摘要

本文针对 5G 应用提出了一种新型天线。该天线的尺寸为 (32×32×0.8) mm³。所建议的天线建立在 FR-4 环氧介质基板上，其损耗正切为 0.025，介质的相对介电系数为 4.3，在该基板的顶层蚀刻了具有特定尺寸的多边形贴片，还在基板的底层建立了接地平面。天线的贴片由特性阻抗为 50Ω 的微带馈电线馈电。拟建天线的谐振频率为 3.6 GHz，带宽为 (3.15 - 4.3) GHz，工作频率下的增益为 (3.3) dBi，这些特性适用于 5G 应用。为了达到目标带宽和增益，在贴片和地平面上都刻了不同的槽。仿真结果使用 CST-MW 2020 收集。

DESIGN AND ANALYSIS OF MICROSTRIP ANTENNA FOR 5G APPLICATIONS

A new proposed antenna is presented in this article for 5G applications. The dimensions of this antenna are (32×32×0.8) mm³. The antenna that is suggested is built upon FR-4 epoxy dielectric substrate, with a loss tangent of 0.025 and relative permittivity of dielectric is 4.3 and, on the top layer of this substrate a polygon patch is etched with specific dimensions, also a ground plane on the bottom layer of the substrate is built. The patch of the antenna is fed from a microstrip feed line with a 50Ω characteristic impedance. The proposed antenna operates at 3.6 GHz as a resonance frequency with a bandwidth of (3.15 - 4.3) GHz, and gain (3.3) dBi at the operating frequency, these characteristics are suitable for 5G applications. To attain the targeted bandwidth and gain, distinct slots are carved onto both the patch and ground plane. The simulation outcomes are gathered using CST-MW 2020.
