Description

Technical Field

[0001] This invention relates to the field of signal equipment technology, and more specifically to a transparent antenna device. Background Technology

[0002] With the continuous development of display signal equipment technology, the shape of signal equipment is becoming increasingly easier to integrate with building facades. Taking antennas as an example, to enhance their aesthetic appeal, antennas are often designed with biomimetic structures to beautify their appearance. However, when antennas are mounted on building facades, limitations in the antenna's structure and materials often cause them to protrude, failing to match the shape and color of the building's exterior. This affects the uniformity of the building's surface and increases the risk of antenna damage. Summary of the Invention

Furthermore, since the shielding plate covers the first position of the first sidewall of the encapsulation shell—the first position being the location of the connection between the parasitic radiation component, reflective component, and main radiation component within the encapsulation shell—the shielding plate can cover the connection between the parasitic radiation component, reflective component, and main radiation component, thus hiding the internal structure of the transparent antenna. This ensures the cleanliness of the transparent portion of the antenna while preventing it from protruding from the building's exterior wall in terms of shape and structure, thereby reducing the risk of antenna damage.

Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0051] This invention provides a transparent antenna device. Figure 1 This is an exploded structural diagram of the transparent antenna device provided in an embodiment of the present invention. Figure 2 This diagram illustrates another exploded view of the transparent antenna device provided in this embodiment of the invention. Figure 3 This diagram illustrates the external structure of the transparent antenna device provided in one direction according to an embodiment of the present invention. Figure 4 This diagram illustrates the external structure of the transparent antenna device provided in an embodiment of the present invention in another direction, as shown below. Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, the transparent antenna device includes a housing 1, a supporting frame 2, a parasitic radiation component 3, a main radiation component 4, and a reflective component 5. The parasitic radiation component 3 includes an antenna radome 31 and a parasitic radiation antenna 32, with the parasitic radiation antenna 32 fixed to the surface of the antenna radome 31. The main radiation component 4 is fixed between the reflective component 5 and the antenna radome 31. The housing 1 is a housing with an open top, and the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 are installed in the inner cavity of the housing 1. The supporting frame 2 includes a shielding plate 21, which covers a first position on the first sidewall of the housing 1. The first sidewall is a sidewall in the housing 1 that is parallel to the surface of the antenna radome 31. The first position is the location of the connection between the parasitic radiation component 3, the reflective component 5, and the main radiation component 4 in the housing 1. The housing 1, the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 are all transparent structures, while the shielding plate 21 is a non-transparent structure.

[0052] The parasitic radiation component 3 is the main component in the transparent antenna device that radiates and receives radio waves. The parasitic radiation component 3 includes an radome 31 and a parasitic radiation antenna 32, which is fixed to the surface of the radome 31. The parasitic radiation antenna 32 is a sheet-like biomimetic antenna. In this embodiment, to ensure a large radiation and reception area, the parasitic radiation antenna 32 can be a U-shaped sheet structure, positioned around the edge of the radome 31 during installation. The radome 31 is a plate-like component that fixes and limits the parasitic radiation antenna 32. The radome 31 can be a square plate-like component, a circular plate-like component, or a plate-like component of other shapes; this embodiment does not limit the shape.

[0053] Optional, such as Figure 6 As shown, the radome 31 may include a baffle 311 and a cover plate 312; the baffle 311 is disposed at the end of the cover plate 312, and the plane on which the baffle 311 is located is perpendicular to the plane on which the cover plate 312 is located, and the end of the baffle 311 faces the main radiating component 4; the parasitic radiating antenna 32 is bonded to the cover surface of the cover plate 312, and the surface of the cover plate 312 opposite to the cover surface is in contact with the inner wall of the encapsulation housing 1.

[0054] It should be noted that the radome 31, including the baffle 311 and the cover plate 312, can form an L-shaped plate structure. The cover plate 312 provides a fixed space for the parasitic radiating antenna 32. Since the plane of the baffle 311 is perpendicular to the plane of the cover plate 312, the baffle 311 can limit the parasitic radiating antenna 32 when it is bonded to the cover surface of the cover plate 312. While protecting the structure of the parasitic radiating antenna 32, the baffle 311, with its end facing the main radiating component 4, can maintain a certain distance between the parasitic radiating antenna 32 and the vibrator 42, which is beneficial to ensuring the performance of the transparent antenna device. In addition, the surface of the cover plate 312 opposite to the cover surface is in contact with the inner wall of the encapsulation housing 1, that is, the outer surface of the cover plate 312 is pressed against the surface of the inner wall of the encapsulation housing 1, thereby ensuring that the surface of the radome 31 can maintain a certain flatness.

