摘要

本文设计了一种具有大跨度余割分布方向图的新型波束形成贴片阵列天线。该天线分为两层，在顶层的上表面设计了8个辐射贴片单元和馈电微带分支。底层是基板集成波导（SIW），其上壁上有一系列狭槽，将SIW中的能量耦合到馈电微带分支。首先设计5个线性阵列产生不同辐射角的波束，然后通过加权方式映射成一个复合阵列，产生大跨度的余切分布方向图，使天线尺寸最小化。该天线可在长直受限空间内提供均匀的无线电波覆盖，实现稳定的移动通信。

Design of Large-Span Beamforming Antenna Based on Beam Superposition and Structure Mapping

In this letter, a novel beamforming patch array antenna with large-span cosecant-distribution pattern is designed. The antenna contains two layers, and eight radiating patch elements together with feeding microstrip branches are designed on the upper surface of the top layer. The bottom layer is a substrate-integrated waveguide (SIW) with a series of slots cut in the upper wall, which couple the energy in SIW up to the feeding microstrip branches. Five linear arrays are designed first to generate beams with different radiation angles, and then mapped into a composite array in a weighted way to generate a large-span cosecant-distribution pattern, and minimize the size of antenna. The proposed antenna can provide a uniform radio wave coverage in long-straight confined spaces for stable mobile communications.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
