Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0039] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0040] In the related art, when installing the antenna, an outer cover is usually used to cover the antenna to achieve the purpose of beautifying the antenna. However, in order to meet the requirements of wide bandwidth, the traditional antenna will increase the distance between the metal patch in the antenna and the floor or overlap multiple metal patches.

[0041] Therefore, the antenna manufactured by the above method will have the problem of a higher antenna profile, which will increase the size required for the outer cover, limit the concealment of the beautification antenna installation, and reduce the beautification antenna effect.

[0042] Therefore, the embodiment of the present application provides a miniaturized beautified antenna, which covers the antenna body by setting a beautified cover and an antenna body; the antenna body includes a dielectric substrate, a floor, a microstrip patch resonator, a substrate integrated waveguide resonator and a feeding element; the microstrip patch resonator and the substrate integrated waveguide resonator are combined and arranged on the same side of the dielectric substrate, the floor is correspondingly arranged on the other side of the dielectric substrate, and the feeding element is arranged on the substrate integrated waveguide resonator; therefore, when working, the external signal is coupled to the substrate integrated waveguide resonator through the feeding element, and then coupled and transmitted to the microstrip patch resonator, exciting the microstrip patch resonator. The patch resonator resonates to achieve dual-mode resonance characteristics, so that the bandwidth is effectively widened, so that space can be effectively utilized, and the bandwidth is widened without increasing the overall size of the antenna, making the antenna structure more compact and low-profile, reducing the size of the required beautification cover, and optimizing the beautification antenna effect; in addition, the electric and magnetic hybrid coupling between the microstrip patch resonator and the substrate integrated waveguide resonator will produce a radiation zero point, thereby achieving filtering performance. Therefore, the problem that the antenna in the prior art has a high profile when meeting the requirements of wide bandwidth, resulting in poor use effect of the beautification antenna is solved.

[0043] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a miniaturized beautifying antenna, including a beautifying cover 100 and an antenna body 200, wherein the beautifying cover 100 covers the antenna body 200; the antenna body 200 includes a dielectric substrate 210, a floor 220, a microstrip patch resonator 230, a substrate integrated waveguide resonator 240 and a feeding element 250; the microstrip patch resonator 230 and the substrate integrated waveguide resonator 240 are combined and arranged on the same side of the dielectric substrate 210, the floor 220 is correspondingly arranged on the other side of the dielectric substrate 210, and the feeding element 250 is arranged on the substrate integrated waveguide resonator 240.

[0045] It should be noted that, in actual installation, the antenna body 200 can be fixed to the installation surface, and then the beautification cover 100 can cover the antenna body 200. At this time, the beautification cover 100 can be connected to the installation surface or to the antenna body 200. In actual operation, the outer surface of the beautification cover 100 can be painted with paint of the same color as the installation surface, thereby achieving the purpose of beautifying the antenna and increasing concealment.

[0046] The antenna body 200 includes a dielectric substrate 210, a floor 220, a microstrip patch resonator 230, a substrate integrated waveguide resonator 240, and a feeder 250. The dielectric constant of the dielectric substrate 210 can vary within a range of 1 to 20, and the thickness can be selected according to actual needs, without any other restrictions; in addition, the dielectric substrate 210 can also be replaced by an air medium.

[0047] The dielectric substrate 210 is arranged horizontally, and the microstrip patch resonator 230 and the substrate integrated waveguide resonator 240 are both attached to the upper surface of the dielectric substrate 210, and there is a gap between the microstrip patch resonator 230 and the substrate integrated waveguide resonator 240, so that the two are distributed at intervals. The microstrip patch resonator 230 and the substrate integrated waveguide resonator 240 can be circular, polygonal or other shapes, and both can be made of copper, aluminum, silver or other materials, without limitation.

[0048] The feeding element 250 is disposed on the SIV resonator 240 , and the feeding element 250 is used to be connected to an external circuit to supply power to the antenna body 200 .

[0049] The floor 220 is attached to the lower surface of the dielectric substrate 210. The size of the floor 220 is consistent with the size of the dielectric substrate 210, so that the edges of the two are flush. The floor 220 can be made of copper, aluminum or other materials. The floor 220 provides a ground reference and shielding function, enhancing the electromagnetic compatibility and stability of the entire system.

