Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a printed circuit board includes a circuit substrate 10 and an antenna 20, a first stamp hole (not shown) is formed in a side surface of the circuit substrate 10 in a direction intersecting a thickness direction of the circuit substrate 10, and the antenna 20 is disposed in the first stamp hole along a routing direction of the first stamp hole.
Specifically, the routing direction of the first stamp hole is the direction of opening the first stamp hole, i.e., the direction intersecting the thickness direction of the circuit substrate 10. The edges of the printed circuit board are cut to form a series of half-holes, i.e. stamp holes, by electroplating graphitization of the holes or through-holes at the edges of the printed circuit board, i.e. in the actual printed circuit board, the stamp holes are usually in the form of half-holes. The traditional stamp hole design is that stamp holes are generally formed in the thickness direction of a printed circuit board, and a plurality of stamp holes in a half-hole form are usually formed in the surface of the same side of each printed circuit board, specifically, as shown in fig. 2, the length of each stamp hole (i.e., the length of a trace corresponding to the stamp hole) depends on the thickness of the printed circuit board, the thickness of the printed circuit board is what, and the length of each stamp hole formed in the direction can only reach the same size.
The antenna 20 in the printed circuit board generally needs a larger area to achieve the radiation effect of the antenna 20, while the thickness of the circuit board of the printed circuit board is generally smaller, only about 0.8mm-1.5mm, and obviously, the stamp hole formed along the thickness direction of the circuit board 10 cannot meet the design requirement of the antenna 20 in length and area. The stamp hole can only be used for SMT (Surface Mounted Technology) welding, and the stamp hole in the traditional printed circuit board cannot be well utilized. The technical scheme of this application will originally set up the stamp hole on the thickness direction of circuit substrate 10 again, change into and set up first stamp hole with the crossing direction of thickness direction, printed circuit board's length and width (being the length and the width of circuit substrate 10 upper and lower surface) are generally very big, often reach dozens of millimeters or even hundreds of millimeters, through beginning first stamp hole in the crossing direction with the thickness direction, the length of the corresponding line of first stamp hole is greater than 1.5mm far away this moment, generally can expand to about 40mm, accord with general antenna 20 design requirement completely. In the antenna 20 of the present application, the thickness (i.e., the side surface) of the printed circuit board and the exposed postage stamp hole of the printed circuit board act as the antenna 20 to radiate the signal, and the antenna 20 has very strong directivity and can be better used for directional transmission or short-distance transmission.
In one embodiment, the number of the side surfaces of the circuit substrate 10 on which the first stamp hole is opened is two or more.
Specifically, the circuit substrate 10 generally includes four side surfaces, each of which may be used to perform the arrangement of the antenna 20. Therefore, in order to further increase the length of the antenna 20, increase the radiation area of the antenna 20, design the antenna 20 in a specific radiation direction, and the like, the first stamp hole may be simultaneously opened in two or more side surfaces and the antenna 20 may be designed in the corresponding first stamp hole, that is, the antenna 20 may be designed by simultaneously opening the first stamp hole in two side surfaces, three side surfaces, or four side surfaces.
It will be appreciated that when the number of side surfaces on which the first stamp hole is formed is two, the two side surfaces may be adjacent side surfaces or opposite side surfaces, as long as the antennas 20 provided on the two side surfaces can be combined together by other components of the printed circuit board to form the same antenna 20 for both signal receiving and transmitting operations. It should be noted that, in one embodiment, the first stamp hole may be formed in only one of the side surfaces of the circuit substrate 10, and the antenna 20 may be designed, as long as the resulting antenna 20 is ensured to effectively perform the signal receiving and transmitting operations.
Referring to fig. 3, in an embodiment, the printed circuit board further includes a matching circuit 30, the matching circuit 30 is disposed on the circuit substrate 10, and the antennas 20 disposed on any two adjacent side surfaces are connected through the matching circuit 30.
Specifically, in order to ensure that the antennas 20 disposed on the respective side surfaces can be effectively combined to realize the final signal transmitting and receiving functions, the matching circuits 30 are disposed between the respective adjacent side surfaces and connected to each other, and the antennas 20 disposed on the different side surfaces are connected to form one antenna 20. It is understood that in other embodiments, the matching circuit 30 may be used to connect the antennas 20 on the opposite surfaces, as long as it is ensured that the antennas 20 are finally connected to form one antenna 20 through the matching circuit 30. The present embodiment uses the matching circuit 30 to connect the antennas 20 on the adjacent side surfaces, and has the advantages of simple layout and saving the area of the circuit substrate 10 while ensuring that the finally formed antenna 20 has good signal transmitting and receiving functions.
