Abstract

This study introduces a multi-functional antenna array concept with polarization and phase-out reconfigurability operating in the Ka-band. We propose a novel dual-polarized reconfigurable antenna element featuring 1-bit phase quantization functionality using p-i-n diodes. The element comprises four p-i-n diodes on one symmetrical metallic layer and two bias lines for controlling four main outgoing wave modes. This single antenna offers a bandwidth of 1 GHz in four modes at 27 GHz, along with approximately 180 ° phase conversion for both linear polarization (LP) states. We construct 4 × 4 a multi-functional array with the arrangement of mirroring elements technique to suppress the cross polarization without the requirement for an external phase-shift compared to conventional dual-port method. Measurement results show a peak gain of 14.1 dBi with the XPD of 24 dB. Additionally, we show beam-steering capability

双线极化ka波段天线阵列中基于P-I-N二极管的混合模式可重构元件天线

本文介绍了一种工作在ka波段的具有极化和相位可重构性的多功能天线阵列概念。我们提出了一种新型的双极化可重构天线元件，采用p-i-n二极管，具有1位相位量化功能。该元件包括一个对称金属层上的四个p-i-n二极管和两条用于控制四个主要输出波模式的偏置线。这种单天线在27 GHz的四种模式下提供1 GHz的带宽，并在两种线性极化（LP）状态下提供大约180°的相位转换。与传统的双端口方法相比，我们采用镜像元件排列技术构建了4 × 4多功能阵列来抑制交叉极化，而不需要外部相移。测量结果表明，峰值增益为14.1 dBi， XPD为24 dB。此外，我们还展示了该天线元件在与仅提供连续180°相移的波束形成器结合时的波束转向能力±30°。