[0050] When working, the external signal is coupled to the substrate integrated waveguide resonator 240 through the feeding element 250, and the substrate integrated waveguide resonator 240 generates a strong electromagnetic wave at the resonance frequency. Then the electromagnetic wave is coupled and transmitted to the microstrip patch resonator 230, exciting the microstrip patch resonator 230 to resonate, thereby realizing the dual-mode resonance characteristic, so that the bandwidth is effectively widened, so that the space can be effectively utilized, and the bandwidth is widened without increasing the overall size of the antenna, so that the antenna structure is more compact and the profile is low, the size of the required beautification cover 100 is reduced, and the use effect of the beautification antenna is optimized.

[0051] In addition, the electric and magnetic hybrid coupling between the microstrip patch resonator 230 and the substrate integrated waveguide resonator 240 will produce a radiation zero point, thereby achieving filtering performance. Therefore, the problem that the antenna in the prior art has a high profile when meeting the requirements of wide bandwidth, resulting in poor use effect of the beautified antenna is solved.

[0052] like Figure 2 As shown, in some embodiments, the antenna structure further includes a feed line 300 , one end of the feed line 300 is connected to the feed element 250 , and the other end of the feed line 300 passes through to the outside of the beautification cover 100 .

[0053] During installation, one end of the feeder 300 is first connected to the feeder 250, and then the beautifying cover 100 covers the antenna body 200, so that the other end of the feeder 300 is placed outside the beautifying cover 100. Afterwards, the antenna body 200 can be connected to the signal by simply connecting the feeder 300 to the external circuit, making the power connection process of the antenna body 200 more convenient.

[0054] In actual implementation, a hole, a groove or other structure for the feeding line 300 to pass through may be provided on the beautifying cover 100, and this is not limited.

[0055] like Figure 3 As shown, in some embodiments, the microstrip patch resonator 230 is provided with a first metal ground plate 231 , and the first metal ground plate 231 passes through the dielectric substrate 210 and is connected to the ground plate 220 .

[0056] Specifically, the first metal ground plate 231 can be made of copper, aluminum or other materials, and is disposed at the edge of the microstrip patch resonator 230 away from the substrate integrated waveguide resonator 240, and the first metal ground plate 231 is opposite to the substrate integrated waveguide resonator 240. The first metal ground plate 231 vertically penetrates the dielectric substrate 210, the upper end of the first metal ground plate 231 is connected to the microstrip patch resonator 230, and the lower end of the first metal ground plate 231 is connected to the floor 220.

[0057] Thus, the first metal ground plane 231 realizes the electric wall boundary condition, thereby reducing the size of the microstrip patch resonator 230 and halving the area; at the same time, the mechanical strength and stability of the entire microstrip patch resonator 230 structure are enhanced, and the performance changes caused by mechanical vibration or thermal expansion are reduced.

[0058] like Figure 3 As shown, in some embodiments, the substrate integrated waveguide resonator 240 is provided with a second metal ground plate 241 , the second metal ground plate 241 is connected to the floor 220 , and the second metal ground plate 241 is attached to the peripheral side of the dielectric substrate 210 .

[0059] Specifically, the second metal ground plate 241 can be made of copper, aluminum or other materials. The second metal ground plate 241 is arranged at the edge of the substrate integrated waveguide resonator 240 away from the microstrip patch resonator 230. The second metal ground plate 241 is vertically attached to the peripheral side of the dielectric substrate 210. The upper end of the second metal ground plate 241 is connected to the substrate integrated waveguide resonator 240, and the lower end of the second metal ground plate 241 is connected to the floor 220.

[0060] like Figure 3 As shown, further, the second metal ground plane 241 extends around at least two adjacent sides of the dielectric substrate 210, and the second metal ground plane 241 forms an open loop, and the microstrip patch resonator 230 is correspondingly arranged on one side of the opening of the open loop second metal ground plane 241. Thus, the size of the substrate integrated waveguide resonator 240 is halved.

[0061] In the embodiment of the present application, the second metal ground plate 241 extends around the sides of the dielectric substrate 210 in three adjacent directions, so that the microstrip patch resonator 230 corresponds to the side of the dielectric substrate 210 not covered by the second metal ground plate 241 .

[0062] Thus, by setting the second metal ground plate 241 as an open-loop structure, the coverage area of ​​the peripheral side of the dielectric substrate 210 is increased, that is, a reflection boundary of electromagnetic waves is provided for the substrate integrated waveguide resonator 240 from three different directions, thereby greatly reducing the loss of electromagnetic waves inside the substrate integrated waveguide resonator 240, and further optimizing the effect of electromagnetic wave coupling transmission to the microstrip patch resonator 230.