[0055] Furthermore, the main radiating component 4 is fixed between the reflecting component 5 and the radome 31. The main radiating component 4 is a device that enhances the radiated signal of the parasitic radiating antenna 32. The reflecting component 5 is a device that concentrates and reflects the electromagnetic waves generated by the radiated signal in the antenna in a preset direction. In this embodiment of the invention, after the parasitic radiating component 3, the main radiating component 4, and the reflecting component 5 are assembled into a whole, they are installed as a whole into the inner cavity of the encapsulation housing 1, which facilitates the installation of the parasitic radiating component 3, the main radiating component 4, and the reflecting component 5.

[0056] It should be noted that the encapsulation housing 1 is an open-top housing. The encapsulation housing 1 can be a single, square housing structure, or it can be formed by sealing two housings together through potting. In one possible implementation, the encapsulation housing 1 includes an outer shell 11 and a bottom cover 12. The outer shell 11 is a bottom-opening housing, and the bottom cover 12 is fixed to the opening at the bottom of the outer shell 11. One end of the parasitic radiation component 3, one end of the main radiation component 4, and one end of the reflective component 5 press against the protruding rib 124 of the bottom cover 12. The outer shell 11 and the bottom cover 12 can be sealed by potting to ensure the sealing performance of the inner cavity of the encapsulation housing 11. In this embodiment of the invention, the overall structure formed by the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 can be inserted from the opening at the bottom of the housing 11, and then the bottom cover 12 can be sealed on, so that the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 press against the protruding ribs 124 of the bottom cover of the housing 1, so that the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 are supported by the protruding ribs 124, and the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 are limited by the protruding ribs 124 in the sliding direction.

[0057] Furthermore, to prevent water accumulation in the bottom cover 12, such as Figure 9As shown, a waterproof and breathable hole 122 can be opened at the bottom of the bottom cover 12, and a waterproof and breathable membrane 123 is attached thereon. In this way, the waterproof and breathable hole 122 can ensure that water droplets generated by external rain cannot drip onto the waterproof and breathable membrane 123, and the waterproof and breathable membrane 123 can minimize direct contact with external water droplets, ensuring that the parasitic radiation component 3, the main radiation component 4 and the reflective component 5 in contact with the bottom cover remain dry.

[0058] It should also be noted that the encapsulation housing 1, parasitic radiation component 3, main radiation component 4, and reflective component 5 are all transparent structures, including but not limited to any material such as polymethyl methacrylate, polystyrene, polycarbonate, styrene-acrylonitrile, and styrene-methyl methacrylate copolymer. This application embodiment does not limit the specific materials used. Thus, when the transparent antenna device is externally mounted on a building's exterior wall, the transparent antenna will not protrude from the wall, allowing it to blend seamlessly with the building's color, maintaining the uniformity of the exterior surface, and reducing the risk of antenna damage.

[0059] Furthermore, in this embodiment of the invention, to ensure the overall transparency of the transparent antenna structure by concealing the connection points of the parasitic radiating component 3, the reflecting component 5, and the main radiating component 4 within the encapsulation housing 1, the parasitic radiating antenna 32 device also includes a supporting outer frame 2. The supporting outer frame 2 includes a shielding plate 21, which is a strip-shaped structure. The length of the shielding plate 21 is the same as the length of the outer surface of the encapsulation housing 11, and the width of the shielding plate 21 is determined based on the dimensions of the connection points of the parasitic radiating component 3, the reflecting component 5, and the main radiating component 4. The shielding plate 21 is fixed at a first position on the first sidewall of the encapsulation housing 1. Since the first position is the location of the connection points of the parasitic radiating component 3, the reflecting component 5, and the main radiating component 4 within the encapsulation housing 1, the shielding plate 21 can block these connection points, thereby ensuring the cleanliness of the transparent portion of the transparent antenna and further concealing the internal structure of the transparent antenna. It should be noted that the shielding plate 21 can be located on the surface of the encapsulation housing 1 or between the encapsulation housing 1 and the building's exterior wall; this embodiment of the invention does not limit this.

[0060] As can be seen from the above embodiments, in this embodiment of the invention, since the transparent antenna device includes an encapsulation housing 1, a supporting outer frame 2, and the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 are all transparent structures, when the transparent antenna device is hung on the exterior wall of a building, it can match the color of the exterior wall and will not affect the consistency of the exterior wall surface. Furthermore, since the shielding plate 21 covers the first position of the first sidewall of the encapsulation housing 1, and the first position is the location of the connection between the parasitic radiation component 3, the reflective component 5, and the main radiation component 4 within the encapsulation housing 1, the shielding plate 21 can cover the connection between the parasitic radiation component 3, the reflective component 5, and the main radiation component 4, thus hiding the internal structure of the transparent antenna. This ensures the cleanliness of the transparent part of the transparent antenna while preventing the transparent antenna from protruding from the exterior wall in terms of shape and structure, thereby reducing the risk of antenna damage.

