Description
Technical Field
The application relates to the field of communication, in particular to an antenna structure assembly.
Background
Nowadays, the functional requirements of electronic products for wireless communication are increasing, and a plurality of antennas may be disposed in one product, but signal interference is easily generated between the antennas. Therefore, isolation of the antenna becomes a key for wireless communication today. In the past, the following methods exist for improving the isolation of the antenna, the simplest way is to directly increase the distance between adjacent antennas, and the isolation of the antenna can be improved along with the increase of the adjacent distances. However, within the limited size of the product, there is often no provision for an antenna margin, so there are practical limitations.
Secondly, some documents propose to design the two adjacent antennas with different polarizations, thereby reducing mutual electromagnetic field interference. However, due to the different polarizations of the two adjacent antennas, the side effect of the overall radiation efficiency degradation is easily caused. Furthermore, a quarter-wavelength Isolator (Isolator) can be added between the two antennas, but under the same size, the addition of the Isolator can improve the isolation of the adjacent antennas, but the original characteristics of the antennas can be affected, so that the communication quality of the product received by long-distance propagation is reduced.

Detailed Description
In the drawings, the widths of portions of elements, regions, etc. are exaggerated for clarity. Like numbers refer to like elements throughout. It will be understood that when an element is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present.
It will be understood that, although the terms "first," "second," "third," etc. may be used herein to describe various elements, components, regions or sections, these elements, components, regions and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a "first element," "component," "region," or "section" discussed below could be termed a second element, component, region, or section without departing from the teachings herein.
Moreover, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe one element's relationship to another element as illustrated. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on the "upper" side of the other elements. Thus, the exemplary term "lower" may include both "lower" and "upper" orientations, depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" other elements would then be oriented "above" the other elements. Thus, the exemplary terms "below" or "beneath" can encompass both an orientation of above and below.
Fig. 1 is a perspective view of a first embodiment of an antenna structure assembly. Fig. 2 is a schematic top view of a first embodiment of an antenna structure assembly. As shown in fig. 1 and 2, the antenna structure assembly 1 of the first embodiment includes a first antenna 10, a second antenna 20, a conductive shielding wall 30, and a connection portion 40. A portion of each of the first antenna 10 and the second antenna 20 is disposed on the ground plate 100 and extends upward of the ground plate 100. The second antenna 20 is adjacent to the first antenna 10, and a first gap G1 is provided between the first antenna 10 and the second antenna 20, wherein a width d1 of the first gap G1 is 1/40 to 1/2, preferably 1/10 to 1/4, of a wavelength corresponding to the highest operating frequency. The conductive shielding wall 30 is adjacent to the grounding plate 100, and a second gap G2 is provided between the conductive shielding wall 30 and the grounding plate 100, wherein the width d2 of the second gap G2 ranges from 1/40 to 1/2, preferably from 1/10 to 1/4, of the wavelength corresponding to the highest operating frequency. Here, the operating frequency bands of the first antenna 10 and the second antenna 20 may correspond to the frequency bands of LTE, wifi, GPS, ultra-bandwidth, sub6GHz, mmWave, etc., and the width d1 of the first gap G1 may be adjusted by the wavelength corresponding to the highest frequency corresponding thereto. In general, the highest operating frequency corresponds to a wavelength of 1 to 15mm, for example, 2 to 8mm. Preferably, the width d1 of the first gap G1 is less than 5mm.
In the first embodiment, the extending directions of the conductive shielding wall 30, the first antenna 10, and the second antenna 20 in the longitudinal direction are substantially parallel to the normal direction of the grounding plate 100, and the first antenna 10 and the second antenna 20 may be projected onto the conductive shielding wall 30. The connection portion 40 connects the conductive shield wall 30 and the ground plate 100, and is located between the first antenna 10 and the second antenna 20. However, the above is merely exemplary and is not intended to be limiting. For example, the conductive shielding wall 30, the first antenna 10, and the second antenna 20 may not be parallel, but may be at least partially overlapped on the projection plane. In addition, the height H of the conductive shielding wall 30 is greater than or equal to 1/2 of the height H of the first antenna 10 or the second antenna 20, and the length L of the conductive shielding wall 30 is greater than or equal to 1/2 of the total length of the first antenna 10 and the second antenna 20. Therefore, the effect of metal shielding is achieved, the interference of external signals is reduced, and the isolation of the two antennas is effectively improved.
Fig. 3 is a schematic perspective view of a second embodiment of an antenna structure assembly. As shown in fig. 3, referring also to fig. 1, the second embodiment differs from the first embodiment in that the conductive shield wall 30 has an opening 35 therein. In the drawings, the conductive shielding wall 30 may be a mesh structure having a plurality of openings 35, however, this is only an example and not intended to be limiting. In practice, the conductive shielding wall 30 may be perforated, grooved, or made of porous conductive foam or conductive cloth. Thus, the functions of adding the first antenna 10 and the second antenna 20 can be achieved through the holes when the metal shielding effect is achieved. Meanwhile, the ventilation and heat dissipation effects of the whole element can be improved. Further, an opening 45 may be provided in the connecting portion 40.