[0063] like Figure 3 As shown, in some embodiments, a gap 242 is formed on one side of the substrate integrated waveguide resonator 240 corresponding to the opening of the open-ring second metal ground plate 241 , and the microstrip patch resonator 230 is located in the gap 242 .

[0064] It should be noted that a region for avoiding the microstrip patch resonator 230 is provided on the substrate integrated waveguide resonator 240, and the region is the slot 242. In addition, the openings of the first metal ground plate 231 and the second metal ground plate 241 correspond to each other.

[0065] During installation, the microstrip patch resonator 230 only needs to be placed in the gap 242, and the spacing between the microstrip patch resonator 230 and the substrate integrated waveguide resonator 240 is relatively uniform. Thus, the space can be reasonably utilized without increasing the overall size of the antenna body 200, and the microstrip patch resonator 230 can be installed, thereby achieving the purpose of widening the bandwidth.

[0066] In other embodiments, the spacing between the microstrip patch resonator 230 and the substrate integrated waveguide resonator 240 can be changed from uniform to non-uniform, and the spacing between the microstrip patch resonator 230 and the substrate integrated waveguide resonator 240 can be adjusted to change the position of the radiation zero point according to actual needs.

[0067] like Figure 3 As shown, in some embodiments, the feeding element 250 includes a feeding probe, one end of which is connected to the substrate integrated waveguide resonator 240, and the feeding probe is located on the symmetry axis of the substrate integrated waveguide resonator 240, and the extension direction of the symmetry axis is consistent with the distribution direction of the microstrip patch resonator 230 and the substrate integrated waveguide resonator 240.

[0068] Among them, the feeding probe is set on the symmetry axis of the substrate integrated waveguide resonator 240. After the feeding probe is powered, it can ensure that the electromagnetic waves are evenly distributed in the substrate integrated waveguide resonator 240 and the microstrip patch resonator 230, thereby improving the performance of the substrate integrated waveguide resonator 240 and the microstrip patch resonator 230.

[0069] In other embodiments, the feeding element 250 may also be configured to include a microstrip feed line, and the microstrip feed line may be connected to the dielectric substrate 210 or the substrate integrated waveguide resonator 240 .

[0070] For example, Figure 4 As shown, the broadband characteristic is realized by two resonance points, namely, the half-mode TM in the microstrip patch resonator 230 10 and the TE in the substrate integrated waveguide resonator 240 11 . Figure 4In the figure, the dark and light lines represent the overall reflection coefficient of the antenna (S 11 ) and gain, the reflection coefficient reflects the working frequency band of the antenna. It can be seen that the working frequency band (S 11 There are two low points in the antenna (less than -10), which are generated by the resonant modes in the two resonators. The gain characterizes the radiation performance of the antenna. It can be seen that the gain is stable within the operating frequency band and there is a radiation zero point outside the high frequency band.

[0071] The area is 0.864λ g ×0.777λ g , the cross section is 0.059λ g Under the condition of -10dB bandwidth reaches 15%. In addition, a radiation zero point is generated outside the high frequency band of the passband, which greatly improves the out-of-band suppression level of the antenna body 200, thereby effectively reducing the mutual coupling effect with other antennas, thereby reducing the overall size of the antenna system.

[0072] like Figure 5 As shown, the maximum radiation direction of the antenna body 200 is perpendicular to the surface of the antenna body 200, and the cross polarization is low. Among them, the E plane refers to the plane where the electric field vector is located (i.e., the plane perpendicular to the floor 220), and the H plane refers to the plane where the magnetic field vector is located (i.e., the plane parallel to the floor 220); the main polarization refers to the main polarization direction, and the cross polarization refers to the polarization direction orthogonal to the main polarization.

[0073] like Figure 2 As shown, in some embodiments, the beautification cover 100 includes a cover body 110 and a fixing bracket 120 , the antenna body 200 is fixed to the mounting surface of the antenna body 200 through the fixing bracket 120 , the cover body 110 is connected to the fixing bracket 120 , and the cover body 110 covers the antenna body 200 .

[0074] Specifically, the fixing bracket 120 may be a plate-like structure, and of course, may be other shapes, which are not limited. The fixing bracket 120 may be fixed to the mounting surface of the antenna body 200 by screwing, clamping or other means. Subsequently, the antenna body 200 is fixed to the fixing bracket 120 by screwing or other means, and the cover body 110 is a one-side open structure. Finally, the cover body 110 covers the antenna body 200, and the cover body 110 is connected to the fixing bracket 120 by screwing, clamping or other means, thereby ensuring the stability of the cover body 110.