[0061] In some embodiments, such as Figure 7 As shown, the main radiating assembly 4 includes a main radiating liner 41 and an element 42; the element 42 is bonded to a second position on the first surface of the main radiating liner 41, the main radiating liner 41 and the cover plate 312 are inserted together, the cover surface of the cover plate 312 covers the first surface of the main radiating liner 41, and the parasitic radiating antenna 32 is arranged around the element 42; the main radiating liner 41 is inserted into the reflecting assembly 5, the second surface of the main radiating liner 41 covers the reflecting assembly 5, and the first surface and the second surface are two opposite surfaces of the main radiating liner 41.

[0062] It should be noted that the main radiating plate 41 is also a transparent plate structure. The area of ​​the main radiating plate 41 is equal to that of the cover plate 312. The main radiating plate 41 provides sufficient installation space for the vibrator 42 and prevents the vibrator 42 from deforming. Since the cover plate 312 covers the first surface of the main radiating plate 41, and the parasitic radiating antenna 32 is arranged around the vibrator 42, the parasitic radiating antenna 32 can guide and amplify electromagnetic waves through the vibrator 42, making the electromagnetic signal received by the parasitic radiating antenna 32 stronger.

[0063] It should also be noted that, such as Figure 6 and Figure 7As shown, the cover plate 312 and the main radiating liner 41 are fixed as follows: Multiple protrusions 3121 are provided on the end of the cover plate 312 opposite to the baffle 311; the protrusions 3121 protrude towards the main radiating assembly 4; a connecting shaft 3122 is provided at the top of one or more of the protrusions 3121; a connecting hole 411 is provided on the second surface of the main radiating liner 41, and the connecting shaft 3122 is inserted into the connecting hole 411. In this way, the cover plate 312 and the main radiating liner 41 are connected and positioned through the shaft, ensuring that the cover plate 312 and the main radiating liner 41 maintain a stable position in a direction perpendicular to the first surface of the main radiating liner 41.

[0064] Furthermore, a limiting plate 412 is also provided on the second surface of the main radiating plate 41; the end of the limiting plate 412 faces the reflector 5, and when the main radiating plate 41 and the reflector 5 are inserted, the end of the limiting plate 412 presses against the surface of the reflector 5. In this way, under the action of the limiting plate 412, a certain distance is maintained between the reference ground layer 52 included in the reflector 5 and the vibrator 42, which is beneficial to ensuring the performance of the transparent antenna device.

[0065] It should be noted that, as Figure 7 and Figure 8 As shown, the reflector 5 and the main radiating component 4 are fixed as follows: the reflector 5 includes a reflector plate 51 and a reference ground layer 52; the third surface of the reference ground layer 52 is bonded to the surface of the reflector plate 51, and a mounting through hole 521 is formed on the fourth surface of the reference ground layer 52; a mounting boss 413 is provided on the second surface of the main radiating plate 41, and the mounting boss 413 is engaged in the mounting through hole 521. The third and fourth surfaces are two opposing surfaces of the reference ground layer 52. In this way, the reflector 5 and the main radiating component 4 are connected by the mounting boss 413 and the mounting through hole 521, so that the reflector 5 and the main radiating component 4 can maintain a stable position in the direction perpendicular to the first surface of the main radiating plate 41.

[0066] Optionally, the transparent antenna device also includes a feed line circuit board 6, and the reflector liner 51 includes a reflector 522 and a mounting plate 523; the mounting plate 523 is located at the end of the reflector 522, and the plane of the mounting plate 523 intersects the plane of the reflector 522, and the feed line circuit board 6 is mounted on the mounting plate 523.

[0067] It should be noted that the feeder circuit board 6 is the circuit board that supplies power to the vibrator 42. The pads of the feeder circuit board 6 can be soldered to the corresponding solder points of the vibrator 42 and the corresponding solder points of one end of the coaxial cable of the RF cable to achieve electrical connection. In this way, by connecting the feeder circuit board 6 to the mounting plate 523 included in the reflector liner 51, since the plane on which the mounting plate 523 is located intersects with the plane on which the reflector liner 522 is located, the installation of the feeder circuit board 6 will not affect the reflection of electromagnetic signals by the reflector liner 51.

