Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a schematic diagram of a conventional CPE antenna and an interconnection design, and as shown in fig. 1, the conventional CPE antenna includes a 5G CPE housing 10, a PCB board fixing device 20, a PCB board 30, a coaxial line 40 connected between the PCB board 30 and the CPE5G antenna 50, a CPE5G antenna 50 (in fig. 1, the number of CPE5G antennas is only schematic, and may be other numbers), a coaxial line socket 60 disposed on the CPE5G antenna 50, a coaxial line socket 70 disposed on the PCB board 30 (the structures of the coaxial line socket 60 disposed on the CPE5G antenna 50 and the coaxial line socket 70 disposed on the PCB board 30 may be the same), and a CPE WIFI antenna 80 (in fig. 1, the number of CPE antennas is only schematic, and may be other numbers).
Due to the fact that the number of the antennas in the 5G CPE is large, more advanced antenna and PCB interconnection design technology needs to be adopted. The 5G basic configuration is 4x4MIMO (multiple-in multiple out, which is an antenna system that uses multiple antennas at both the transmitting end and the receiving end to form multiple channels between transmitting and receiving, in order to greatly increase channel capacity), and requires 4 antennas for CPE and 4-8 antennas for WIFI, resulting in a larger number of antennas for 5G CPE. The interconnection transmission line between the 5GCPE antenna and the PCB mainboard needs a large number of coaxial lines (the coaxial line is a guide system formed by two coaxial cylindrical conductors, a broadband microwave transmission line of air or high-frequency medium is filled between an inner conductor and an outer conductor, the structure of the coaxial line sequentially comprises a sheath, an outer conductor layer, an insulating medium layer and an inner conductor from outside to inside, and the coaxial line is matched with a coaxial line seat for use). The frequency band adopted by the 5G technology is 3-5GHz at present, the 4G technology adopts the working frequency below 3GHz, and the working frequency of the 5G technology is much higher than that of the 4G technology. The WIFI 6 will also use 5GHz band of high frequency and 6GHz band of future in large amount. Therefore, in the stacked design of 5G CPE, the interconnecting transmission lines are staggered and often need to be folded due to the numerous antennas and limited space.
Because the existing antenna material and process adopted by the 5G CPE are mainly FPC and PCB or LDS process is applied to complete the antenna design, the antenna is designed into 5G and WIFI antennas (CPE 5G antenna 50 and CPE WIFI antenna 80 in figure 1) according to the antenna design requirement, then the CPE5G antenna 50 is connected with the PCB 30 by the coaxial line 40 through the PCB 30, the coaxial line seat 60 and the coaxial line seat 70, and therefore a large number of coaxial lines and coaxial line seats are needed.
The 5G antenna device in the invention uses LCP material, LCP (liquid crystal polymer) is a novel polymer material, and generally becomes a liquid crystal form under a certain heating state; have excellent properties, such as: excellent electrical properties (low dielectric loss at high frequencies), high temperature resistance, high strength mechanical properties, etc. LCP is used as a novel dielectric material, has the advantages of low dielectric loss and high working frequency, and is very suitable for application in the field of high-frequency signals. The 5G communication device uses a higher frequency signal, and has higher requirements for dielectric constant, dielectric loss, and the like of a material.
