摘要

本文报道了一种具有独立波束控制的宽带双圆极化发射阵列（dual-CP TA）。基于惠更斯超表面元，采用自旋解耦双cp相位设计方法实现光束独立控制。多层级联提高了传输效率和相移范围。四种不同尺寸的元件提供180°的动态相位覆盖，元件旋转90°可实现180°的相位反转。采用2 × 2磁电偶极子天线作为馈源，使天线轮廓减小到4.5${{\lambda}_0}$。在20 GHz时，左手CP波和右手CP波的增益分别为21.5和21.2 dBic，峰值孔径效率分别为23.5%和22%。2db增益带宽（BW）和2db轴比（BW）分别优于13.9%和11.3%。

A Broadband Dual Circularly Polarized Transmitarray With Independent Beam Control

In this letter, a broadband dual-circularly polarized transmitarray (dual-CP TA) with independent beam control is reported. Based on Huygens’ metasurface elements, a spin-decoupled dual-CP phase design method is employed to achieve independent beam control. The transmission efficiency and phase shift range are enhanced by cascading multiple layers. Four distinct element sizes provide 180° of dynamic phase coverage, and a 90° rotation of the element enables a 180° phase reversal. A 2 × 2 magneto-electric (ME) dipole antenna is used as the feed, reducing the antenna profile to 4.5

${{\lambda }_0}$

. At 20 GHz, the measured gains of left-handed CP wave and right-handed CP wave are 21.5 dBic and 21.2 dBic, with peak aperture efficiencies of 23.5% and 22%, respectively. The 2 dB gain bandwidth (BW) and 2 dB axial ratio BW are superior to 13.9% and 11.3%, respectively.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
