Antenna module and terminal

Abstract

The invention discloses an antenna module and a terminal using the antenna module. The antenna module comprises an antenna array and a radio frequency phase shift system, wherein the antenna array iscomposed of a plurality of antenna units, and the antenna array and the radio frequency phase shift system are integrated on a circuit substrate to form an independent module. Furthermore, the antennaunits of the antenna module can adopt a scheme that a microstrip patch antenna structure is loaded with a short circuit column to generate a plurality of resonances, so the bandwidth of the antenna units is expanded, and after an antenna array is formed, the antenna modules can be further arranged in a mutually vertical arrangement manner to realize the functions of large-angle scanning and polarization diversity. The antenna module disclosed by the invention is simplified in structure, can be applied to 5G communication, and has the advantages of easiness in system integration, low profile miniaturization, relatively wide radiation bandwidth and capability of realizing large-angle scanning.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an antenna module and a terminal. Background technique [0002] With the development of wireless communication technology, terminal devices such as mobile phones, tablet computers, and portable multimedia players have become indispensable necessities of life. The terminal device is usually equipped with an antenna module to transmit and receive wireless signals, so as to support the wireless communication function of the terminal device. [0003] Today, 5G (fifth-generation mobile communication technology) is the focus of current research and development, and the development of 5G has become a consensus in the industry. Among them, due to the unique characteristics of high carrier frequency and large bandwidth of millimeter wave, it is the main means to achieve 5G ultra-high-speed data transmission rate. .

AI Technical Summary

Problems solved by technology

At present, most 5G millimeter-wave antenna modules for terminals adopt the AOB (antenna on board) scheme, that is, the antenna array is arranged on the side of the terminal, and the radio frequency circuit part (such as the radio frequency phase shifting system) is integrated on the main board (main board) ), so that the array and the radio frequency circuit are arranged separately, and cannot be integrated into a module that works independently

In other prior art solutions, although the beam bandwidth of the antenna is improved, and the large-angle scanning of the antenna array can be realized, however, due to the need to adopt more complex multi-resonant structures and materials with low dielectric constants, the antenna's The profile is high, it is difficult to realize integrated application
