Abstract

A novel 3-D printing ridge gap waveguide (RGW) wide-angle endfire dual-dipole multibeam antenna operating at millimeter-wave (mmW) frequency spectrum is proposed, which consists of an RGW

$6\times 6$

Butler matrix (BM) and an endfire dual-dipole antenna array. This article provides a detailed description of the working principle and design process of the

$6\times 6$

BM. By incorporating RGW technology, transmission losses of the beamforming network (BFN) are effectively reduced, which enhances the radiation efficiency of the final multibeam antenna. A modified endfire dual-dipole antenna with wide beamwidth is introduced. By integrating the

$6\times 6$

BM with the endfire dual-dipole antenna array, the final multibeam antenna is realized. This antenna provides a maximum scanning-plane half-power beamwidth (HPBW) coverage of ±83.5° and an associated gain varying from 12.3 to 13.8 dBi at 28 GHz. Furthermore, an analysis is conducted on the fabrication issues related to manufacture tolerance and surface roughness in 3-D printing processes, which evaluate the ability and accuracy of 3-D printing technology in mmW antenna applications.

提出了一种工作在毫米波（mmW）频谱下的新型3d打印脊隙波导（RGW）广角端射双偶极子多波束天线，该天线由RGW $6\ × 6$ Butler矩阵（BM）和端射双偶极子天线阵列组成。本文详细介绍了$6\ × 6$ BM的工作原理和设计过程。通过引入RGW技术，有效降低了波束形成网络（BFN）的传输损耗，提高了最终多波束天线的辐射效率。介绍了一种改进的端射双偶极子宽波束天线。通过将$6\ × 6$ BM与端火双偶极子天线阵列进行积分，实现了最终的多波束天线。该天线提供了±83.5°的最大扫描面半功率波束宽度（HPBW）覆盖范围，相关增益在28 GHz时从12.3到13.8 dBi不等。在此基础上，分析了3d打印工艺中与制造公差和表面粗糙度相关的制造问题，评价了3d打印技术在毫米波天线中的应用能力和精度。

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
