Abstract

In this paper, a dual-band, dual-linearly polarized multibeam transmit-reflect-array (TRA) antenna is proposed. The dual-beams with different polarizations can be transmitted in the lower frequency band and reflected in the higher frequency band. The element comprises three metallic layers separated by substrate, enabling independent control of vertically and horizontally polarized waves in both the reflective and transmissive bands. Due to the frequency and polarization independence of the element, phase compensations are designed for vertically and horizontally polarized waves in each band, respectively. The circular aperture TRA is illuminated with a rotated linearly polarized horn, thereby generating dual-beams with different directions and polarizations in both the transmissive and reflective modes. The measurement results show that the peak aperture efficiency is 43.6 % and 36.0 % for the reflection band and transmission band. For the transmission band, the 3 dB gain bandwidths are 11.2 % (21–23.5 GHz) for horizontal polarization and 16.1 % (20–23.5 GHz) for vertical polarization. The 3 dB gain bandwidths for the reflection band are 12.1 % (27–30.5 GHz) for both the horizontal and vertical polarizations. The TRA antenna emerges as a promising contender for the implementation of bidirectional wireless communication.

具有独立波束控制的双频双线偏振多波束发射-反射阵列天线

本文提出了一种双频、双线极化多波束发射-反射阵列（TRA）天线。不同偏振的双光束可以在较低的频带传输，在较高的频带反射。该元件由基材分开的三个金属层组成，能够独立控制反射和透射波段的垂直和水平极化波。由于元件的频率和极化无关性，在每个波段分别对垂直极化波和水平极化波进行相位补偿。圆形孔径TRA用旋转的线偏振角照射，从而在透射和反射模式下产生不同方向和偏振的双光束。测量结果表明，反射带和透射带的峰值孔径效率分别为43.6 %和36.0 %。在传输波段，水平极化的3 dB增益带宽为11.2 %(21-23.5 GHz)，垂直极化的3 dB增益带宽为16.1 %（20-23.5 GHz）。在水平和垂直极化下，反射波段的3 dB增益带宽为12.1 %（27-30.5 GHz）。TRA天线是实现双向无线通信的有力竞争者。
