Problems solved by technology

However, from the perspective of aesthetics and cost, the space left for the antenna is not particularly abundant. It is very difficult to achieve such a wide-band performance with the existing antenna routing method and to ensure relatively high efficiency. Even The performance can meet the customer's needs, but the volume exceeds the space reserved by the customer

Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0024] Wherein, the accompanying drawings are only for illustrative purposes, showing only schematic diagrams, rather than physical drawings, and should not be construed as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the accompanying drawings will be omitted, Enlarged or reduced, does not represent actual product size.

[0025] refer to figure 1 with figure 2 A 5G full-band miniaturized PCB antenna shown includes an upper housing 10 and a lower housing 11. The upper housing 10 is sealed and fixedly connected to the lower housing 11 by several bolts, which can prevent internal components from sticking. A dielectric substrate 1 is fixed between the upper casing 10 and the lower casing 11, a radiator part 7 is fixed on the dielect...

Abstract

The invention relates to the technical field of 5G antennas, particularly to a 5G full-band miniaturized PCB antenna. According to the invention, a radiator part is fixedly arranged on a dielectric substrate; a transmission line part is fixedly arranged on the dielectric substrate; the side, away from the radiator part, of the transmission line part is fixedly provided with a signal bonding pad and a grounding bonding pad; the dielectric substrate is provided with an antenna grounding wire; the side, away from the radiator part, of the transmission line part is fixedly provided with a coaxialcable; and the end, away from the transmission line part, of the coaxial cable is fixedly connected with a radio frequency connector. A full-PCB structure is used, so an area is small, good universality is obtained, and good performance and practicability are achieved no matter the antenna is used as a built-in antenna or used as an internal structure of an external antenna; in addition, the structure of the antenna is simple; and a PCB is a common FR4 board, and utilization can be realized only by welding the corresponding coaxial cable and the radio frequency connector, so process is simple,cost is low, performance is excellent, a reject ratio is very low, and the PCB antenna is suitable for batch production.

Description

technical field [0001] The invention relates to the technical field of 5G antennas, in particular to a 5G full-band miniaturized PCB antenna. Background technique [0002] With the increasing demand for 5G, there are more and more requirements for the frequency band of the antenna, covering 600MHz to 6000MHz. In order to obtain better radiation performance, the size of the antenna will also increase accordingly. However, from the perspective of aesthetics and cost, the space left for the antenna is not particularly abundant. It is very difficult to achieve such a wide-band performance with the existing antenna routing method and to ensure relatively high efficiency. Even The performance can meet the customer's needs, but the volume exceeds the space left by the customer. [0003] Therefore, it has become an urgent need to develop a high-performance antenna with a small size that can cover from 600MHz to 6000MHz. Contents of the invention [0004] The purpose of the prese...
