Abstract

A dual-sense circularly polarized (CP) array antenna with dipole elements is introduced in this study. The metallic elements, shaped like parentheses, mounted on the printed dipole, excite two CP modes with different polarizations by rotating at +45˚ and −45˚. Consequently, switchable polarizations of the antenna are available in the left-hand circular polarization (LHCP) and right-hand circular polarization (RHCP). According to the measured results, the proposed 4-element CP array antenna has impedance bandwidth with CP performance exceeding 20 % (11.83–14.47 GHz) and a peak gain of 14.55 dBic. The designed CP antenna has a low-profile with a compact dimension of 5.05λ × 1.51λ × 0.28λ which is suitable for satellite applications at Ku-band. This method is innovative, offering lower complexity and better results compared to conventional approaches.

一种带极化变换器元件的ku波段双感CP阵列天线

介绍了一种偶极元双感圆极化（CP）阵列天线。将圆括号形状的金属元件安装在印刷的偶极子上，通过在+45˚和- 45˚旋转激发出两种不同极化的CP模式。因此，可切换的天线极化左手圆极化（LHCP）和右手圆极化（RHCP）。实测结果表明，所设计的4元CP阵列天线的CP性能阻抗带宽超过20% (11.83 ~ 14.47 GHz)，峰值增益为14.55 dBic。所设计的CP天线外形小巧，尺寸为5.05λ × 1.51λ × 0.28λ，适合ku波段卫星应用。与传统方法相比，该方法具有创新性，复杂度更低，效果更好。
