The laptop antenna with integrated heat dissipation vent of the embodiment of the present invention can be used in the laptop mode and closed mode of the laptop's usage state. The laptop mode is the mode in which the user normally opens the laptop and uses the keyboard with both hands, such as Figure 1 The closed mode is the mode in which the upper cover (first metal shell 1) and the lower cover (second metal shell 2) of the laptop are closed to each other. Figure 2 The laptop mode usually allows users to use the laptop normally, so wireless communication is usually required to be turned on. The closed mode can be set to standby mode according to user needs, or just turn off the screen while the laptop remains powered on normally, so the user must also be able to set or choose whether to turn on wireless communication.

[0034] Figure 1 and Figure 2 The X-axis is parallel to the edge of the case and parallel to the rotation axis; the positive Y-axis (+Y) is equivalent to the direction from the heat dissipation port to the outside (from the heat dissipation port away from the body), that is, the direction of the heat dissipation airflow output; in addition, the Z-axis is defined according to the XY axis using the right-hand rule, and the positive Z-axis direction is exactly above the space when the laptop is placed horizontally. The XYZ axes of subsequent drawings are defined in the same way. Figures 3 to 8 The diagrams are respectively the front, top, left, right, bottom and back of the laptop antenna with integrated heat dissipation vent provided by the embodiment of the present invention. Each diagram has XYZ axes as coordinate axes, which can be compared to the flipping direction of the antenna in the diagram. Figure 3 The front of the antenna is facing the outside of the casing, that is, Figure 3 The multiple opening structures shown are Figure 1 and Figure 2 The appearance diagram of the laptop can be seen. Figure 3 There are many open pore structures, and Figure 1 and Figure 2 It is only used to simply indicate the state of having multiple openings and is not Figure 1 and Figure 2 is exactly the same as Figure 3 The number and size ratio of the openings. Figure 4 The front of the antenna is shown in Figure 1. The antenna part is fed by the top surface as a feed line, connected to the feed point and the ground terminal configuration. The top surface of the antenna is directly attached and locked into the laptop case, that is, locked into the second metal shell 2 (bottom cover). And Figure 3 This refers to the angle of view from the top of the laptop when the antenna is installed on the laptop and the laptop is disassembled. Usually, the corresponding alignment parts or locking parts have non-metallic parts to avoid conduction with the feed line and excitation pattern (circuit), which would affect the antenna performance. Figure 5 and Figure 6 , which are the side views from the left and right. Figure 7 The back of the antenna is facing the inside of the casing, and the radiator flow flows from the inside of the casing to the outside of the casing, that is, the heat dissipation airflow flows from the back of the antenna to the front of the antenna. Figure 8 It can be regarded as the viewing angle of the bottom surface of the antenna.

[0035] In other words, corresponding to the XYZ three axes, the top surface of the antenna is facing the positive Z axis, the bottom surface of the antenna is facing the negative Z axis, the left side of the antenna is facing the positive X axis, the right side of the antenna is facing the negative X axis, the front side of the antenna is facing the positive Y axis, and the back side of the antenna is facing the negative Y axis. Figure 3 It is a front view of a laptop antenna integrated with a heat dissipation port provided by an embodiment of the present invention. Figure 3 The front side shown is the exposed surface of the heat dissipation frame 5 when it is installed in the housing. Figure 4The two antenna excitation patterns and the corresponding feeder positions in the heat dissipation frame 5 are shown, which will be described later. The heat dissipation frame 5 is used to be installed in a laptop. The antenna placed in the heat dissipation port of the embodiment of the present invention is particularly suitable for laptops with a metal casing. The antenna as a transceiver of electromagnetic wave signals is integrated into the heat sink (heat dissipation frame 5). Therefore, the antenna design does not need to use other blocks of the casing, and the casing does not need to be specially designed with a non-metallic antenna window (for electromagnetic wave transmission and reception).

