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 microstrip antenna oper-ating 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 re-sults 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.
