Description

Radiating oscillator and antenna

Technical Field

The present invention relates to the field of wireless communications, and more particularly, to a radiating element and an antenna including the same.

Background

The radiation element and the support member of the conventional radiation oscillator are fixed to each other by welding or by other means such as rivet-riveting, but such fixing means are inconvenient and inefficient to operate, and when one of the components, such as the radiation element, is damaged, it is often necessary to replace the entire radiation oscillator instead of only the failed radiation element, which results in additional maintenance costs.

SUMMERY OF THE UTILITY MODEL

In view of the profound understanding of the problems in the background art, that is, the conventional radiation oscillator has a single fixing manner of the radiation element and the support member, is inconvenient to operate, and is not easy to repair, the inventors of the present invention have conceived to design a radiation oscillator with a changed fixing manner, which can significantly improve the assembly efficiency of the radiation oscillator and reduce the maintenance cost.

Specifically, a first aspect of the present invention provides a radiating element, including:

a radiating element configured to radiate a radio signal and provided with at least two fixing portions thereon, wherein each of the at least two fixing portions includes a joint portion; and

a support member configured to provide support for the radiation element and to feed the radiation element, wherein fixing engagement portions matching the fixing portions are respectively configured at least two of four end portions of the support member,

wherein, after assembly is complete, the engagement portion is located between two sub-portions of the fixed snap-fit portion.

In the radiation oscillator according to the present invention, since the fixation between the radiation element and the support member can be achieved by means of the cooperation between the fixation portion and the fixation engagement portion respectively included therein, without welding, the assembly manner thereof is greatly different from that of the conventional radiation oscillator, thereby making it possible to facilitate the improvement of the product assembly efficiency according to the radiation oscillator disclosed in the present invention. In addition, the radiation oscillator provided by the utility model adopts a combined and integrated structural form, so that the strength of the radiation oscillator can be effectively enhanced. Moreover, because the fixing mode is detachable, the maintenance cost of the radiation oscillator disclosed by the utility model can be greatly reduced.

In one embodiment according to the present invention, the fixing portion further includes a cantilever and a stopper portion, the fixing engaging portion abuts against the cantilever in a first assembled state so that the cantilever is deformed in a direction away from the support member, and in a second assembled state, the engaging portion is located between two sub-portions of the fixing engaging portion, the cantilever returns to a natural state and the fixing engaging portion abuts between the cantilever and the stopper portion.

In one embodiment according to the utility model, the first assembly state is switched to the second assembly state by rotating the radiating element relative to the support member. More preferably, in an embodiment according to the utility model, the at least two fixation parts are configured on a circumferential structure to enable switching between the first and second assembly state by rotational movement of the support member relative to the radiating element. In this way it is possible to switch between the first and the second assembly state in a rotational manner, so that the assembly and disassembly of the disclosed radiating element according to the utility model can be achieved in an advantageous manner.

Optionally, in an embodiment according to the utility model, the central position of the radiating element is configured to be provided with a circular hole for assembly positioning.

Preferably, in an embodiment according to the present invention, the cantilever is configured as a spring tongue piece, and in the second assembled state, the spring tongue piece and the stopper portion are located on both sides of the fixed engaging portion. Further preferably, in an embodiment according to the present invention, the latch piece structure is configured as a seesaw latch piece structure or a downward bend latch piece structure. More preferably, in an embodiment according to the present invention, the radiating element is further configured to be provided with an annular groove or a cross groove for setting the radio frequency performance of the radiating element.

Preferably, in an embodiment according to the present invention, four fixing portions are provided on the radiation element, and wherein fixing engagement portions matching the fixing portions are respectively configured at four ends of the support member.

Alternatively or additionally, in an embodiment according to the utility model, in the second assembled state, the end plane of the support member is in or beyond the plane of the radiating element. Preferably, in an embodiment according to the utility model, the support member is welded to a power dividing plate at its side remote from the radiating element.

Furthermore, a second aspect of the present invention proposes an antenna comprising: the radiating element according to the first aspect of the utility model; and a reflection plate, wherein the radiation vibrator is mounted on the reflection plate.

In summary, since the radiation element and the support member can be fixed by the cooperation between the fixing portion and the fixing engaging portion respectively included therein without welding, the assembly manner is greatly different from that of the conventional radiation oscillator, and thus the radiation oscillator disclosed by the present invention can facilitate the improvement of the product assembly efficiency. In addition, the radiation oscillator provided by the utility model adopts a combined and integrated structural form, so that the strength of the radiation oscillator can be effectively enhanced. Moreover, because the fixing mode is detachable, the maintenance cost of the radiation oscillator disclosed by the utility model can be greatly reduced.

