A wide band circularly polarized (CP) aperture coupled staircase shaped wideband dielectric resonator antenna (SSCPDRA) array is implemented. The proposed array is composed of identical four SSCPDRA elements. The wideband CP and gain of the single element is enhanced by using 2 × 2 array with sequential phase feeding network. The measured results outputs emphasize that the proposed array is operated at frequency band from 8 to 12.3 GHz (43%). In addition, it has 3 dB axial ratio extended from 8.35 to 12.2 GHz (38.5%). Furthermore, the radiation pattern has broadside direction with the usability within the X‐band applications.

一系列阶梯形圆极化DRA

实现了宽带圆极化（CP）孔径耦合阶梯形宽带介电共振器天线（SSCPDRA）阵列。提议的数组由相同的四个SSCPDRA元素组成。通过使用具有顺序相位馈电网络的2×2阵列，可以提高单个元件的宽带CP和增益。测量结果输出强调了所提出的阵列在8至12.3 GHz（43％）的频带下工作。此外，它具有3 dB的轴向比率，从8.35 GHz扩展到12.2 GHz（38.5％）。此外，辐射图具有宽广的方向，具有X波段应用程序中的可用性。
