摘要
为实现天线的小型化,设计了一种中心频率为2.4GHz的圆极化微带天线。该天线贴片上开对称凹槽,采用弯折的馈电方式,实现圆极化辐射特性。与普通微带天线相比,其辐射体的面积减小50%,圆极化轴比带宽为50MHz。天线结构简单,制作成本低。
In order to realize the miniaturization of the antenna,a circularly polarized microstrip antenna worked at the central frequency of 2.4GHz is designed for wireless communication.A set of slits and slots on the radiation patch are used to realize the miniaturization of the antenna.A bending microstrip line is used to achieve the circularly polarized characteristics.Compared with the common microstrip antenna,the area of radiator is reduced by 50%.The bandwidth of the circular polarization axis is 50 MHz.This antenna structure is simple and the production cost is low.