Detailed Description

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings illustrate, by way of example, specific embodiments in which the utility model may be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments according to the utility model. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, to be taken in an illustrative rather than a limiting sense, and the scope of the present invention is defined by the appended claims.

The prior art has the technical problems that the existing fixing means are inconvenient and inefficient to operate and that there is a not economical maintenance cost when it is necessary to replace a certain part, such as a radiating element, in which a failure occurs.

In view of the above technical problems, the inventors of the present invention have devised a radiation oscillator with a modified fixing method, which can significantly improve the assembly efficiency of the radiation oscillator and reduce the maintenance cost.

The radiation oscillator proposed by the present invention will be described in detail below with reference to the accompanying drawings.

In order to solve the technical problem caused by the fact that the radiation element and the supporting member of the traditional radiation oscillator are usually fixed in a welding connection mode, the radiation element and the supporting member are fixed through the matching of the fixing portion and the fixing clamping portion, so that the welding fixing mode is not used, the assembly efficiency of the radiation oscillator can be obviously improved, and the maintenance cost can be reduced.

Specifically, fig. 1A shows a schematic diagram of a radiating element 110 according to an embodiment of the present invention, fig. 1B shows a schematic diagram of a support member 120 according to an embodiment of the present invention, and fig. 1C shows a perspective view of a radiating element 100 according to an embodiment of the present invention. As can be seen from fig. 1A, four fixing portions 111 are provided on the radiating element 110 of the radiating element 100, and each fixing portion 111 includes a cantilever 1111, a joint portion 1112, and a stopper portion 1113. Specifically, as shown in fig. 1A, the four fixing portions 111 are similar in structure, so that the structure of the radiation element 110 according to the present invention is described by taking only the fixing portion 111 at the lower right corner as an example. Furthermore, it should be understood that the four fixing portions 111 shown herein are merely exemplary and not restrictive, and that other numbers of fixing portions 111 are possible, such as having only two fixing portions 111 for fixing purposes, although other numbers, i.e., arrangements of a plurality of fixing portions 111 are also possible, as long as the radiation element 110 and the support member 120 can be fixed or detached in a detachable manner.

Here, it should be understood by those skilled in the art that the main inventive concept of the present invention lies in: because the radiation element and the support member can be fixed by means of the matching between the fixing part and the fixing clamping part which are respectively arranged on the radiation element and the support member without welding, the assembly mode of the radiation element is greatly different from that of the traditional radiation oscillator, and the radiation oscillator disclosed by the utility model can be beneficial to improving the assembly efficiency of products. Therefore, as long as the manufacturing tolerance between the fixing part and the fixing clamping part is matched properly, the fixing mode can be very flexible and can also be fixed relatively reliably. In other words, the suspension 1111 and the stopper 1113 are provided for further optimizing the fixing effect, and are not necessarily provided, which is a further improvement.

Alternatively or additionally, the middle portion of the radiating element 110 is configured to be provided with a cross slot. In this way, impedance matching and frequency band adjustment of the radiating element 100 can be facilitated. Further, the center position of the radiation element 110 is configured to be provided with a circular hole 112 for assembly positioning. The position of the circular hole 112 based on the positioning can assist, for example, a workpiece for mounting purposes, by virtue of the cooperation between the workpiece and the circular hole 112, so as to achieve rapid positioning of the radiation element 110 and the support member 120, thereby improving the assembly efficiency of the radiation vibrator 100 according to the present disclosure. Here, each of the fixing portions 111 has, for example, a circular arc shape, and has, for example, a rotationally symmetrical structure around the circular hole 112, and preferably, corresponding portions of the four fixing portions 111 are different by a rotation angle of 90 degrees, respectively.

Fig. 1B shows a support member 120 used in the disclosed radiation oscillator 100. Specifically, as shown in fig. 1B, the supporting member 120 according to the present disclosure includes two supporting

sub-members

121 and 122 orthogonal to each other. Here, the support sub-member 121 has one downward-facing groove 1213 (downward in the direction shown in fig. 1B) in its middle portion, and the support sub-member 122 also has one upward-facing groove 1223 (upward in the direction shown in fig. 1B) in its middle portion. In assembly, the slots of the support sub-member 121 are inserted through the slots of the support sub-member 122, i.e. the two

support sub-members

121 and 122 can be inserted into each other to form a cross-shaped support member 120. As can also be seen from fig. 1B, each supporting

sub-member

121 or 122 may be etched with an approximately inverted U-shaped metal film 1212, and the approximately inverted U-shaped metal film 1212 is configured to feed the radiating element 110 (shown in fig. 1A) in a coupling manner. In this way, an approximately inverted U-shaped metal copper foil is etched on the two

plates

121 and 122 to be inserted, thereby facilitating the coupling feeding of the radiating element 110 such as a horizontal square plate.

