Orthogonally Polarized MIMO LTE/5G Terminal Antennas for Handsets and IoT Applications

摘要

A broadband resonant terminal antenna has been developed for handsets and IoT applications. It can cover the whole LTE band (0.7-3.8GHz), or the 5G Sub6GHz band (3.3-7GHz) without using any matching/tuning circuits. It is covered with a thin dielectric layer to reduce its length. The new antenna does not depend on the ground plane of the terminal. It is manufactured from a thin flexible material that can be folded around the narrow sides of the terminal. This allows putting two antennas on two perpendicular sides of the handset with a high isolation between them because of the polarization diversity.