It should be noted that when the number of side surfaces of the circuit substrate 10 in which the first stamp hole is opened is not uniform, the number of the corresponding matching circuits 30 is also not uniform. When the antennas 20 are disposed only on the adjacent side surfaces, in order to realize the combination between the antennas 20, only one matching circuit 30 needs to be disposed at a position corresponding to the circuit substrate 10 near both side surfaces. Similarly, when the number of side surfaces where the first stamp hole is provided for designing the antenna 20 is three, two matching circuits 30 are required to realize the combination between the antennas 20; when the number of side surfaces where the first stamp hole is provided for the design of the antenna 20 is four, three matching circuits 30 are required to realize the combination between the antennas 20.
In one embodiment, the matching circuit 30 includes an inductor, a first capacitor and a second capacitor, one end of the inductor is connected to one end of the first capacitor and the antenna 20 in the first side surface, the other end of the inductor is connected to one end of the second capacitor and the antenna 20 in the second side surface, the other end of the first capacitor and the other end of the second capacitor are both grounded, and the first side surface and the second side surface are adjacent side surfaces.
Specifically, a simple matching circuit 30 is formed by an inductor and two capacitors, so that the antennas 20 disposed on any two adjacent side surfaces are connected together to realize transmission and reception of signals. The matching circuit 30 of this type is used to realize the splicing and assembling operations of different sections of antennas 20, and has the advantage of saving the occupied area of the circuit substrate 10.
It is understood that in other embodiments, other types of matching circuits 30 may be used to perform the antenna 20 combining operation in the adjacent side surfaces in combination with the actual usage scenario of the printed circuit board, as long as the resulting one antenna 20 can achieve effective signal receiving and transmitting operations.
Referring to fig. 3, in one embodiment, a second stamp hole is further formed in the side surface of the circuit substrate 10 along the thickness direction, the first stamp hole is communicated with the second stamp hole, and the antenna 20 is disposed along the routing direction of the first stamp hole and the routing direction of the second stamp hole.
Specifically, in the present embodiment, the same side surface of the circuit substrate 10 includes both the second stamp hole disposed along the thickness direction of the circuit substrate 10 and the first stamp hole designed in the direction intersecting the thickness direction, and the first stamp hole and the second stamp hole are communicated with each other. When designing the antenna 20 on the side surface, the antenna 20 can be laid out along the thickness direction of the circuit board 10 and the direction intersecting the thickness direction, and in this case, the antenna 20 is designed in a meandering manner, which is not a simple one-line design. Through the technical scheme of the embodiment, the antenna 20 can be designed in the thickness direction of the circuit substrate 10 and the direction intersecting with the thickness direction, so that the length of the antenna 20 can be further increased, the antenna 20 can be designed in a more flexible radiation direction, and the radiation efficiency of the antenna 20 of the printed circuit board is further enhanced.
With continued reference to FIG. 3, in one embodiment, the routing direction of the first stamp hole is perpendicular to the routing direction of the second stamp hole.
Specifically, the trace direction of the first stamp hole is perpendicular to the trace direction of the second stamp hole, that is, the antenna 20 in the first stamp hole is laid out in the direction perpendicular to the thickness direction, and the finally obtained antenna 20 has a regular zigzag shape on the side surface. The scheme is adopted to open the first stamp hole, and the stamp hole opening method has the advantages of simple process and easiness in implementation. It is understood that in other embodiments, the trace direction of the first stamp hole and the trace direction of the second stamp hole may be at an angle greater than 0 degree and less than 90 degrees, as long as the total length of the antenna 20 designed in the first stamp hole and the second stamp hole reaches the design requirement of the antenna 20.
Furthermore, in an embodiment, as shown in fig. 4, a plurality of first stamp holes and a plurality of second stamp holes may be formed on the same side surface of the circuit substrate 10, the routing direction of each first stamp hole is the same and is perpendicular to the routing direction of each second stamp hole, and the first stamp holes and the second stamp holes are sequentially connected, so as to finally obtain the bent antenna 20 structure, which can also implement the operations of receiving and sending signals.
