Description

Structure integrated with antenna and electronic equipment

Technical Field

The disclosure relates to the technical field of terminals, and in particular relates to a structural member integrated with an antenna and electronic equipment.

Background

Electronic devices currently tend to be designed with narrow borders on the screen, which can enhance the visual experience. But at the same time the structural space of the screen area becomes limited, making it difficult to accommodate conventional antenna systems.

To solve such a problem, an antenna may be disposed at a system end of the electronic device. However, when the antenna is arranged at the system end, the antenna is close to the electromagnetic noise source, and noise reduction cost of the system end can be increased.

Detailed Description

In order to make the objects, features and advantages of the present disclosure more comprehensible, the technical solutions in the embodiments of the present disclosure will be clearly described in conjunction with the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

Fig. 1 shows a schematic diagram of a composition structure of a structural member integrated with an antenna according to an embodiment of the disclosure, as shown in fig. 1, where the structural member includes a coupling feed branch 1, an electronic device housing 2, and a wireless radiation branch 3, where the coupling feed branch 1 is disposed on an inner surface of the electronic device housing 2 and is used for transmitting an electric signal transmitted by a radio frequency cable 4 to the wireless radiation branch 3 in a coupling manner, and the wireless radiation branch 3 is disposed on an outer surface of the electronic device housing 2 and is used for converting the electric signal transmitted by the coupling feed branch 1 into an electromagnetic wave for radiation.

The electronic device housing 2 is a supporting structure for coupling the feed branch 1 and the wireless radiation branch 3, and may be a top cover of a notebook computer, a rear cover of a tablet computer, and the like. The coupling feed branch 1 is arranged on the inner surface of the electronic device housing 2 for transmitting an electrical signal from the radio frequency cable 4 to the wireless radiating branch 3 by means of coupling. The coupling mode may be implemented by using a variation of an electromagnetic field, and is not limited herein. The coupling feed stub 1 may be specifically manufactured by a material such as a PCB (Printed Circuit Board, a printed circuit board), an FPC (Flexible Printed Circuit, a flexible printed circuit board), an FFC (Flat Flexible Cable, a flat flexible cable), or a metal material. The wireless radiation branch 3 is a metal sheet or strip having a specific shape, which can be set according to the specific situation, and is not particularly limited in the present disclosure. The wireless radiation branch 3 is formed on the outer surface of the electronic device case 2 by printing or spraying or the like for converting an electric signal received from the coupling feed branch 1 into an electromagnetic wave and radiating into the surrounding space. So that other wireless devices can receive these electromagnetic waves to enable wireless communication between the devices.

The wireless device of the electronic device is usually arranged around the screen, which can cause difficulty in realizing the design requirement of the narrow frame of the screen if the wireless device occupies a large space. According to the antenna structure, the antenna function is realized by adopting the coupling feed mode on the inner surface and the outer surface of the electronic equipment shell, so that the inner space of the electronic equipment is greatly optimized, and the design requirement of a narrow frame of the electronic equipment can be met. Compared with the printed antenna in the prior art, the printed antenna adopts the mode of different-surface coupling feed, does not need to carry out perforation, welding spot and other operations on the shell of the electronic equipment, and ensures that the shell of the electronic equipment is more attractive. Compared with the method for arranging the antenna at the system end in the prior art, the antenna is arranged at the screen side of the electronic equipment by the structure disclosed by the invention, SAR (Specific Absorption Rate, electromagnetic wave absorptivity) test is not required to be carried out on the electronic equipment, and the SAR authentication cost can be saved.

In one embodiment of the present disclosure, the electronic device housing 2 is non-metallic.

Since the metal has conductivity, it can act as a shield for electromagnetic waves, limiting the ability of the wireless radiating branch 3 to radiate electromagnetic waves outwards and possibly interfering with the signal received by the coupling feed branch 1. Accordingly, the electronic device case 2 in the present disclosure is made of a non-metal material. In one embodiment, plastic, basalt, etc. materials may be used.

In one embodiment of the present disclosure, as shown in fig. 2, the coupling feed branch 1 includes a first feed branch 11 and a second feed branch 12. There is no direct electrical connection between the first and second feed branches 11, 12, which interact by way of coupling. The design mode greatly reduces the size of the coupling feed branch 1, thereby solving the problem that the internal space is limited because the electronic equipment is designed for realizing a narrow frame.

In one embodiment of the present disclosure, as shown in fig. 2, the radio frequency cable 4 includes an inner conductor 42 and an outer conductor 41, where the inner conductor 42 and the outer conductor 41 are concentrically disposed, the inner conductor 42 of the radio frequency cable 4 is connected to the second feeding branch 12 for transmitting an electrical signal transmitted by the radio frequency cable 4 to the wireless radiating branch 3, and the outer conductor 41 of the radio frequency cable 4 is connected to the first feeding branch 11 for reflowing the electrical signal.