[0068] To facilitate the installation of the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 within the encapsulation housing 1, such as Figure 5 As shown, the inner wall of the outer casing 11 is provided with a first sliding groove 111, a second sliding groove 112 and a third sliding groove 113; the first sliding groove 111, the second sliding groove 112 and the third sliding groove 113 are all opened along the extension direction of the inner cavity of the outer casing 11, and the second sliding groove 112 is located between the first sliding groove 111 and the third sliding groove 113; the parasitic radiation component 3, the main radiation component 4 and the reflective component 5 slide into the inner cavity of the outer casing 11 through the first sliding groove 111, the second sliding groove 112 and the third sliding groove 113. In this way, when the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 are installed in the inner cavity of the encapsulation housing 1, the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 can be slid into the encapsulation housing 1 from the top opening through the first slide groove 111, the second slide groove 112, and the third slide groove 113. While facilitating the installation of the parasitic radiation component 3, the main radiation component 4, and the reflective component 5, the first slide groove 111, the second slide groove 112, and the third slide groove 113 can also hold the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 in place, so that the positions of the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 in the extending directions of the first slide groove 111, the second slide groove 112, and the third slide groove 113 remain fixed.

[0069] It should be noted that, as Figure 5 and Figure 9 As shown, the outer shell 11 and the bottom cover 12 are fixed as follows: An embedded stud 114 is provided on the outer wall of the outer shell 11, and a fixing screw 121 is provided on the inner wall of the bottom cover 12. The embedded stud 114 is located on the two second side walls of the outer shell 11 near the outer wall of the bottom cover, and the fixing screw 121 is screwed onto the embedded stud 114. The second side walls are the side walls of the outer shell 11 that intersect with the radome 31. In this way, while the outer shell 11 and the bottom cover are fixed by the fixing screw 121 and the embedded stud 114, the shell and bottom cover are detachably connected, facilitating the later assembly and adjustment of the internal structure of the transparent antenna.

[0070] To increase the overall rigidity of the transparent antenna device, in this embodiment of the invention, the supporting frame 2 further includes a first support piece 22 and a second support piece 23. The first support piece 22 and the second support piece 23 are respectively fixed to the ends of the shielding piece 21, and the planes where the first support piece 22 and the second support piece 23 are located intersect with the plane where the shielding piece 21 is located. The first support piece 22 and the second support piece 23 are respectively fixed to two second sidewalls. In this way, the first support piece 22 and the second support piece 23 can increase the overall rigidity of the transparent antenna device, avoiding unnecessary damage to the transparent encapsulation shell 1, parasitic radiation component 3, main radiation component 4, and reflection component 5 during the assembly and adjustment of the transparent antenna.

[0071] To facilitate the connection between the transparent antenna and the building's exterior wall, the transparent antenna device also includes a connecting frame 7; the connecting frame 7 includes a first connecting plate 71 and a second connecting plate 72, the first connecting plate 71 is fixed on the first support plate 22, and the second connecting plate 72 is fixed on the second support plate 23.

[0072] Furthermore, the first connecting plate 71 and the second connecting plate 72 are respectively provided with a first arc-shaped sliding groove and a second arc-shaped sliding groove; the first connecting plate 71 is detachably connected to the first support piece 22 through the first arc-shaped sliding groove, and the second connecting plate 72 is detachably connected to the second support piece 23 through the second arc-shaped sliding groove. It should be noted that both the first connecting plate 71 and the second connecting plate 72 can be L-shaped plates. Threaded holes can be opened on one surface of the L-shaped plate to facilitate assembly with the building exterior wall. An arc-shaped sliding groove with graduations can be opened on the other surface of the L-shaped plate to facilitate assembly with the supporting outer frame 2. When the connection position of the first connecting plate 71 and the first support piece 22 in the first arc-shaped sliding groove changes, and the connection position of the second connecting plate 72 and the second support piece 23 in the second arc-shaped sliding groove changes, the installation angle between the transparent antenna device and the building exterior wall also changes, making it easier to adjust the installation angle between the transparent antenna device and the building exterior wall.

[0073] As can be seen from the above embodiments, in this embodiment of the invention, since the transparent antenna device includes an encapsulation housing 1, a supporting outer frame 2, and the parasitic radiation component 3, the main radiation component 4, and the reflective component 5 are all transparent structures, when the transparent antenna device is hung on the exterior wall of a building, it can match the color of the exterior wall and will not affect the consistency of the exterior wall surface. Furthermore, since the shielding plate 21 covers the first position of the first sidewall of the encapsulation housing 1, and the first position is the location of the connection between the parasitic radiation component 3, the reflective component 5, and the main radiation component 4 within the encapsulation housing 1, the shielding plate 21 can cover the connection between the parasitic radiation component 3, the reflective component 5, and the main radiation component 4, thus hiding the internal structure of the transparent antenna. This ensures the cleanliness of the transparent part of the transparent antenna while preventing the transparent antenna from protruding from the exterior wall in terms of shape and structure, thereby reducing the risk of antenna damage.
