Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The antenna structure according to the embodiment of the present invention, as shown in fig. 1 and 2, includes: a base layer 10 and an antenna layer 20; the antenna layer 20 is attached to the base layer 10; wherein, the antenna layer 20 is made of graphite material.
The antenna structure applying the technical scheme of the invention comprises the following components: a base layer 10 and an antenna layer 20; the antenna layer 20 is attached to the base layer 10; wherein, the antenna layer 20 is made of graphite material. Therefore, on the basis of ensuring the working performance of the conducting circuit of the antenna, the complexity of the process is reduced, the production cost is reduced, the antenna is more environment-friendly, and the problem that the process of the antenna of the intelligent terminal device in the prior art is complex is solved.
The polarization mode of the antenna refers to the direction of the electric field intensity formed when the antenna radiates, and can be divided into the following according to the polarization mode of the electric field radiated by the antenna: linear polarization, circular polarization, elliptical polarization. Linear polarization is further divided into: horizontal polarization, vertical polarization. When the electric field intensity direction is vertical to the ground, the electric wave is called a vertical polarized wave; when the electric field strength is directed parallel to the ground, the electric wave is called a horizontally polarized wave.
The antenna design takes into account the frequency band and the operating environment. The working frequency band of the mobile phone is divided into high, medium and low frequency bands 3, the low frequency is about 900Mhz, and the high frequency is about 2.5 Ghz. A plurality of interference devices are arranged on the mainboard of the mobile phone. Therefore, a linearly polarized PIFA antenna form is mainly used. When the antenna is designed, corresponding straight lines of different frequency bands are led out from a unified feed point, and the antennas of the different frequency bands are separated. The length of the antenna wire corresponding to the frequency band is 1/4 of the wavelength, the wiring width is recommended to be 1mm, the actual shape of the wiring is a plurality of continuous curves led out from a uniform feed point because the wiring needs to avoid influencing devices on a pcb, and the low-frequency line surrounds the high-frequency line. The length of the low-frequency wire is about 7-8cm, the length of the high-frequency wire is about 3cm, and the specific size and shape are adjusted according to the specific conditions of a real machine. The resistance value of the antenna affects the radiation efficiency, and the loss caused by low resistance value is less.
In specific implementation, the antenna feed point of the circuit board of the smart mobile terminal device is usually connected to the antenna structure by a metal dome or pogo pin. Therefore, in order to ensure reliable contact, as shown in fig. 1 to 4, a feed contact 30 is disposed at a corresponding contact point of the antenna structure, the feed contact 30 is disposed at a feed point of the antenna layer 20, that is, a feed gold finger is attached at the feed point, and the recommended size of the feed contact 30 is: 1.5mmx2.5mm, and a thickness of 0.15 mm.
Further, the thickness of the antenna layer 20 is 0.1-0.15mm, that is, the thickness of the graphite layer is 0.1-0.15mm, the antenna layer 20 is a continuous conductive path, and the shape of the antenna layer 20 is made according to the frequency band requirement of a specific device, so as to resonate out a signal.
When designing the shape of the antenna layer 20, a single curved surface or a plane is cut out of the antenna area of the mobile phone shell, the structural diagram of the external shape of the antenna layer 20 is designed according to the conventional design mode of fpc, and the structural diagram is developed into a plan view through software. The antenna assembly may follow the fpc antenna assembly.
In order to effectively protect the antenna layer 20, the antenna structure further includes: and a protective layer 40, wherein the protective layer 40 is attached to the antenna layer 20. In the thickness direction, the base layer 10 and the protective layer 40 wrap the antenna layer 20 in the middle, and the protective layer 40 is cut to avoid at the feed contact 30 of the feed point. Specifically, the base layer 10 and the protective layer 40 are both high temperature resistant polyester films (PET films), and are each 0.05mm thick. In order to ensure a structure capable of being fixed with the antenna layer 20, a back adhesive with a thickness of 0.05mm is attached to the base layer 10.
The graphite material has good heat conductivity, so that the antenna layer 20 can transfer heat from the antenna feed point of the main board to the rear case of the mobile phone for heat dissipation.
In order to further improve the heat dissipation performance of the antenna layer 20, as shown in fig. 4, the antenna structure further includes: a heat dissipation layer 50; the heat dissipation layer 50 is provided with a hollow structure matched with the shape of the antenna layer 20, the antenna layer 20 is arranged in the hollow structure of the heat dissipation layer 50, and the heat dissipation layer 50 is made of graphite materials.
Because the heat conductivity of graphite is good, graphite antenna can also give off the backshell of cell-phone with the antenna feed point transmission of heat from the mainboard. In order to increase the heat dissipation effect, a separate heat dissipation layer 50 is formed by adding a continuous graphite layer around the trace of antenna layer 20, and the graphite layer of heat dissipation layer 50 is not electrically connected to the trace of antenna layer 20, is insulated from the trace of antenna layer 20, and does not overlap in the thickness direction. The heat dissipation function can be enhanced on the same thickness space. This solution can replace a separate heat sink. That is, 2 graphite layers are juxtaposed, one being the antenna layer 20 and the other being the heat dissipation layer 50.
In addition, a certain amount of graphite powder can be mixed into the material of the mobile phone shell to increase the heat dissipation performance, but the ratio must be controlled within a certain range. If the graphite powder is added too much, the shell is conductive, and the radio frequency performance of the antenna is affected.
