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 application will be described in detail below with reference to the embodiments with reference to the attached drawings.

When the electronic device is a metal body, the antenna is shielded, and a hole needs to be formed in the metal body. In the related art, although the hole can be covered by the plastic with the same color in the electronic device, the overall appearance of the electronic device is affected due to the difference in texture and color between the metal and the plastic.

Based on the above defect, the present application provides an antenna module, which can be applied to an electronic device without changing the mechanism of the metal body of the electronic device to realize an antenna.

It should be noted that the electronic devices proposed in the present disclosure may include, but are not limited to, various types of terminal devices, such as a television, a sound box, an air conditioner, a fan, and the like, which employ a metal body. The following embodiments illustrate an electronic device as a television.

Referring to fig. 1, a schematic structural diagram of an antenna module according to an embodiment of the present application is shown.

As shown in fig. 1, the antenna module 10 includes:

the conductive shell 11 is partially provided with a plurality of hollow-out gaps;

the first slot antenna 12, the first slot antenna 12 includes a first slot 121, the first slot 121 is disposed in at least one hollow slot, a length of the first slot 121 is determined by a transceiving frequency band of the first slot antenna 12, and the first slot antenna 12 is configured to transceive at least one frequency band.

In particular, the partially conductive housing 11 may be a portion of an electronic device, and may be, for example, a portion of a bezel or a back case of a television. The conductive housing 11 may be a metal housing.

In some embodiments, the hollow gap may be a heat dissipation hole (disposed on the heat dissipation plate) or a sound output hole (disposed on the sound output plate) disposed on the television, and is used for heat dissipation or sound output of the television, which is not limited herein. It should be noted that, according to actual needs, the hollow gap can be set at any position of the television.

The shape and length of the hollow gap are determined by the shape and length of the heat dissipation hole or sound output hole of the television. It can be understood that the shape of the plurality of heat dissipation holes and the shape of the sound outlet may be the same or different. The following embodiments take the hollow gap as a heat dissipation hole and the conductive housing 11 as a heat dissipation plate as an example.

As shown in fig. 2, the heat dissipation plate 11 may include a plurality of rectangular hollow slits arranged side by side, and the sides of the plurality of rectangular hollow slits are connected by the connection plates 111 at two ends of the hollow slits. The length of the rectangular hollow gap is equal to the distance between the connection plates 111 at the two ends. It should be noted that, since the width of the slot has a relatively small influence on the resonance of the antenna, the width of the hollowed-out slot may be determined by the requirement of Industrial Design (ID) or heat dissipation.

As shown in fig. 3 to 5, the heat dissipation plate 11 may include a plurality of concentric ring-shaped slits, and the edges of the plurality of concentric ring-shaped slits are connected by at least one connection plate 111. It is understood that the annular hollow slit includes, but is not limited to, a circular slit, an elliptical slit, and a square slit.

If the sides forming the plurality of concentric annular hollow slits are connected by one connecting plate 111, the length of each concentric annular hollow slit is equal to the length between the connecting plates 111 at the two ends of each annular slit. If the edges forming the concentric annular hollow-out slits are connected by at least two connecting plates 111, the connecting plates 111 may be in the shape of a straight line (as shown in fig. 3), a cross (as shown in fig. 4), a meter (as shown in fig. 5), or a combination thereof

The type (not shown in the figures) may be other irregular shapes, etc., and the disclosure is not limited thereto. It can be understood that, if the sides forming the concentric annular hollow slits are connected by at least two connecting plates 111, the length of each concentric annular hollow slit is equal to the length between the two connecting plates 111 at the two ends of the respective annular slit.

In the following embodiments, a plurality of rectangular hollow slits are arranged side by side on the heat dissipation plate in fig. 2 as an example.

The first slit may be any slit provided in the heat dissipation plate 11. The first slot 121 implements the first slot antenna 12 according to the principle of slot antennas.

