Abstract

This article presents low-profile wideband millimeter-wave (mmWave) end-fire antenna based on groundless grooved spoof surface plasmon polaritons (SSPPs) technique for applications in 5G mmWave communications. A novel linearly modulated grooved profile has been designed and optimized to convert bounded SSPP modes into radiation modes. The proposed groundless modulated grooved profile is designed to achieve a zero tilting and highly directional beam in the end-fire direction. A semi-curvilinear ground profile and stepped impedance transition profile are designed to improve impedance matching, which simultaneously enable wide bandwidth of 22 GHz to 41 GHz, i.e., fractional bandwidth (FBW) of 62% with a peak gain of 13 dBi in a low-profile structure. The overall form-factor of the antenna is 5 [Formula: see text] × 0.9 [Formula: see text] × 0.016[Formula: see text] (where [Formula: see text] is the wavelength in free space at the center frequency). The high directivity, low-profile and lightweight structure of the antenna makes it highly suitable for applications in mmWave communications.

摘要

本文提出了一种基于无接地开槽类表面等离子体激元（SSPPs）技术的低剖面宽带毫米波（mmWave）端射天线，用于5G毫米波通信应用。设计并优化了一种新型线性调制开槽轮廓，以将束缚的SSPP模式转换为辐射模式。所提出的无接地调制开槽轮廓旨在实现端射方向上的零倾斜和高定向波束。设计了半曲线接地轮廓和阶梯阻抗过渡轮廓以改善阻抗匹配，这同时在低剖面结构中实现了22 GHz至41 GHz的宽带宽，即62%的分数带宽（FBW），峰值增益为13 dBi。天线的整体外形尺寸为5 [公式：见正文] × 0.9 [公式：见正文] × 0.016[公式：见正文]（其中[公式：见正文]是中心频率下自由空间中的波长）。该天线的高方向性、低剖面和轻质结构使其非常适合毫米波通信应用。