According to a second embodiment of the present invention, there is provided an intelligent terminal device, including an antenna structure, where the antenna structure is the antenna structure of the foregoing embodiment. By applying the intelligent terminal device with the antenna structure of the embodiment, the complexity of the process procedure is reduced, the production cost is reduced, the intelligent terminal device is more environment-friendly on the basis of ensuring the working performance of the conducting circuit of the antenna, and the problem that the process procedure of the antenna of the intelligent terminal device in the prior art is complex is solved.
According to a third embodiment of the present invention, there is provided a method for manufacturing an antenna structure, where the antenna structure is the antenna structure of the above embodiment, and the method specifically includes the following steps:
s102: preparing a graphite material;
s104: coating or spraying an adhesive layer matched with the preset shape on the base layer 10 of the antenna structure according to the preset shape of the antenna layer 20 of the antenna structure;
s106: and uniformly covering the prepared graphite material on the adhesive layer, and carrying out hot pressing and drying.
Specifically, in step S102, the natural graphite is first crushed and ground, and then crushed several times, and finally ground into uniform fine particles with a diameter of about 10 to 50 μm by using a classified ultra-fine grinder. The fineness of the graphite is realized by adjusting the rotating speed and the air quantity of the grinding machine. The particles must be filtered, screened and decontaminated. The selected screen mesh is 325 mesh to 1800 mesh.
Adding a certain proportion of hot-melt conductive adhesive particles into the ground graphite powder and mixing, wherein the hot-melt conductive adhesive particles are ground to reach the size of 50-150um, and the particles are filtered, screened and purified. The screen mesh is 170 meshes to 325 meshes. Drying and static electricity removal are required due to environmental factors. The environmental temperature is kept between 20 and 25 ℃, and the humidity is controlled within the range of 20 to 50 percent.
In step S104, a hot melt adhesive with a cut antenna shape is attached to the base layer 10, or a conductive glue (both conductive and non-conductive, and the conductive glue has better performance) is printed or sprayed on the base layer 10 according to a preset shape of the antenna layer 20. The graphite powder can also use a special solvent as a carrier, can realize jet printing, and can complete the track of the antenna on a plane or a curved surface, and the same operation can be adopted if graphene is used as the antenna.
In step S106, as shown in fig. 5 and 6, the mixed graphite powder is uniformly laid on the track of the antenna layer 20, specifically, the graphite powder is uniformly covered on the corresponding antenna track by the automatic track feeding mechanism, the flow rate of the powder at the funnel outlet of the automatic track feeding mechanism is controlled by the sensor, and the feeding track is controlled by the computer program.
The graphite powder is heated and rolled by the hot-pressing roller shaft 60, the hot-pressing roller shaft 60 adopts an electrically heated constant-temperature hot-pressing roller shaft, the temperature is kept at 130-180 ℃, and the temperature is generally kept at 135 ℃. The hot pressing pressure is 10-20 psi, and the time between hot pressing is 2-5 seconds. The conductivity can be improved by hot pressing for many times, and the hot pressing is generally carried out for 2 times.
After the hot pressing is completed, the edge of the cabinet of the antenna layer 20 has an excess graphite layer, and in order to ensure the performance of the antenna, the excess graphite layer needs to be trimmed and removed. Specifically, the portion exceeding the width of the antenna track is removed by cutting with a knife die or laser. The track width of the antenna layer 20 is controlled to be 0.7mm-1 mm.
Finally, the surface of the completed antenna layer 20 is covered with a protective layer 40. At the antenna feed point, to ensure the reliability of the contact, a thin gold finger, i.e., a feed contact 30, is attached above the antenna layer 20. The size of the golden finger is controlled to be 1.5x2.5mm, the distance is 0.5mm, and the material thickness of the protective film is 0.05 mm.
If graphene is used for the antenna layer 20, the electronic surface wave generated on the surface of the graphene is the widest due to the honeycomb structure of the graphene. The research shows that: the working frequency of the graphene-based nano antenna is between 0.1 and 10 terahertz, and the data rate in a wireless network can be improved by more than two orders of magnitude. At present, the frequency band of the graphene antenna is mainly used for near field communication, such as RFID (radio frequency identification devices).
According to a fourth aspect of the present invention, there is provided a method for manufacturing an antenna structure, where the antenna structure is the antenna structure of the foregoing embodiment, the method specifically includes the following steps:
s202: preparing a graphite material;
s204: coating or spraying an adhesive layer on the base layer 10 of the antenna structure, and uniformly covering the prepared graphite material on the adhesive layer for hot pressing and drying;
s206: and cutting the antenna layer 20 with the same shape as the preset shape on the graphite layer after the hot pressing according to the preset shape of the antenna layer 20 of the antenna structure.
The process of preparing the graphite material in step S202 is the same as that of the third embodiment, and is not described again here.
In step S204, when the hot melt adhesive is coated on the base layer 10 or the conductive glue is printed or sprayed, the spraying is not required to be performed according to the preset shape of the antenna layer 20. Specifically, the whole hot melt adhesive may be coated on the base layer 10, or the whole surface of the base layer 10 may be printed or sprayed with the conductive glue, and then the mixed powder of the graphite powder and the hot melt conductive adhesive particles is uniformly laid, and then the graphite conductive sheet layer material is formed by performing constant temperature hot pressing through the hot press roller shaft 60.
In step S206, according to the preset shape of the antenna layer 20, a desired shape of the antenna layer 20 is directly cut on the complete graphite conductive sheet material by using cutting die cutting or laser cutting. Finally, the protective layer 40 and the feed contact 30 are attached to complete the manufacture of the graphite antenna.
