Abstract

Millimeter wave (mm-Wave) wireless communication systems require high gain antennas to overcome path loss effects and thereby enhance system coverage. This paper presents the design and analysis of an antenna array for high gain performance of future mm-wave 5G communication systems. The proposed antenna is based on planar microstrip technology and fabricated on 0.254 mm thick dielectric substrate (Rogers-5880) having a relative permittivity of 2.2 and loss tangent of 0.0009. The single radiating element used to construct the antenna array is a microstrip patch that has a configuration resembling a two-pronged fork. The single radiator has a realized gain of 7.6 dBi. To achieve the gain required by 5G base stations, a 64-element array antenna design is proposed which has a bore side gain of 21.2 dBi at 37.2 GHz. The 8 × 8, 8 × 16, and 8 × 32 antenna array designs described here were simulated and optimized using CST Microwave Studio, which is a 3D full-wave electromagnetic solver. The overall characteristics of the array in terms of reflection-coefficient and radiation patterns makes the proposed design suitable for mm-Wave 5G and other communication systems.

摘要

毫米波（mm-Wave）无线通信系统需要高增益天线来克服路径损耗效应，从而增强系统覆盖范围。本文提出了一种用于未来毫米波 5G 通信系统的高增益性能的天线阵列的设计和分析。所提出的天线基于平面微带技术，并在介电常数为 2.2、损耗正切为 0.0009 的 0.254 毫米厚的介质基板（罗杰斯 5880）上制造。用于构建天线阵列的单个辐射元件是具有类似于双叉形状的微带贴片。单个辐射器的实现增益为 7.6 dBi。为了实现 5G 基站所需的增益，提出了一种 64 单元阵列天线设计，在 37.2 GHz 时具有 21.2 dBi 的孔径侧增益。本文描述的 8 × 8、8 × 16 和 8 × 32 天线阵列设计使用 CST 微波工作室进行了模拟和优化，CST 微波工作室是一种 3D 全波电磁求解器。阵列在反射系数和辐射模式方面的整体特性使得所提出的设计适用于毫米波 5G 和其他通信系统。
