摘要
提出了一种新型平面单极子微带天线阵,以平面矩形单极子天线为原型,通过改变辐射贴片的形状实现对原有天线性能的优化。设计了中心频率为2.4 GHz,相对带宽是42%,增益达13 dBi的宽频带四单元平面单极天线阵。通过仿真与实验表明,该天线在1.93 GHz^2.93 GHz频带内反射系数均小于-10 dB。
A miniaturized planar monopole microstrip array antenna is designed in this article.The antenna is based on the rectangle planar monopole antenna.By altering the figure of the radiation patch,the characteristic of antenna can be improved.And it also designs broadband array of plane monopole,in which the center frequency is 2.4 GHz,has a gain of 13 dBi and bandwidth is of 42%.Experimental results show that the reflectance is less than-10 dB in the work band from 1.93 to 2.93 GHz.
