demand for WSN, one type of compact antenna is designed. A square mierostrip antenna operating at 2.4 GHz is presented. The size of the antenna is reduced largely because of effectively increasing of the current path, and the dimension of realized antenna is 29mm × 29mm.Good agreement between the simulated and measured results has been achieved. The bandwidth of the antenna reaches up to 2.38GHz-2.404GHz for S11〈-10dB, the gain of proposed antenna is larger than 0dBi from 2.35GHz to 2.45GHz, and even 6dBi at 2.4GHz.