Fig. 4 is a schematic perspective view of a third embodiment of an antenna structure assembly. Fig. 5 is a schematic side view of a third embodiment of an antenna structure assembly. As shown in fig. 4 and 5, referring to fig. 1 and 2, the difference between the third embodiment and the first embodiment is that the connection portion 40 is not directly connected to the ground plate 100, and is electrically connected by capacitive coupling. In more detail, the connection portion 40 is located above the ground plate 100, a third gap G3 is provided between the connection portion 40 and the ground plate 100, and a width d3 of the third gap G3 is less than 1/100 of a wavelength corresponding to the highest operating frequency.
Further, as shown in fig. 4 and 5, the second gap G2 between the conductive shielding wall 30 and the ground plate 100 and/or the third gap G3 between the connection portion 40 and the ground plate 100 may be filled with the dielectric material 50. The capacitance is increased by the dielectric properties of the dielectric material 50, thereby increasing the effect of capacitive coupling.
Fig. 6 is a perspective view of a fourth embodiment of an antenna structure assembly. Referring to fig. 6 together with fig. 1, the fourth embodiment provides a plurality of connection portions 40A, 40B, 40C between the conductive shielding wall 30 and the ground plate 100, wherein the first connection portion 40A is adjacent to the first antenna 10, the second connection portion 40B is adjacent to the second antenna 20, and the third connection portion 40C is located between the first antenna 10 and the second antenna 20. However, this is merely an example and is not limited thereto, and in practice, more connection portions may be provided, and the first connection portion 40A, the second connection portion 40B, and the third connection portion 40C may be provided between the first antenna 10 and the second antenna 20.
Fig. 7 is a schematic perspective view of a fifth embodiment of an antenna structure assembly. Referring also to fig. 1, as shown in fig. 7, in a fifth embodiment, the conductive shield wall 30 further includes an extension 37. An extension 37 extends from the upper edge of the conductive shield wall 30. The length of the extension 37 is less than or equal to 1/4 of the wavelength corresponding to the highest operating frequency. Generally, the height H of the conductive shielding wall 30 with the extension portion 37 is higher than the height H of the first antenna 10 or the second antenna 20, and the extension portion 37 can shield the first antenna 10 or the second antenna 20 to reduce interference of external signals and improve isolation between the first antenna 10 and the second antenna 20. In fig. 7, the extension 37 extends toward the first antenna 10 or the second antenna 20, but actually extends opposite to the first antenna 10 or the second antenna 20, which also has the effect of improving the isolation.
Fig. 8 is a schematic perspective view of a sixth embodiment of an antenna structure assembly. As shown in fig. 8, the antenna structure assembly 1 of the sixth embodiment is different from the previous embodiment in the design of the conductive shielding wall 30 and the connection portion 40, and the sixth embodiment includes a first conductive shielding wall 30A, a second conductive shielding wall 30B, a first connection portion 40A and a second connection portion 40B. The first conductive shielding wall 30A is located at one side of the first antenna 10 and partially overlaps the first antenna 10 on the projection plane. The second conductive shield wall 30B partially overlaps the second antenna 20 on the projection plane. The first connection portion 40A connects the ground plate 100 and the first conductive shielding wall 30A, the second connection portion 40B connects the ground plate 100 and the second conductive shielding wall 30B, and the first connection portion 40A and the second connection portion 40B are located between the first antenna 10 and the second antenna 20.
In more detail, the first conductive shielding wall 30A and the second conductive shielding wall 30B have a fourth gap G4 therebetween, and the width d4 of the fourth gap G4 is smaller than the width d1 of the first gap G1, and generally, the width d4 of the fourth gap G4 ranges from 1/40 to 1/6, preferably from 1/20 to 1/10, of the wavelength corresponding to the highest operation frequency.
Fig. 9 is a schematic perspective view of a seventh embodiment of an antenna structure assembly. Fig. 10 is a schematic perspective view of an eighth embodiment of an antenna structure assembly. As shown in fig. 9 and 10, referring to fig. 1 and also to the seventh and eighth embodiments, the first antenna 10 and the second antenna 20 are respectively disposed on the first edge 100A and the second edge 100B of the ground plane 100, and the first edge 100A and the second edge 100B are substantially orthogonal, and in this case, substantially refer to allowing a necessary deviation, for example, the first edge 100A and the second edge 100B may be increased/decreased by 15 degrees in the orthogonal range. The conductive shielding wall 30 is L-shaped, and two bent portions are adjacent to the first antenna 10 and the second antenna 20, respectively. However, this is merely an example, and not limited thereto, and the conductive shielding wall 30 may be bent at an acute angle or an obtuse angle as long as it is satisfied that the conductive shielding wall 30, the first antenna 10, and the second antenna 20 at least partially overlap on the projection plane. In addition, the connection portion 40 may be disposed on the first edge 100A as in fig. 9, or may be disposed on the second edge 100B as in fig. 10. It should be noted that the connection portion 40 must be disposed between the first antenna 10 and the second antenna 20. However, this is by way of example only and not by way of limitation. In practice, a plurality of connection portions 40 may be provided as shown in fig. 6.
