AI 中文摘要
本文设计并验证了一种非常紧凑的2×2宽带波束转向阵列，采用单锥天线，用于北约第三频段（1350-2400 MHz）战术通信，具备干扰抑制能力。该阵列尺寸仅为4×4×4 cm³，可方便地安装在空间有限的车辆等平台上。阵列已制造并测量，其干扰抑制能力通过最小方差无失真响应波束形成器和仅相位波束形成器在存在单个干扰源的情况下进行了研究。结果表明，所设计的天线阵列在信号与干扰角度间隔超过15°时，可将信噪比显著提升超过10 dB；在间隔大于43°时，在整个工作频段内可提升超过20 dB。
英文摘要
In this paper, a very compact 2 x 2 wideband beamsteering array with monocone antennas is designed and validated for NATO Band III (1350-2400 MHz) tactical communications with interference suppressing ability. The small 4 x 4 x 4 cm$^3$ size of the array enables placing it for example on vehicles with limited space. The array is manufactured and measured, and the interference suppressing capability thereof is studied with a minimum variance distortionless response beamformer and a phase-only beamformer in the presence of a single interferer. It is shown that the designed antenna array can significantly improve the signal-to-noise ratio over 10 dB for angles separated over 15$^\circ$ from the signal-of-interest, and over 20 dB for separation larger than 43$^\circ$ across the operational band.
