Along with the development of intellectualization, miniaturization, security and multifunctionality of mobile communication equipment, new requirements are also put forward on antennas of mobile communication equipment, and the antennas are used for mobile communication equipment such as mobile phones and notebook computers, so that the antennas are required to meet the requirements of communication frequency, and are also required to have good received signals, high sensitivity and good heat dissipation performance, and therefore, development of a new antenna is needed.
Currently, two main current smart terminal antenna implementations in the market are realized, one is to use a flexible printed circuit board, and the other is to use a laser direct molding technology. The flexible printed circuit board is made of polyimide or polyester film as a base material and has the characteristics of high wiring density, light weight, thin thickness and good bending property. The flexible electronic device can move and stretch freely in a three-dimensional space, has good heat dissipation performance, can reduce the volume by using the FPC, and realizes light weight, miniaturization and thinness, thereby achieving the integration of element devices and wire connection.
The FPC antenna is equivalent to pulling out the antenna circuit on the PCB board, and other external metals are used for making the antenna.

The FPC antenna has the advantages that the FPC antenna is suitable for almost all small electronic products, can be used as a complex antenna with more than ten frequency bands like 4G, has good performance, and is easy to adhere to an arc-shaped and irregular plane due to good flexibility of the FPC. The cost is also relatively low.
However, it was found in the production process that the metal and magnetic materials affect the antenna transmission efficiency of the FPC antenna, resulting in an inefficiency of the antenna transmission. Along with the increasing number of intelligent products of wireless control, intelligent devices using FPC antennas are also more and more, and when FPC antenna structure design is carried out, antenna coaxial lines are more and more routed in the device, so the assembly difficulty of the products can be increased, and the path control difficulty of the coaxial lines is increased.
The application is applicable to all electronic equipment using FPC antennas, including intelligent gateway, intelligent home products, wireless remote control toys, smart devices such as cell-phones.
In order to solve the above technical problems, the present utility model provides a connection device for FPC antenna and motherboard, as shown in fig. 1, comprising:
a first FPC antenna 11, a second FPC antenna 12, and a main board 13;
the first FPC antenna 11 is arranged on the upper cover of the main board 13 and is connected with the main board 13; the second FPC antenna 12 is connected with the first FPC antenna 11 through the coaxial line 14 and is disposed on the upper cover of the main board 13, wherein the antenna transmission efficiency of the location where the second FPC antenna 12 is disposed is higher than the antenna transmission efficiency of the location where the first FPC antenna 11 is disposed.
The present embodiment refers to the motherboard 13, which is also called a motherboard (main board), a system board (system board), or a motherboard (atherboard); it is installed in the case and is one of the most basic and important components of microcomputer. The motherboard 13 is a generally rectangular circuit board on which the main circuitry that constitutes the computer is mounted, and typically has elements such as a basic Input/Output system (Basic Input Output System, BIOS) chip, an Input/Output (I/O) control chip, a keyboard and panel control switch interface, a pilot lamp connector, an expansion slot, a dc power supply connector for the motherboard 13 and a card.
The first FPC antenna 11 and the second FPC antenna 12 are both disposed on the upper cover of the motherboard 13, and the embodiment is not limited in the manner of setting, and may be set according to specific design requirements. The specific structure type of the FPC antenna is not limited, and the FPC antenna is selected according to actual application requirements.
The antenna transmission efficiency of FPC antennas is affected by a variety of factors, and the presence of metallic materials near the antenna results in the antenna efficiency being absorbed by the metallic or magnetic materials, which can interfere with the radiation of the antenna.
In this embodiment, the first FPC antenna 11 is connected to the motherboard 13, and the second FPC antenna 12 is connected to the first FPC antenna 11 through the coaxial line 14, wherein the antenna transmission efficiency at the position where the second FPC antenna 12 is disposed is higher than the antenna transmission efficiency at the position where the first FPC antenna 11 is disposed. When the antenna transmission efficiency of the first FPC antenna 11 is not ideal, the antenna transmission efficiency of the second FPC antenna 12 at the position where the first FPC antenna 11 is disposed is better than the antenna transmission efficiency of the second FPC antenna 12 through the connection of the coaxial line 14 to the second FPC antenna 12.
