摘要
对适用于毫米波相控阵的单馈点电磁结构的圆极化贴片天线单元进行了系统设计。该设计对轴比、阻抗带宽和轴比带宽折衷考虑,取得了21.4%的阻抗带宽,6.6%的3 dB轴比带宽,带宽内最高增益值为7.5 dB,满足了设计要求。
This paper presents a systematic design for a singly-fed electromagnetically coupled patch antenna element for circular polarization. It is suitable with the millimeter-wave phased array. The investigation reveals tradeoffs amongst obtainable AR, impedance bandwidth and AR bandwidth. A 21.4% impedance bandwidth and a 6.6% of 3 dB AR bandwidth have been obtained with a peak gain of 7.5 dB.