[0036] Refer to Figures 3 to 11 , Figure 4 It is a top view schematic diagram of a laptop antenna integrated with a heat dissipation port provided by an embodiment of the present invention. Figure 5 It is a schematic diagram of the left side of the laptop antenna integrated with the heat dissipation port, that is, it corresponds to the schematic diagram of the left side of the heat dissipation frame 5. Figure 6 It is a schematic diagram of the right side of the antenna arranged in the heat dissipation port, that is, it corresponds to the schematic diagram of the right side of the heat dissipation frame 5. Figure 7 It is a schematic diagram of the back side of a laptop antenna integrated with a heat dissipation port provided by an embodiment of the present invention. Figure 8 It is a bottom schematic diagram of a laptop antenna integrated with a heat dissipation port provided by an embodiment of the present invention. Figures 3 to 8 The oblique line block shows the shape and area of ​​the laser engraved metal block, which includes not only the main antenna excitation pattern 6 and the auxiliary antenna excitation pattern 7, but also the grounding block. The blocks not specially marked in the figure are all grounded. Fig. 9 It is a three-dimensional schematic diagram of the top surface of the laptop antenna with integrated heat dissipation vent provided by an embodiment of the present invention from an oblique perspective. In order to conveniently display the shape of the heat dissipation vent, the antenna module is turned upside down only to more clearly identify the heat dissipation vent and the antenna excitation pattern. Fig.10 FIG. 1 is a perspective view of the bottom surface of a laptop antenna with integrated heat dissipation port provided by an embodiment of the present invention. Figure 1 , Figure 2 , and in conjunction with the above Figures 3 to 10 , it should be possible to understand the general shape of the laptop antenna with integrated heat dissipation port provided in the embodiment of the present invention. The laptop antenna with integrated heat dissipation port in the embodiment of the present invention comprises a first metal shell 1, a second metal shell 2 and a heat dissipation frame 5. The second metal shell 2 is connected to the first side 11 of the first metal shell 1 by using the first metal shaft 3 and the second metal shaft 4 to form a metal closed slot MCS, referring to Figure 1 and Figure 2. The metal closed slot MCS is a narrow slot in the shape of a straight line. The length of the slot is approximately the spacing between the first metal shaft 3 and the second metal shaft 4, and the width of the slot is approximately the gap between the first metal shell 1 and the second metal shell 2. The heat dissipation frame 5 is a non-conductor, which is arranged in the second metal shell 2 and is located within the metal closed slot MCS. The actual arrangement of the heat dissipation frame 5 is, for example, that the second metal shell 2 has an installation position for installing the heat dissipation frame 5, and this installation position is adjacent to the edge of the metal closed slot MCS, and based on the integrity of the assembly and function, the heat dissipation frame 5 will be covered with a non-conductor component. This non-conductor component and the second metal shell 2 are fully assembled in appearance, and most of the heat dissipation frame 5 is hidden in the casing, and only a plurality of heat dissipation openings are exposed on the side of the casing. The heat dissipation frame 5 is provided with a main antenna excitation pattern 6 and an auxiliary antenna excitation pattern 7, wherein the main antenna excitation pattern 6 and the auxiliary antenna excitation pattern 7 are both laser engraved on the heat dissipation frame 5.

[0037] In terms of antenna characteristics, the main antenna excitation pattern 6 and the auxiliary antenna excitation pattern 7 are the exciters of the metal closed slot MCS. The main antenna excitation pattern 6 and the auxiliary antenna excitation pattern 7 are both used to excite multiple operating modes of the metal closed slot MCS, so the antenna of the present invention is a closed slot antenna. The wireless chip of the current laptop usually has two antenna terminals, namely the main antenna terminal (MAIN) and the auxiliary antenna terminal (AUX), so the two terminals can be connected to the main antenna excitation pattern 6 and the auxiliary antenna excitation pattern 7 respectively, to provide at least including but not limited to spatial diversity and multiple input multiple output characteristics and functions. Figure 3 The heat dissipation frame 5 has a plurality of openings 50 for allowing heat dissipation air to pass through.

