Abstract

In this article, an extremely low-profile and broadband microstrip patch antenna is proposed for 5G mobile applications. By cutting two asymmetrical slots and loading additional metallic vias on the aperture-couped patch antenna, the TM₁₀ and anti-TM₁₀ mode are excited simultaneously to achieve the broadband operation with an extremely low-profile of 0.9 mm (0.013λ₀). A prototype of the proposed antenna was fabricated and tested, with the measured −6-dB bandwidth of 780 MHz (4.28–5.06 GHz), covering the 5G N79 band. The total efficiencies are between 65% and 85%. The proposed antenna provides a feasible solution for 5G mobile handset antenna on the back cover of the device.

用于5G智能手机的极低姿态宽带贴片天线

本文提出了一种用于5G移动应用的极低姿态宽带微带贴片天线。通过在孔径耦合贴片天线上切割两个非对称槽并加载额外的金属过孔，TM10和反TM10模式同时被激发，以0.9 mm （0.013λ0）的极低轮廓实现宽带运行。制作并测试了该天线的原型，测量到- 6 db带宽为780 MHz (4.28-5.06 GHz)，覆盖5G N79频段。总效率在65%到85%之间。该天线为5G手机后盖天线提供了一种可行的解决方案。