It should be noted that the first slot antenna 12 may be a 2.4G antenna, a 5G antenna, a Sub-6G antenna, a bluetooth antenna, or the like. The transceiving frequency band realized by the first slot antenna may be determined by the length of the first slot.

In this embodiment, the slot antenna is implemented by using the hollow-out slot of the conductive housing of the electronic device, that is, when the slot antenna is formed on the electronic device of the metal body, no additional slot or reserved plastic area is needed on the body, so that the structural integrity of the metal body is ensured, and the implementation is relatively simple. In addition, dielectric loss of plastic and the like does not exist in the area for realizing the antenna in the embodiment, and the efficiency of the antenna is high.

Because the receiving and transmitting frequency band of the antenna is related to the length of the hollow gap, the length of the hollow gap which is already arranged in the electronic device, such as a television, does not necessarily exactly meet the length corresponding to the receiving and transmitting frequency band of the antenna, and therefore, when the length of the hollow gap is too long, a part of the hollow gap needs to be blocked (as shown in fig. 6); when the lengths of the hollow-out slits are not long enough, the adjacent hollow-out slits need to be connected to increase the length (as shown in fig. 7).

In an embodiment, the first slot 121 is disposed in a hollow slot, if the length of the hollow slot is greater than the length corresponding to the transceiving frequency band of the first slot antenna 12, the first slot antenna 12 further includes a first conductive blocking plate 122, the first conductive blocking plate 122 is disposed at least one end of the hollow slot, and the length of the first conductive blocking plate 122 is a difference between the length of the hollow slot and the length corresponding to the transceiving frequency band.

Specifically, the first conductive blocking plate 122 may be made of the same material as the heat dissipation plate 11, or may not be made of the same material, which is not limited in the present disclosure.

It is understood that the first conductive blocking plate 122 may be disposed at either end of the first slit 121.

Assuming that the required slot length corresponding to the transceiving frequency band of the first slot antenna is approximately 60mm, and the length of the hollow slot is 80mm (i.e. the length of the first slot is also 80 mm), the length of the first conductive blocking plate 122 is 20mm.

In one embodiment, the first slot antenna 12 is disposed in at least two hollow slots, and the at least two hollow slots are connected to each other.

Specifically, two at least fretwork gaps are arbitrary two at least fretwork gaps in the heating panel 11, can be adjacent two at least fretwork gaps, also can be nonadjacent two at least fretwork gaps, and this disclosure does not limit this, as long as communicate each other between these two at least fretwork gaps can.

On the basis of the above embodiment, if the length of one hollow gap is smaller than the length corresponding to the transceiving frequency band of the first slot antenna, the first slot antenna 12 further includes at least one communicating component 123, and the communicating component is used for communicating at least two hollow gaps.

Specifically, the communicating component 123 can communicate one end or two ends of at least two hollow gaps, and also can communicate the middle portions of at least two hollow gaps, which is not limited in the present disclosure. The communicating component 123 in fig. 7 enables the two ends of the two hollow slits to communicate.

On the basis of the above embodiment, the first slot antenna 12 further includes a second conductive blocking plate 124, and the length of the second conductive blocking plate 124 is the difference between the sum of the lengths of the at least two hollow slots that are communicated with each other and the length corresponding to the transceiving frequency band.

Specifically, the second conductive blocking plate 124 may be made of the same material as the heat dissipation plate 11, or may not be made of the same material, which is not limited in the present disclosure.

It can be understood that the second conductive plugging plate 124 may be disposed at any end of the hollow gap, and may also be disposed in the middle of the hollow gap, which is not limited by the present disclosure.

Assuming that the length of the approximately required slot corresponding to the transceiving frequency band of the first slot antenna is 60mm, and the length of the hollow slot is 40mm, when the first slot antenna is disposed in the two hollow slots, the length of the second conductive blocking plate 124 is 20mm. It is understood that, in practice, as shown in fig. 7, since at least one communication member 123 is required to communicate with the two hollow gaps, the length of the second conductive blocking plate 124 may be slightly greater than 20mm to compensate for the length of the communication member 123.

