Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0031] Such as figure 1 As shown, the antenna in this embodiment includes a substrate 1 , a low-frequency vibrator 2 and a mid-high frequency vibrator 3 . Both the low-frequency vibrator 2 and the mid-high frequency vibrator 3 have a symmetrical structure with the axis of the substrate 1 as the center line; the low-frequency vibrator 2 forms a central feeder 6 along the center line toward the mid-high frequency vibrator 3; The electric point 4 is the signal point; the mid-high frequency vibrator 3 is provided with a grounding point 5 on its center line; the mid-high frequency vibrator 3 has a concave cavity 31 that can accommodate the center feeder 6; the center feeder 6 matches the concave cav...

Abstract

The invention discloses a broadband 5G antenna. The antenna comprises a substrate, a first radiation oscillator and a second radiation oscillator; both the first radiation oscillator and the second radiation oscillator are of a symmetrical structure taking the axis of the substrate as the center line; a central feeder line is formed in the direction, facing the second radiation oscillator, of thefirst radiation oscillator along the central line, and a feeding point is arranged at the tail end of the central feeder line; the second radiation oscillator is provided with a grounding point on thecentral line and is provided with a concave cavity capable of accommodating the central feeder line; and in an area where the central feeder line is matched with the concave cavity, at least one section of area of the central feeder line and / or the concave cavity is different from other areas in width. The broadband 5G antenna is wide in bandwidth, not only meets the domestic 5G high-frequency requirement, but also can well meet the requirements on low-frequency and medium-frequency bandwidth performance, can be universally applied to 2G / 3G / 4G / 5G / GPS / WIFI frequency bands, and can be compatible with all home and abroad operator frequency bands of sub-6G.

Description

technical field [0001] The present invention relates to an antenna, in particular to a broadband 5G antenna. Background technique [0002] As 5G technology becomes more and more mature, it has gradually spread into our daily life and work. In 2017, the Ministry of Industry and Information Technology of China has determined the 5G frequency band, namely 3.3-3.8G / 4.4G-4.8G. The 5G network is the fifth-generation mobile communication network, and its peak theoretical transmission speed can reach 10Gb per second, which is hundreds of times faster than the transmission speed of the 4G network. The goals of 5G performance are high data rates, reduced latency, energy savings, cost reductions, increased system capacity and large-scale device connectivity. In this way, there is no doubt that the antenna will naturally become the carrier of the Internet of Everything, and play the role of transmitting and receiving signals. [0003] Since 5G has added a high-frequency band and the ...