In one embodiment, the number of the second stamp holes is two, and the second stamp holes are respectively disposed at two ends of the first stamp hole in the routing direction.
Specifically, when two second stamp holes are respectively disposed at both ends of the first stamp hole, the corresponding antennas 20 are arranged in a zigzag shape as shown in fig. 3, so that the resulting antenna 20 is long to meet the requirement of the length design of the antenna 20. Meanwhile, due to the design of the second stamp hole at two ends of the first stamp hole and the antenna 20, when the antenna 20 is designed on a plurality of side surfaces at the same time, the antenna 20 is closer to the matching circuit 30 arranged on the circuit substrate 10, and the matching circuit 30 can more conveniently combine the antennas 20 on the side surfaces into one antenna 20.
In one embodiment, the trace shape of the first stamp aperture includes at least one of a straight line or an arc. It will be appreciated that the direction intersecting the thickness direction of the circuit substrate 10 may be a regular straight direction, or may be an arc direction having a certain radian, that is, the first stamp hole may be shaped as a straight line, an arc line, or a combination of a straight line and an arc line, and the antenna 20 designed correspondingly may be at least one of a straight line and an arc line, so as to obtain an antenna 20 with a sufficient length to implement the reception and transmission of signals. In this embodiment, the vertical (i.e., along the thickness direction) stamp hole is changed to be combined with the vertical and horizontal (i.e., perpendicular to the thickness direction) or arc-shaped stamp hole, and the antenna 20 is further designed in each stamp hole, so that the radiation area of the antenna 20 can be effectively increased, the design of the antenna 20 is enriched, and the routing of the antenna 20 is more flexible.
In the printed circuit, a first stamp hole is formed in a side surface of the circuit board 10 in a direction intersecting the thickness direction, and the antenna 20 of the printed circuit board is disposed along a routing direction of the first stamp hole (i.e., a direction intersecting the thickness direction of the circuit board 10). By reasonably applying the side surface of the circuit substrate 10 in the above scheme, the antenna 20 originally printed on the front surface of the circuit substrate 10 and occupying a certain area is arranged on the side surface, so that the radiation area of the antenna 20 can be effectively increased; and each side surface of the printed circuit board can be utilized, so that the radiation direction of the antenna 20 can be flexibly set, and the antenna 20 is ensured to have stronger radiation efficiency.

The edges of the printed circuit board are cut to form a series of half-holes, i.e. stamp holes, by electroplating graphitization of the holes or through-holes at the edges of the printed circuit board, i.e. in the actual printed circuit board, the stamp holes are usually in the form of half-holes. The traditional stamp hole design is that stamp holes are generally formed in the thickness direction of a printed circuit board, and a plurality of stamp holes in a half-hole form are usually formed in the surface of the same side of each printed circuit board, specifically, as shown in fig. 2, the length of each stamp hole (i.e., the length of a trace corresponding to the stamp hole) depends on the thickness of the printed circuit board, the thickness of the printed circuit board is what, and the length of each stamp hole formed in the direction can only reach the same size.
The antenna 20 in the printed circuit board generally needs a larger area to achieve the radiation effect of the antenna 20, while the thickness of the circuit board of the printed circuit board is generally smaller, only about 0.8mm-1.5mm, and obviously, the stamp hole formed along the thickness direction of the circuit board 10 cannot meet the design requirement of the antenna 20 in length and area. The stamp hole can only be used for SMT welding, and the stamp hole in the traditional printed circuit board cannot be well utilized. The technical scheme of this application will originally set up the stamp hole on the thickness direction of circuit substrate 10 again, change into and set up first stamp hole with the crossing direction of thickness direction, printed circuit board's length and width (being the length and the width of circuit substrate 10 upper and lower surface) is generally very big, often reaches dozens of millimeters or even hundreds of millimeters, through beginning first stamp hole in the crossing direction with the thickness direction, the length of the corresponding line of first stamp hole this moment is greater than 1.5mm far away, accord with general antenna 20 design requirement completely.
It is to be understood that the type of electronic device is not exclusive and in one embodiment the electronic device is a cell phone or a tablet computer. In other embodiments, the electronic device may also be other types of electronic devices, and the printed circuit board in the above embodiments may be used as long as the internal circuit board of the electronic device needs to be provided with the PCB antenna 20.
