提出了一种新型宽带微波圆极化天线结构。该阵列天线由四个单元的三单元平面天线组成。该单元天线由接地平面上的馈电和电抗元件的三个圆形元件组成。单元天线由接地单元上的馈电单元和电抗单元组成。馈电元件由在两侧截断的圆盘制成，以分离较高和较低频率（fH和fL）的产生。上述天线的四个单元应用于正交阵列天线。两种类型的空间安排与四个单元天线给出了单独的路由线电路。与传统的平行排列的2.2 ~ 2.4%的带宽相比，圆极化的宽带特性得到了10%的极宽带宽。这个结果是由具有三个元件的单元天线的原始配置带来的。关键词-退化分离，圆极化，轴比，三元结构。
This paper presents novel configuration of wideband microwave circular polarization antenna. This array antenna is composed of four units of three elements plane antennas. This unit antenna is composed of three circular elements of feed and reactance elements on a ground plane. The unit antenna is composed of a feed and a reactance elements on a ground element. The feed element is made of a disc truncated at both sides to separate generation of higher and lower frequencies (fH and fL), Four units of the above antenna are applied to the orthogonal array antennas. Two types of spatial arrangements with four unit antennas are given with individual routing wire circuits. Wideband characteristics of circular polarization are achieved extremely wide bandwidth 10% compared to 2.2 ~ 2.4 % bandwidth by conventional parallel arrangements. This result was brought by the original configuration of the unit antenna with three elements. Keywords— Separation of degeneration, Circular polarization, Axial ratio, Three-element-structure.