[0038] refer to Figure 4, the main antenna excitation pattern 6 has a first feed point 61, and the first feed point 61 is connected to the first coaxial cable. The auxiliary antenna excitation pattern 7 has a second feed point 71, and the second feed point 71 is connected to the second coaxial cable. In order to simplify the drawing, the configuration of the first coaxial cable and the second coaxial cable is omitted in the figure. The central conductor of the coaxial cable is used to connect the antenna excitation pattern, and the outer conductor of the coaxial cable is grounded, such as grounding points A and B. Such a feeder connection method is a conventional technology and will not be described in detail. In other words, the above-mentioned first feed point 61 is connected to the central conductor of the first coaxial cable, and the outer conductor of the first coaxial cable is connected to point A. The connection system grounding is a conventional technical means and will not be described in detail. And preferably, the grounding design of the main antenna excitation pattern 6 usually has the effects of matching and increasing performance stability, but is not limited to this, and has functional differences according to actual conditions. The second feed point 71 is connected to the central conductor of the second coaxial cable, and the outer conductor of the second coaxial cable is connected to grounding point B. The connection system grounding is a conventional technical means and will not be described in detail. Preferably, the grounding design of the auxiliary antenna excitation pattern 7 usually has the effects of matching, increasing performance stability, etc., but is not limited to this, and has functional differences based on actual conditions. The above-mentioned coaxial cables can all be fastened to the heat dissipation frame 5 using a fastener, or even buried in a groove on the surface of the heat dissipation frame 5 to improve the stability of the component, but is not limited to this.

[0039] refer to Figure 5 and Figure 6 The heat dissipation frame 5 has a first outer side 51 and a second outer side 52, and the first outer side 51 and the second outer side 52 are perpendicular to each other. In addition, the second outer side 52 is provided with a plurality of first opening ends 501 for allowing heat dissipation airflow to pass through. Furthermore, the main antenna excitation pattern 6 and the auxiliary antenna excitation pattern 7 are both arranged on the first outer side 51, and the aforementioned first coaxial cable and the second coaxial cable are also arranged on the first outer side 51. The heat dissipation frame 5 further has a first inner side 53 and a second inner side 54, so that the first inner side 53 and the second inner side 54 are L-shaped, the first inner side 53 is parallel to the first outer side 51, and the second inner side 54 is parallel to the second outer side 52, wherein the second inner side 54 has a plurality of second opening ends 502, wherein the plurality of second opening ends 502 and the plurality of first opening ends 501 are used to connect the second inner side 54 and the second outer side 52 to each other, wherein the first inner side 53 is provided with a first grounding surface 531, and the second inner side 54 is provided with a second grounding surface 541. In this embodiment, the second ground plane 541 is a porous ground plane and corresponds to the shape of the plurality of second opening ends 502 .

[0040] Furthermore, the number, size, and shape of the second opening ends 502 on the second inner side 54 and the first opening ends 501 on the second outer side 52 can be different, as long as the opening 50 can pass through the second inner side 54 and the second outer side 52, and the number of the openings 50 needs to be plural. Fig. 9 and Fig.10 It can be seen that in this embodiment, two first opening ends 501 are grouped to correspond to one second opening end 502, so it can be seen that the number of opening ends on the second inner side 54 is half of the number of opening ends on the second outer side 52, that is, the number of second opening ends 502 is half of the number of first opening ends 501, but this is not limited. In another embodiment, the openings 50 on the second inner side 54 and the second outer side 52 can also be the same in number, size and shape, as long as a plurality of through holes can be achieved.

