摘要
提供了一种实用的宽带圆极化微带天线的设计方法,采用微带线共面馈电,利用正交馈电的方法实现圆极化工作,并采用层叠结构,使上下两层贴片分别谐振于相近的频率,展宽其工作带宽。在此设计基础上制作了天线样机,实测阻抗带宽达到9.5%(VSWR≤2)。
A simple and practical method for the design of broad-band circularly polarized micro-strip antenna is presented in this paper. The antenna fed by micro-strip is realized by two stacked square patches. By orthogonal fed, the circularly polarized radiation can be obtained satisfactorily. Utilizing the two patches resonance at two close frequencies the bandwidth is broadened. Based on the above method the antenna for INMARSAT has been designed and realized. The measured results show that the proposed antenna impedance bandwidth is up to 9.5% （VSWR≤2）.
