AI Technical Summary

Technical Problem

Existing vehicle antenna designs face challenges in terms of space and performance requirements, especially when integrating multiple high-frequency, multi-mode antennas, where traditional antennas are tall and difficult to achieve effective isolation and efficient radiation.

Method used

A low-profile, highly integrated 5G antenna module is designed. By setting a GPS antenna and a 5G and WIFI antenna in a circle around it on the main PCB board, connecting them with specific isolation angles and feed points, and forming multiple resonant points by combining multiple metal radiators and branch folds, the isolation and radiation performance are optimized by independent isolators and physical gaps.

Benefits of technology

It achieves an antenna height of less than 40mm and an efficiency of over 40% across all frequency bands. The isolation and radiation performance of the five frequency bands are significantly improved, especially the isolation of the low-frequency band is significantly optimized, meeting the requirements of high integration and high performance.

Abstract

This invention is a low-profile, highly integrated 5G antenna module, comprising a metal ground plane, a main PCB board, a GPS antenna positioned at the center of the main PCB board, and several groups of 5G antennas and Wi-Fi antennas arranged in a circle around the GPS antenna. The 5G antennas are spaced at a certain angle and are arranged in a circle adjacent to the GPS antenna; the Wi-Fi antennas are positioned between the 5G antennas and arranged in a circle away from the GPS antenna. This invention achieves an antenna height of less than 40mm through radiator folding, grounding optimization, a ring layout, and isolation design. Under a large-area metal ground plane, the 5G antenna achieves a full-band efficiency of over 40%, maintains high isolation even with multiple antennas close together, and supports full-band LTE, 5G NR, and FR1 band antennas with a very low antenna height. It also supports high-speed Wi-Fi and GPS tri-band positioning, making it highly suitable for intelligent connected vehicle antenna scenarios, offering advantages such as low profile, high integration, high performance, and high isolation.