Fig. 11 is a perspective view of a ninth embodiment of an antenna structure assembly. Fig. 12 is a perspective view of a tenth embodiment of an antenna structure assembly. Referring to fig. 11 and 12, referring to fig. 8, 9, the ninth embodiment and the tenth embodiment, like the embodiment of fig. 8, the first conductive shielding wall 30A, the second conductive shielding wall 30B, the first connection portion 40A and the second connection portion 40B, and like the embodiment of fig. 9, the first antenna 10 and the second antenna 20 are respectively disposed at the first edge 100A and the second edge 100B of the ground patch 100, the first connection portion 40A is connected to the ground patch 100 and the first conductive shielding wall 30A, the second connection portion 40B is connected to the ground patch 100 and the second conductive shielding wall 30B, and the first connection portion 40A and the second connection portion 40B are disposed between the first antenna 10 and the second antenna 20.
As shown in the tenth embodiment of fig. 12, the first conductive shielding wall 30A and the second conductive shielding wall 30B further include an extension 37. The extension 37 extends from the upper edges of the first and second conductive shielding walls 30A and 30B toward the first and second antennas 10 and 20, respectively, to shield the tops of the first and second antennas 10 and 20. It should be understood that one or more conductive shielding walls 30 may be provided, and the conductive shielding walls 30 corresponding to the first antenna 10 and the second antenna 20 must be provided with a connection portion 40 connected to the ground plate 100, so as to improve the isolation between the first antenna 10 and the second antenna 20. In addition, the total length of the conductive shielding wall 30 should be greater than 1/2 of the total length of the first antenna 10 and the second antenna 20. The connection 40 may be provided with one or more, but at least one must be provided between the first antenna 10 and the second antenna 20. Similarly, in fig. 11 and 12, the extending directions of the first conductive shielding wall 30A and the second conductive shielding wall 30B are shown as being substantially orthogonal, but this is only an example and not limited thereto, and the extending directions of the first conductive shielding wall 30A and the second conductive shielding wall 30B may also form an acute angle or an obtuse angle, so long as the first antenna 10 and the first conductive shielding wall 30A overlap partially in a projection plane, and the second antenna 20 and the second conductive shielding wall 30B overlap at least partially in another projection plane.
Fig. 13 is a perspective view of an eleventh embodiment of an antenna structure assembly. As shown in fig. 13, the conductive shield wall 30 of the antenna structure assembly 1 of the eleventh embodiment is located above the ground plate 100, and the conductive shield wall 30 is connected to the ground plate 100 through the connection portion 40. In other words, the conductive shielding wall 30 may be disposed outside the first antenna 10 and the second antenna 20, or may be disposed inside the first antenna 10 and the second antenna 20. As such, the conductive shield wall 30 is more optional in the design of the overall electronic device.
Fig. 14 is a wave frequency chart of a comparative example. Fig. 15 is a wave frequency diagram of the antenna structure assembly. As shown in fig. 14, fig. 14 shows a spectrum measured by the first antenna 10 and the second antenna 20 without the conductive shield wall 30 and the connection portion 40. The lower curve in fig. 14 shows the signal response of the first antenna 10 and the second antenna 20, respectively, while the upper curve shows the signal strength at which the second antenna 20 receives the first antenna 10.
Fig. 15 is a spectrum diagram measured by the embodiment of fig. 1, and the width d1 of the first gap G1 is designed to be 5mm. Referring to fig. 14, the lower curve has no significant change, and the conductive shield wall 30 and the connection portion 40 are added, which means that the impedance and the frequency response of the first antenna 10 and the second antenna 20 have no significant influence. However, the upper curve moves down, which means that the signal strength of the second antenna 20 received by the first antenna 10 is greatly reduced, that is, the isolation between the first antenna 10 and the second antenna 20 is greatly improved.
In the prior art, it is generally considered that the metal shield reduces electromagnetic radiation and increases the path of electrostatic discharge to reduce the antenna function, which seriously affects the user experience in wireless communication applications, and the closer the metal shield is to the antenna, the more serious the antenna is. Therefore, the antenna is not designed to be adjacent to the housing or the metal wall. However, the present application overcomes the prior art bias by the conductive shield wall 30, the connection portion 40, and the second gap G2 between the conductive shield wall 30 and the ground plate 100.
In summary, in the above embodiment, the second gap G2 is formed between the conductive shielding wall 30 and the grounding plate 100, and the conductive shielding wall 30 and the grounding plate 100 are connected through the connection portion 40 between the first antenna 10 and the second antenna 20, so that the antenna structure assembly 1 can maintain the antenna characteristics even when the width d1 of the first gap G1 between the first antenna 10 and the second antenna 20 is smaller than 10mm, and further improve the isolation between the first antenna 10 and the second antenna 20, so that the antenna structure assembly 1 is suitable for various electronic communication devices.
Although the present application has been described with reference to the preferred embodiments, it should be understood that the application is not limited thereto, but rather, it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit of the application.
