摘要

本文提出了一种宽带双极化全双工天线阵列。该阵列由四个双极化维瓦尔第天线组成，通过改进馈电来获得正交极化之间的完全对称。该阵列由一个宽带4路平衡器馈电，该平衡器可以将输入信号分成四个相等幅度的输出信号，其中两个相对于另外两个进行相位反转。仿真结果表明，该阵列在2 GHz到20 GHz以上范围内匹配，平均增益为11 dBi。此外，在理想条件下，该阵列可以实现高水平的自干扰抵消(≥120 dB)，并且在实践中估计该水平优于40 dB。

Wideband Dual-Polarized Full-Duplex Antenna Array

In this paper, a wideband dual-polarized full-duplex antenna array is presented. The array is formed of four dual-polarized Vivaldi antennas with a modified feeding to obtain total symmetry between the orthogonal polarizations. The array is fed by a wideband 4-way balun that can split the input signal into four output signals of equal amplitudes with two of them being phase inverted with respect to the other two. The simulated results indicate that the array is matched from 2 GHz to beyond 20 GHz with an average gain of 11 dBi. Also, under ideal conditions, the array can achieve a high level of self-interference cancellation (≥ 120 dB), and this level is estimated to be better than 40 dB in practice.