Furthermore, as can be seen from fig. 1B, each of the supporting

sub-members

121 or 122 may have a fixing and engaging portion 1211 at its end portion for matching with the fixing portion 111, and the fixing and engaging portion 1211 can include two sub-portions, i.e., a fixing and engaging sub-portion 1211a and a fixing and engaging sub-portion 1211B of the fixing and engaging portion 1211, which are disposed up and down, for example. Here, it should be understood that the example shown here in which each of the two side upper ends of the

support sub-members

121 or 122 is provided with one fixing engaging portion 1211 matching with the fixing portion 111 is merely exemplary and not restrictive, and it is also possible to provide two fixing engaging portions 1211 matching with the fixing portion 111 only at one end of one of the

support sub-members

121 or 122, or provide only one fixing engaging portion 1211 matching with the fixing portion 111 on each of the

support sub-members

121 or 122, respectively, as long as the radiation element 110 can be stably fixed to a structure (such as a printed circuit board PCB) fixed together with the support member 120 by means of the cross-shaped support member 120, such as by soldering or the like, for example. In other words, the support member 120 may be stably fixed to the PCB by soldering, etc., and then the radiation element 110 is mounted on the other end of the support member 120, thereby ensuring stable mounting of the radiation element 110.

In a specific assembly process, the two supporting

sub-members

121 and 122 may be inserted into each other to form a cross-shaped supporting member 120, and then the radiating element 110 is placed on the cross-shaped supporting member 120 to align the fixing portion 111 with the fixing and engaging portion 1211, at which time the fixing and engaging sub-portion 1211a will lift the cantilever 1111 upward to deform. At this time, if viewed from the top as shown in fig. 1A, the fixed engaging portion 1211 is below the cantilever 1111, but the engaging portion 1112 is not located between the fixed engaging sub-portion 1211A and the fixed engaging sub-portion 1211b, and the fixed engaging portion 1211 is not in contact with the cantilever 1111 and the stopper portion 1113.

At this time, if the radiation element 110 is rotated counterclockwise with respect to the support member 120 in a plan view, the radiation oscillator 100 can be switched from the first assembly state to the second assembly state shown in fig. 1C. In the second assembled state, that is, in the assembled state shown in fig. 1C, the engaging portion 1112 is located between the two fixed engaging sub-portions 1211a and 1211b of the fixed engaging portion 1211, the cantilever 1111 returns to the natural state, and the fixed engaging portion 1211 abuts between the cantilever 1111 and the stopper portion 1113. In the example shown in fig. 1A, 1B, and 1C, the cantilever 1111 is configured as a tongue piece, and in the second assembled state, the tongue piece and the stopper portion 1113 are located on both sides of the fixed engaging portion 1211. At this time, since the fixing engagement portion 1211 abuts between the cantilever 1111 and the stopper portion 1113, the radiation element 110 does not rotate in the clockwise or counterclockwise direction with respect to the support member 120; and in the other direction, i.e., the up-down direction, since the joint 1112 is located between the two fixed engaging sub-portions 1211a and 1211b of the fixed engaging portion 1211, the radiation element 110 does not move up and down with respect to the support member 120. Since the radiation element 110 is fixed to the support member 120 in both the clockwise or counterclockwise direction and the up-down direction, the radiation element 110 can be stably fixed to the support member 120.

Here, it is preferable that the interval between the two sub-portions 1211a and 1211b of the fixing engagement portion 1211 is associated with the thickness of the coupling portion 1112 or the thickness of the radiation element 110, and if the interval and the latter two thicknesses are exactly the same, more stable fixing can be achieved. It is further preferable that the spacing between the cantilever 1111 and the stopper portion 1113 is associated with the thickness of the supporting sub-member 121 or the supporting sub-member 122 of the supporting member 120, and if the spacing is exactly the same as the thickness of the latter, more stable fixation can be achieved.

In case a part needs to be replaced, the cantilever 1111 can be sucked up or jacked up, for example by means of a tool, while the radiating element 110 is rotated clockwise with respect to the support member 120, at which time the radiating element 110 can be separated from the support member 120. In general terms, the first assembly state is switched to the second assembly state or vice versa by rotating the radiating element 111 relative to the support member 120. In order to enable switching between the first and second assembly states in a rotational manner, the at least two fixing portions 111 are configured on a circumferential structure to enable switching between the first and second assembly states by rotational movement of the support member 120 relative to the radiating element 110. It will be appreciated by those skilled in the art that in the case of switching between the first assembled state and the second assembled state in other non-rotating manners, the fixing portions may not be on the same circumferential structure, and switching between the first assembled state and the second assembled state may also be achieved.

