Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a 5G millimeter wave broadband antenna and a terminal. The 5G millimeter wave broadband antenna comprises: a dielectric substrate; a first antenna unit arranged on the dielectric substrate and working in a first frequency band; a second antenna unit arranged on the dielectric substrate and working in a second frequency band; and a third antenna unit arranged on the dielectric substrate and working in a third frequency band, wherein a second antenna unit power supply and the third antenna unit are respectively matched with the impedance of the first antenna unit. According to the invention, the first antenna unit, the second antenna unit and the third antenna unit are arranged on the dielectric substrate, so that the first antenna unit, the second antenna unit and the third antenna unit respectively work in three different frequency bands, the three different frequency bands are respectively controlled, full-band control of 5G signals is realized, the universality of the antenna is improved, and the design cost of the 5G millimeter wave broadband antenna is reduced.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a 5G millimeter wave broadband antenna and terminal. Background technique [0002] 5G millimeter wave technology has received a lot of attention since 2017. WRC-15 and before are mainly for frequency bands below 6 GHz, and WRC-19 is for frequency bands above 6 GHz. Referring to the global research and planning of high-frequency bands, the European Union completed the 26GHz frequency band planning in 2018, the United States completed the 28GHz (27.5-28.35GHz), 37GHz (37-38.6GHz) and 39GHz (38.6-40GHz) frequency bands, Japan and South Korea completed the 28GHz and 39GHz planning. China plans 26GHz and 37GHz frequency bands. That is, 26GHz to 39GHz is the mainstream millimeter wave frequency band in the world. The 3GPP protocol 38.101-2Table 5.2-1 defines three frequency bands for the 5G NR FR2 band, namely: n257 (26.5GHz~29.5GHz), n258 (24.25GHz~27.5GHz) and n260 (37GH...
