摘要

设计并制造了一种全金属宽带双极化维瓦尔第阵列天线。所提出的天线的结构包括谐振腔和直接接触接地平面的锥形散热片,允许连接巴伦和锥形散热片并减少天线长度。为了扩大频率范围,谐振腔宽度大于孔径长度的一半,并且锥形翅片的厚度不均匀。所提出的维瓦尔第阵列天线是在参数研究的基础上设计的。有源元件和阵列的增益范围为-2.9 dBi至6.4 dBi,在2–6 GHz的频率范围内为14.9至23.5 dBi。所提出的阵列天线在方位角方向上具有高达45°和仰角方向上具有25°的波束操纵能力。由于测量结果和模拟预测非常一致,因此所提出的阵列天线将适用于具有不同偏振要求的宽带宽波束控制系统。

Multiparametric Design of an All-Metal, Broadband, Slant Dual-Polarized Vivaldi Array Antenna
An all-metal, broadband, dual-polarized Vivaldi array antenna was designed and fabricated. The structure of the proposed antenna comprised a resonant cavity and tapered fins that contacted the ground plane directly, allowing the connection of a balun and tapered fins and reducing the antenna length. To extend the frequency range, the resonant cavity width is larger than half the aperture length, and the tapered fins have nonuniform thickness. The proposed Vivaldi array antenna is designed based on parametric studies. The gains of the active element and array ranged from -2.9 dBi to 6.4 dBi and 14.9 to 23.5 dBi in the frequency range of 2–6 GHz. The proposed array antenna exhibited beam steering capability up to 45° along the azimuth and 25° along the elevation angle directions. Since the measured results and simulated predictions were in good agreement, the proposed array antenna would be applicable for a broadband, wide-beam steering system with different polarization requirements.