Furthermore, as can be seen from fig. 1C, the radiating element 100 further includes a power dividing plate 130, and the supporting member 120 is welded to the power dividing plate 130 on the side away from the radiating element 110, so as to couple and feed the signal on the power dividing plate 130 to the radiating element 110 via the metal thin film 1212 of the approximate inverted U-shape on the supporting member 120.

Other implementations of the disclosed radiating element according to the present invention will be described below with reference to fig. 2 to 5.

Fig. 2 shows an exploded view of a radiating element 200 according to another embodiment of the utility model. As can be seen in the radiation element 200 shown in fig. 2, the radiation element 200 comprises a radiation element 210, a support member 220 and a power dividing plate 230. As can be seen from fig. 2, four fixing portions 211 are provided on the radiating element 210 of the radiating element 200, and each fixing portion 211 includes a cantilever 2111, a coupling portion 2112, and a stopper portion 2113. Specifically, as shown in fig. 2, the four fixing portions 211 have similar structures, and therefore, the structure of the radiation element 210 according to the present invention is described by taking only the fixing portion 211 at the lower right corner as an example. Further, it should be understood that the four fixing portions 211 shown herein are merely exemplary and not limiting, and that other numbers of fixing portions 211 are possible, such as having only two fixing portions 211 for fixing purposes, of course, other numbers, i.e., a plurality of four fixing portions 211 are also possible, as long as the radiation element 210 and the support member 220 can be fixed or detached by a detachable manner.

As can be seen from fig. 2, the difference from the radiating element 100 shown in fig. 1C is that: the shape of the fixing portion 211 of the radiation oscillator 200 shown in fig. 2 is different from the shape of the fixing portion 111 of the radiation oscillator 100. In fig. 2, the plane of the cantilever 2111, the engaging portion 2112 and the limiting portion 2113 is lower than the plane of the radiating element 210, i.e., the radiating element 210 has a concave structure. Alternatively, the cantilever 2111 may be in a plane below the radiating element 210, or may be a slightly upturned structure. The assembly and fixing principle of the radiation oscillator 200 shown in fig. 2 according to the present invention are similar to the structure shown in fig. 1C, and therefore, the details are not repeated herein.

Fig. 3 shows an assembled view of a radiating element 300 according to yet another embodiment of the utility model.

Specifically, as shown in fig. 3, the four fixing portions 311 have similar structures, and therefore, the structure of the radiation element 310 according to the present invention is described by taking only the fixing portion 311 at the lower right corner as an example. Furthermore, it should be understood that the four fixing portions 311 shown herein are merely exemplary and not limiting, and that other numbers of fixing portions 311 are possible, such as having only two fixing portions 311 for fixing purposes, although other numbers, i.e., a plurality of four fixing portions 311, are possible, as long as the radiation element 310 and the support member 320 can be detachably fixed or detached.

As can be seen from fig. 3, the difference from the radiating element 100 shown in fig. 1C is that: the shape of fixing portion 311 of radiation oscillator 300 shown in fig. 3 is different from the shape of fixing portion 111 of radiation oscillator 100. The engaging portion 3112 and the limiting portion 3113 in fig. 3 are located on a plane lower than the plane of the radiating element 310, that is, the radiating element 310 has a concave structure. Alternatively, the fixed end of the cantilever 3111 may be in the plane of the radiating element 310 and the free end of the cantilever 3111 may be in a lower plane than the radiating element 310. In other words, the suspension 3111 may be configured as a kick-down tongue. The assembly and fixing principle of the radiation oscillator 300 shown in fig. 3 according to the present invention are similar to the structure shown in fig. 1C, and therefore, the details are not repeated herein.

Fig. 4 shows an exploded view of a radiating element 400 according to yet another embodiment of the utility model. As can be seen in the radiation element 400 shown in fig. 4, the radiation element 400 includes a radiation element 410, a support member 420, and a power dividing plate 430. As can be seen from fig. 4, four fixing portions 411 are provided on the radiating element 410 of the radiating element 400, and each fixing portion 411 includes a cantilever, a joint portion, and a stopper portion, respectively. Specifically, as shown in fig. 4, the four fixing portions 411 are similar in structure, so that the structure of the radiation element 410 according to the present invention is described by taking the fixing portion 411 at the lower right corner as an example. Further, it should be understood that the four fixing portions 411 shown herein are merely exemplary and not limiting, and that other numbers of fixing portions 411 are possible, such as having only two fixing portions 411 for fixing purposes, although other numbers, i.e., a plurality of four fixing portions 411, are possible as long as the radiation element 410 and the support member 420 can be fixed or removed in a detachable manner.

