AI Technical Summary

Technical Problem

Existing antennas cannot work in the microwave and millimeter wave bands at the same time, lacking the effect of large frequency ratios, and cannot meet the multi-frequency communication needs of smart devices.

Method used

A multi-port large frequency ratio antenna is designed, through the combination of metal floor and dielectric substrate, and the E-shaped metal patch and Vivaldi antenna unit are used to form an integrated structure of dipole antenna unit and Vivaldi antenna unit to realize dual-frequency operation in microwave and millimeter wave bands.

Benefits of technology

It realizes the ability of antennas to work simultaneously in the microwave band (such as WIFI band) and millimeter wave band (such as 5G band), covering the commonly used WIFI, Bluetooth and 5G communication bands to meet the multi-frequency communication needs of smart devices.

Abstract

The invention discloses a multi-port large-frequency-ratio antenna, which comprises a metal floor and a dielectric substrate, the surface of the dielectric substrate is connected with metal patches, the metal patches comprise a first metal patch and a second metal patch, the first metal patch and the second metal patch are E-shaped patches, and the first metal patch and the second metal patch are E-shaped patches. The antenna comprises an E-shaped patch, each antenna comprises a first branch and a second branch which are located in the center of the E-shaped patch, the first branch is provided with a first Vivaldi antenna unit, the second branch is provided with a second Vivaldi antenna unit, and the antenna further comprises a third Vivaldi antenna unit and a fourth Vivaldi antenna unit. The dipole antenna unit and the four Vivaldi antenna units are integrated, the dipole antenna unit has two different resonance paths due to the specific shape of the dipole antenna unit, double-frequency work is achieved in a microwave frequency band, the four Vivaldi antennas work in a millimeter wave frequency band, and the antenna can work in the microwave frequency band and the millimeter wave frequency band at the same time. The effect of a large frequency ratio is achieved, and common WIFI, Bluetooth and 5G communication frequency bands are covered.