The radio frequency cable 4 is a coaxial cable for transmitting radio frequency signals and comprises at least an inner conductor 42 and an outer conductor 41, the inner conductor 42 and the outer conductor 41 being arranged generally concentrically, i.e. the inner conductor 42 is located in the centre of the cable and the outer conductor 41 surrounds the inner conductor 42 as a shielding. The inner conductor 42 is connected to the second feed branch 12 for transmitting the radio frequency signal generated by the signal source to the second feed branch 12 and for receiving the radio frequency signal radiated by the antenna. The outer conductor 41 serves to prevent influence of external electromagnetic interference on signals and to provide a return path for current, ensuring current balance of the antenna system.

In one embodiment of the present disclosure, the structure further comprises a paint layer covering the wireless radiating branch.

After the wireless radiation branch 3 is arranged on the outer surface of the electronic equipment shell 2, paint is sprayed on the outer surface, so that a paint layer is formed on the surface. The paint layer can make the surface of the electronic equipment more beautiful, and can protect the wireless feed branch 3.

In one embodiment of the present disclosure, the thickness value of the electronic device case 2 is 0.8 mm or more and 1.8 mm or less. The thickness of the electronic device housing 2 affects the performance of the antenna, and the smaller the thickness, the better the performance of the antenna, and in order to make the performance of the antenna at a higher level, the electronic device housing 2 having a thickness of 0.8 mm to 1.8 mm may be preferable.

In one embodiment of the present disclosure, the length of the coupling feed stub 1 is 40 mm and the width is 2 mm. The specific materials, shapes, numbers and the like of the coupling feed branches 1 are not particularly limited, and can be selected according to practical application requirements. To meet the design requirement of the narrow frame of the electronic device, the coupling feed branch 1 with the length of 40 mm and the width of 2 mm is preferably used in the present disclosure.

In one embodiment of the present disclosure, as shown in fig. 3, the wireless radiating branch 3 has a length of 40 mm and a width of 12 mm. Similarly, the specific materials, shapes, numbers, etc. of the wireless radiation branches 3 are not specifically limited, and may be selected according to practical application requirements. In order to meet the design requirements of achieving high transmission efficiency and achieving a narrow frame of the electronic device simultaneously with the feeding coupling branch 1, a wireless feeding branch 3 with a length of 40 mm and a width of 12 mm is preferably used in the present disclosure.

In another aspect of the present disclosure, an electronic device is disclosed that includes the structure integrated with the antenna function in the above embodiment. The electronic device may be a notebook computer, a tablet computer, a smart phone, etc. Taking an electronic device as a notebook computer as an example, at this time, the electronic device housing is a top cover of the notebook computer, fig. 4 shows a schematic view of an inner surface of the electronic device housing according to an embodiment of the disclosure, and as shown in fig. 4, the inner surface of the top cover of the notebook computer is provided with a coupling feeding branch 1, where the coupling feeding branch 1 is connected with a radio frequency cable 4. Fig. 5 is a schematic view of an outer surface of an electronic device housing according to an embodiment of the disclosure, and fig. 5 is an outer surface of a top cover of a notebook computer, and is provided with a wireless radiation branch 3.

Fig. 6 is a schematic process flow diagram of manufacturing a structural member according to an embodiment of the disclosure, and as shown in fig. 6, taking an electronic device as an example of a notebook computer, a plastic structural member of a top cover of the notebook computer is obtained first. And (3) manufacturing the wireless radiation branches 3 on the outer surface of the plastic structural member by adopting a printing or spraying technology to obtain a semi-finished product with the wireless radiation branches 3 on the outer surface. And (5) spraying paint on the outer surface to form a paint layer, and obtaining the finished plastic structural member. And assembling the finished plastic structural member, the feed coupling branch 1 and the radio frequency cable 4 to obtain the structural member integrated with the antenna.

According to experimental comparison, on one hand, compared with a traditional antenna system, the different-surface coupling antenna system disclosed by the invention can save certain manufacturing cost and has better antenna performance. And the size is smaller, so that the internal space of the electronic equipment can be saved, and the design requirement of the narrow frame of the electronic equipment is met. On the other hand, the different-surface coupling antenna system can be arranged on the screen side, SAR authentication of the electronic equipment is not needed, and SAR authentication cost is saved. And because the antenna is arranged at the system end and an additional noise reduction measure is needed to be adopted at the system end, the cost of noise reduction at the system end is saved.