[0075] Thus, the cover 110 can provide protection for the antenna body 200, and the entire installation process is relatively convenient. Finally, a paint similar in color to the installation surface can be applied to the outside of the cover 110 to increase the concealment of the cover 110 and achieve the purpose of beautifying the antenna.

[0076] like Figure 2 and Figure 6 As shown, for fixing the antenna body 200 to the fixing bracket 120, it can be further configured as follows: the beautifying cover 100 also includes a connecting piece 130, the fixing bracket 120 is provided with a connecting portion 121, the antenna body 200 is detachably connected to the connecting piece 130, and the connecting piece 130 is detachably connected to the connecting portion 121.

[0077] It should be noted that the connecting member 130 may be configured to include two wing plates 131 , which are integrally formed and perpendicular to each other. Of course, the two wing plates 131 may also be connected by welding, which is not limited thereto.

[0078] The connecting portion 121 may be a plate-like structure, and the connecting portion 121 is perpendicular to the fixing bracket 120. The connecting portion 121 may also be other shapes, and there is no limitation on this. The connecting portion 121 may be fixed to the side of the fixing bracket 120 away from the mounting surface of the antenna body 200 by welding. Of course, the connecting portion 121 may also be integrally formed on the fixing bracket 120.

[0079] During installation, it is only necessary to fix the antenna body 200 on one of the wing plates 131 by screwing, bonding or other means, and then fix the other wing plate 131 on the connecting part 121 by screwing, snapping or other means, so as to fix the antenna body 200 on the fixing bracket 120. Therefore, the installation is relatively convenient and it is not easy to cause damage to the antenna body 200.

[0080] like Figure 2 As shown, in some embodiments, at least one supporting flange 122 is provided on the edge of the fixing bracket 120. When the cover body 110 covers the antenna body 200, each supporting flange 122 cooperates with the edge of the cover opening of the cover body 110 to limit the cover body 110 to the current position.

[0081] It can be understood that support flanges 122 can be set on the edges of the fixed bracket 120 in all directions, and the support flanges 122 are located on the side of the fixing bracket 120 away from the installation surface of the antenna body 200, and each support flange 122 is connected to each other, thereby forming a closed-loop structure of the support flange 122 as a whole on the edge of the fixing bracket 120, and the closed-loop structure of the support flange 122 as a whole is adapted to the cover opening of the cover body 110.

[0082] During installation, when the cover 110 covers the antenna body 200, the cover 110 can be matched with the supporting flange 122 as a whole, so as to pre-position the cover 110 and reduce the possibility of the cover 110 shifting, and then the cover 110 and the supporting flange 122 can be fastened with screws. In addition, when fastening the screws, there is no need to hold the cover 110 by hand, which improves the convenience of the fastening process of the cover 110.

[0083] In actual implementation, the overall diameter of the closed-loop support flange 122 can be smaller than / larger than the diameter of the cover opening of the cover body 110 , that is, the cover body 110 can be arranged on the inner side or the outer side of the support flange 122 .

[0084] In other embodiments, the support flanges 122 may be provided on only two opposite edges of the fixing bracket 120 , or on three edges or one edge, and there is no limitation to this.

[0085] In summary, the embodiment of the present application provides a miniaturized beautification antenna. When working, the external signal is coupled to the substrate integrated waveguide resonator 240 through the feeder 250. The substrate integrated waveguide resonator 240 generates a strong electromagnetic wave at the resonant frequency, and then the electromagnetic wave is coupled and transmitted to the microstrip patch resonator 230 to excite the microstrip patch resonator 230 to resonate, thereby realizing a dual-mode resonance characteristic, so that the bandwidth is effectively widened, so that the space can be effectively utilized, and the bandwidth is widened without increasing the overall size of the antenna. The antenna structure is more compact and has a low profile, and the size of the required beautification cover 100 is reduced, and the beautification antenna effect is optimized. In addition, the electric and magnetic hybrid coupling between the microstrip patch resonator 230 and the substrate integrated waveguide resonator 240 will produce a radiation zero point, thereby achieving filtering performance. Therefore, the problem that the antenna in the prior art has a high profile when meeting the requirements of a wide bandwidth, which makes the use effect of the beautification antenna poor is solved.