Since adjacent slots have a certain influence on the antenna, the slots near the antenna need to be made as dummy slots. It should be noted that the dummy slit is to block a part of the slit and leave a hole on a part of the slit to ensure the flow of air, so as not to affect the heat dissipation of the television.

In some embodiments, as shown in fig. 8, at least one second slit 125 is disposed at both sides of the first slit 121, and a third conductive blocking plate 126 is disposed in each second slit 125. Optionally, at least two third conductive plugging plates 126 are disposed in each second slit 125. At least two third conductive plugging plates 126 may be disposed at equal intervals. The thickness of the third conductive blocking plate 119 is smaller than that of the heat dissipation plate 11.

Specifically, the second slot 125 may refer to an adjacent slot of the first slot 121, and the adjacent slot refers to a slot within a threshold distance range from the first slot 121, where the threshold distance range may be set according to actual requirements, for example, may be set according to a distance affecting the antenna.

The third conductive blocking plate 126 may be made of the same material as the heat dissipation plate 11, or may not be the same material as the heat dissipation plate, which is not limited in the disclosure.

For example, assuming that the thickness of the heat dissipation plate 11 is 1mm, the thickness of the third blocking plate 119 may be set to 0.5mm. And a third conductive plugging plate 126 is provided every 3 mm. It should be noted that the length of the third conductive blocking plate 126 can be set according to practical requirements, as long as it is not too long, for example, the length of the third conductive blocking plate 126 is not more than 10mm.

In this embodiment, by disposing a plurality of conductive blocking plates in the adjacent gap-the second gap of the first gap, the problem of influence of the adjacent gap on the antenna can be solved, and the antenna is not affected, and meanwhile, the electronic device, for example, the air circulation of the television is not affected, i.e., the heat dissipation of the television is not affected.

It should be noted that the method for processing the mutual influence of the adjacent slots in this embodiment can be widely applied to the slot antenna.

In some embodiments, the first slot antenna 12 further includes a first feeding point and a first loop back point, which are respectively disposed at 1/4-1/3 of two sides of the first slot 121, and are configured to transceive wireless signals in the first frequency band and the second frequency band; wherein the first frequency band is different from the second frequency band.

Specifically, when the length of the first slot satisfies the requirement for implementing dual-band, feeding is performed between the first feeding point and the first return point, so that a dual-band antenna can be implemented in one slot. For example, when the length of the first slot is 60mm, the positions of the first feeding point and the first return point are adjusted, and the resonance is adjusted through the feed-back matching circuit, so that the wifi 2.4g +5g dual-frequency antenna can be realized by one slot. Wherein, 2.4G wifi utilizes a wavelength resonance mode of the slot antenna, and 5G wifi utilizes 2 wavelength resonance modes of the slot antenna.

Fig. 9 is a graph of simulation results of a wifi 2.4g +5g dual-frequency antenna implemented by using the above embodiment scheme. It can be seen that both 2.4G and 5G achieve high efficiency and wide bandwidth.

As shown in fig. 10, it shows another schematic structural diagram of the antenna module. The antenna module 10 further includes a second slot antenna 13, the second slot antenna 13 includes a third slot 131, and the third slot antenna 131 is also disposed in at least one hollow slot.

Specifically, in order to realize that one television can meet various antenna modes, various antennas can be realized by utilizing the lengths of different hollow-out gaps.

It should be noted that, assuming that all the hollow-out gaps on the heat dissipation plate and/or the sound output plate in one television are the same, the embodiment of the present disclosure is adopted to block the overlong gap to reduce the length of the hollow-out gap or connect the adjacent hollow-out gaps to increase the length of the hollow-out gap, thereby implementing a plurality of antenna modes by using different lengths of the hollow-out gaps.

On the basis of the above embodiment, the shape of the hollow gap can be rectangular or annular.

Specifically, as indicated in the above embodiments, the shape of the hollow slits is determined according to the structural layout of the heat dissipating plate and/or the sound output plate. The shape of the hollow gap can be rectangular or annular.