As can be seen from fig. 4, the difference from the radiating element 100 shown in fig. 1C is that: the radiating element 410 of the radiating element 400 shown in fig. 4 is also die cut with four sets of double-ring slots 415, and the four sets of double-ring slots 415 are arranged to facilitate adjustment of the radio frequency performance, lobe width, gain, and radiation pattern of the radiating element 400. The assembly and fixing principle of the radiating element 400 shown in fig. 4 according to the present invention are similar to those of the structure shown in fig. 1C, and therefore, the details are not repeated herein.

Fig. 5 shows an exploded view of a radiating element 500 according to yet another embodiment of the utility model. As can be seen in the radiation element 500 shown in fig. 5, the radiation element 500 comprises a radiation element 510, a support member 520 and a power dividing plate 530. As can be seen from fig. 5, four fixing portions 511 are provided on the radiating element 510 of the radiating element 500, and each fixing portion 511 includes a cantilever, a joint portion, and a stopper portion, respectively. Specifically, as shown in fig. 5, the four fixing portions 511 have similar structures, so that the structure of the radiation element 510 according to the present invention is described by taking the fixing portion 511 at the lower right corner as an example. Further, it should be understood that the four fixing portions 511 shown herein are merely exemplary and not restrictive, and that other numbers of fixing portions 511 are possible, such as having only two fixing portions 511 for fixing purposes, of course, other numbers, i.e., a plurality of four fixing portions 511 are also possible, as long as the radiation element 510 and the support member 520 can be fixed or detached in a detachable manner.

As can be seen from fig. 5, the difference from the radiating element 400 shown in fig. 4 is that: the shape of fixing portion 511 of radiation oscillator 500 shown in fig. 5 is different from the shape of fixing portion 411 of radiation oscillator 400. The plane of the engaging portion and the limiting portion in fig. 5 is higher than the plane of the radiating element 510, i.e., the radiating element 510 has a convex hull structure. Alternatively, the free end of the cantilever may be in the plane of the radiating element 510, while the engaging portion and the limiting portion are in a plane higher than the plane of the radiating element 510. At the same time, the fixing engagement portion of the support member 520 will also correspondingly extend beyond the plane in which the radiation element 510 is located, so as to achieve the cooperation with the convex hull structure described above, and thus achieve the fixing between the radiation element 510 and the support member 520. The assembly and fixing principle of the radiating element 500 shown in fig. 5 according to the present invention are similar to those of the structure shown in fig. 4, and therefore, the details are not repeated herein.

Furthermore, a second aspect of the utility model proposes an antenna comprising a radiating element according to the above aspect of the utility model and a reflector plate, wherein the radiating element is mounted on the reflector plate.

The advantage of the above-designed radiating element lies in the following aspects:

firstly, the employed coupling feed structure can extend the operating bandwidth of the antenna comprising the radiating element, and because the feed structure and the guiding structure can be coupled together, the radiating element thus formed is susceptible to stabilization of passive intermodulation.

In addition, a coupled feeding mode is adopted, so that the formed radiating element and the formed antenna can easily obtain higher isolation. And the adopted printed circuit board structure is easy to flexibly adjust S parameters such as the working frequency band, the working impedance and the like of the radiating oscillator and the formed antenna and the directional diagram electrical property, and the die opening time is saved. The radiation oscillator disclosed by the utility model adopts a four-point feeding structure, so that higher cross polarization, impedance matching and other electrical characteristics are easily obtained. The support member is combined and formed in a direct insertion mode, and comprises a four-point coupling feed and support structure of a vertical part, and a sheet metal part is arranged at a horizontal part.

In summary, in the radiation oscillator according to the present invention, since the fixing between the radiation element and the support member can be achieved by the cooperation between the fixing portion and the fixing engaging portion respectively included therein, without welding, the assembling manner thereof is greatly different from that of the conventional radiation oscillator, thereby making it possible to facilitate the improvement of the product assembling efficiency of the radiation oscillator according to the present invention. In addition, the radiation oscillator provided by the utility model adopts a combined and integrated structural form, so that the strength of the radiation oscillator can be effectively enhanced. Moreover, because the fixing mode is detachable, the maintenance cost of the radiation oscillator disclosed by the utility model can be greatly reduced.