Coaxial line 14 is a line system consisting of two Coaxial cylindrical conductors, and is a wideband microwave transmission line in which air or a high-frequency medium is filled between the inner and outer conductors. Generally, the outer conductor of the coaxial line 14 is grounded, and an electromagnetic field is defined between the inner and outer conductors, so that the coaxial line 14 has substantially no radiation loss and is hardly interfered by external signals. The structure of the coaxial line 14 is composed of four parts, namely a sheath, an outer conductor layer, an insulating medium layer and an inner conductor, from outside to inside.
According to the connection device of FPC antenna and mainboard that this embodiment provided, include: a first FPC antenna 11, a second FPC antenna 12, and a main board 13; the first FPC antenna 11 is arranged on the upper cover of the main board 13 and is connected with the main board 13; the second FPC antenna 12 is connected with the first FPC antenna 11 through the coaxial line 14 and is disposed on the upper cover of the main board 13, wherein the antenna transmission efficiency of the location where the second FPC antenna 12 is disposed is higher than the antenna transmission efficiency of the location where the first FPC antenna 11 is disposed. When the antenna transmission efficiency of the first FPC antenna 11 is not ideal, the first FPC antenna is connected to the second FPC antenna 12 through the coaxial line 14, the antenna transmission efficiency of the second FPC antenna 12 at the setting position is better than that of the first FPC antenna 11, and the coaxial line 14 is used for covering the main board 13, so that the assembly difficulty is effectively reduced.
According to the above embodiments, the antenna should be located as far away as possible from the metal, magnetic material (magnets, batteries), any metal and magnetic containing material will have an effect on the antenna layout. The embodiment provides a specific scheme, in which the connection device between the FPC antenna and the motherboard is that the headroom area of the setting position of the second FPC antenna 12 is larger than the headroom area of the setting position of the first FPC antenna 11.
The clearance area is an area of irrelevant parts such as metal elements, isolation batteries, oscillators, shielding covers, cameras and the like which are not arranged around the antenna of the main board 13 and in a projection plane of the antenna perpendicular to the main board 13, and the non-clearance area is an area of the main board 13 which does not meet the definition of the clearance area.
In this embodiment, the headroom area of the second FPC antenna 12 at the position where it is disposed is larger than the headroom area of the first FPC antenna 11 at the position where it is disposed. When the clearance area of the first FPC antenna 11 is too small, and the antenna transmission efficiency is not ideal, the antenna is connected to the second FPC antenna 12 through the coaxial line 14, the clearance area of the setting position of the second FPC antenna 12 is larger than the clearance area of the setting position of the first FPC antenna 11, and the travelling wire is covered on the main board 13 through the coaxial line 14, so that the assembly difficulty is effectively reduced.
According to the above embodiment, the present embodiment provides a preferred solution, and the connection device between the FPC antenna and the motherboard, and the first FPC antenna 11 is connected to the motherboard 13 through the antenna thimble.

The antenna thimble is generally applied to precise connection in electronic products such as mobile phones, communication, automobiles, unmanned aerial vehicles, intelligent robots, aerospace and the like, and can improve the corrosion resistance, stability and durability of the connector. The antenna thimble has the characteristics of small volume, high current resistance, long service life, water resistance and the like. The first FPC antenna 11 of the present embodiment is connected to the motherboard 13 through an antenna thimble, so as to realize signal transmission.
In addition, in order to reduce interference of the main board 13 and the upper elements to the antenna, absorption of the metal material to the antenna efficiency is reduced. In this embodiment, in the connection device between the FPC antenna and the motherboard, the height of the antenna thimble is greater than 2.5mm.
By increasing the distance between the FPC antenna and the main board 13 through the height of the antenna thimble, the interference of PCBA and the elements on the PCBA on the PCB antenna can be relatively reduced, and the absorption of the metal material to the antenna efficiency is reduced.