[0041] From the above, we can know that Figure 3 and Fig. 9 , Figure 3 It is a front view, and the front of the heat dissipation frame 5 (equivalent to the front of the antenna disposed in the heat dissipation port) has a plurality of openings 50 that are usually oriented toward the open space in the user's use state, such as at the connection near the shaft and away from the user. In other words, Figure 3 As a front view of the antenna, it is actually combined with the housing. Figure 1 When the laptop is in use mode, it is the side away from the user. Fig. 9 This is a perspective from outside the heat dissipation port, but in order to facilitate identification of the structure of the opening 50, the heat dissipation frame 5 is placed upside down, but the coordinate axes are consistent with the previous figure. Preferably, the main antenna excitation pattern 6 and the auxiliary antenna excitation pattern 7 can be protected with insulating paint. The first ground plane 531 is parallel to the main antenna excitation pattern 6 and the auxiliary antenna excitation pattern 7, wherein the main antenna excitation pattern 6 is further connected to the first exposed portion 521, and the first exposed portion 521 is arranged on the second outer side 52; wherein the auxiliary antenna excitation pattern 7 is further connected to the second exposed portion 522, and the second exposed portion 522 is arranged on the second outer side 52, wherein the second ground plane 541 is parallel to the first exposed portion 521 and the second exposed portion 522. In addition, in order to prevent the antenna component from being exposed to the outside of the laptop, the first exposed portion 521 and the second exposed portion 522 can be painted (and insulated) in accordance with the color of the heat dissipation frame 5 or the housing, for visual concealment or color beautification, but not limited to this.

[0042] Furthermore, Fig.10 This is a perspective from the inside of the heat dissipation port, that is, the back side of the heat dissipation frame 5 . It can be seen that grounding metal, that is, a porous second grounding surface 541 , is distributed around the second opening end 502 . Fig.10The heat dissipation frame 5 is placed upside down to facilitate identification of the structure of the opening 50, but the coordinate axes are consistent with the previous figure. The grounded metal around the second opening end 502 can offset the matching degree of the metal parts in the housing that affect the antenna excitation, which can improve the stability of the antenna performance and is not easily affected by other components (assemblies).

[0043] In terms of the function of the antenna, the laptop antenna with integrated heat dissipation port of the present embodiment is used in the frequency band specified by WiFi 6E, that is, the wireless local area network (WLAN) and the so-called 5G sub-6 band. For example, it includes the frequency range of 2.4GHz and 5100MHz-5900MHz, and even includes the frequency range from above 6GHz to 7.125GHz. The above frequency range is the wireless communication frequency band commonly used by laptops. For example, when the size of the metal closed slot MCS is known, the length of this I-shaped slot is about 308 mm (the distance between the first metal shaft 3 and the second metal shaft 4 is parallel to the X-axis), the width is about 15 mm (the gap between the first metal shell 1 and the second metal shell 2), and the height of the plurality of openings 50 is about 15 mm (the direction of the height is parallel to the Z-axis and is less than the thickness of the casing). After appropriately adjusting the structure of the main antenna excitation pattern 6, it can be obtained. Fig.11 The return loss diagram of the main antenna excitation pattern 6 in laptop mode is shown in FIG. Fig.12 The return loss diagram of the main antenna excitation pattern 6 in the closed mode is shown. Similarly, after properly adjusting the structure of the auxiliary antenna excitation pattern 7, it can be obtained Fig.13 The auxiliary antenna excitation pattern 7 shown in FIG. 7 is a return loss diagram in laptop mode. Fig.14 The return loss diagram of the auxiliary antenna excitation pattern 7 in the closed mode is displayed. In terms of antenna efficiency, for example, a laptop manufacturer can define that in laptop mode operation, the efficiency in the 2.4GHz band is between -4dB and -5dB, which is usable, and the efficiency in the frequency band above 5GHz is between -5dB and -6dB, which is usable. For closed mode operation, the efficiency in the 2.4GHz band is between -8dB and -9dB, which is usable, and the efficiency in the frequency band above 5GHz is between -9dB and -10dB, which is usable. The defined antenna efficiency specifications usually vary according to the performance, power consumption and communication specifications of the wireless chip. The efficiency value range described above is only applicable to examples available on the market, which can be understood by technicians in the field, so it will not be repeated.

[0044] In summary, the laptop antenna with integrated heat dissipation port provided by the embodiment of the present invention integrates the antenna into the heat dissipation port, and does not need to reserve an antenna window, thereby achieving a smaller antenna space and improving the degree of component integration. In addition, by utilizing the large space of the heat dissipation port, the shielding effect of the metal of the device body itself can be reduced, thereby improving the antenna performance. In particular, it is suitable for laptop products with a metal casing, and has a high industrial application value.
