Abstract

The invention provides a high-gain millimeter wave antenna structure and a millimeter wave antenna module thereof. The high-gain millimeter wave antenna structure comprises a first reflecting plate, a second reflecting plate and a millimeter wave antenna module. The first reflecting plate is provided with a first concave area and a first focusing area. The second reflecting plate is provided with a second concave area and a second focusing area. The millimeter wave antenna module is arranged between the first reflecting plate and the second reflecting plate. When the millimeter wave antenna module is configured to selectively provide an original millimeter wave signal, the original millimeter wave signal provided by the millimeter wave antenna module is sequentially reflected by the first reflecting plate and the second reflecting plate to form a working millimeter wave signal transmitted towards the same preset direction. Therefore, a working antenna gain of a working millimeter wave signal provided by mutual cooperation of the millimeter wave antenna module, the first reflecting plate and the second reflecting plate can be greater than an original antenna gain of an original millimeter wave signal provided by the millimeter wave antenna module.

Description

Technical Field

[0001] This invention relates to an antenna structure and its antenna module, and more particularly to a high-gain millimeter-wave antenna structure and its millimeter-wave antenna module. Background Technology

[0002] In existing technologies, millimeter-wave antenna modules employ a large or even massive array of antennas. When a large or massive array of antennas forms a beam, the half-power beamwidth narrows as the number of antenna elements in the array increases. Millimeter-wave frequencies offer ample bandwidth, which can be used to compensate for transmission losses in outdoor high-frequency communications and can also achieve high transmission rates. However, existing millimeter-wave antenna modules still have room for improvement. Summary of the Invention

[0003] The problem this invention aims to improve or solve is to provide a high-gain millimeter-wave antenna structure and its millimeter-wave antenna module, addressing the shortcomings of existing technologies. When the millimeter-wave antenna module is configured to selectively provide a raw millimeter-wave signal, the raw millimeter-wave signal provided by the millimeter-wave antenna module can be reflected sequentially by a first reflector and a second reflector to form a working millimeter-wave signal transmitted in the same predetermined direction.

[0004] To improve or solve the above-mentioned problems, one of the technical means adopted by the present invention is to provide a high-gain millimeter-wave antenna structure, which includes: a first reflector, a second reflector, and a millimeter-wave antenna module. The first reflector has a first recessed region. The second reflector has a second recessed region. The millimeter-wave antenna module is disposed between the first reflector and the second reflector. The first reflector and the second reflector are correspondingly arranged, with the first recessed area of ​​the first reflector being smaller than the second recessed area of ​​the second reflector, and the first recessed area of ​​the first reflector facing the second recessed area of ​​the second reflector. The first reflector has a first focusing area, and the millimeter-wave antenna module is disposed within the first focusing area of ​​the first reflector. The second reflector has a second focusing area, and the first reflector is disposed within the second focusing area of ​​the second reflector. When the millimeter-wave antenna module is configured to selectively provide a raw millimeter-wave signal, the raw millimeter-wave signal provided by the millimeter-wave antenna module is reflected sequentially by the first reflector and the second reflector to form a working millimeter-wave signal transmitted in the same predetermined direction. The working antenna gain of the working millimeter-wave signal provided by the cooperation of the millimeter-wave antenna module, the first reflector, and the second reflector is greater than the original antenna gain of the raw millimeter-wave signal provided by the millimeter-wave antenna module.

[0005] To improve or solve the above-mentioned problems, another technical means adopted by the present invention is to provide a high-gain millimeter-wave antenna structure, which includes: a first reflector, a second reflector, and a millimeter-wave antenna module. The first reflector has a first recessed region. The second reflector has a second recessed region. The millimeter-wave antenna module is disposed between the first reflector and the second reflector. The first reflector and the second reflector are correspondingly disposed, the first recessed region of the first reflector is smaller than the second recessed region of the second reflector, and the first recessed region of the first reflector faces the second recessed region of the second reflector; the first reflector has a first focusing region, and the second reflector has a second focusing region; the working antenna gain of a working millimeter-wave signal provided by the cooperation of the millimeter-wave antenna module, the first reflector, and the second reflector is greater than the original antenna gain of the original millimeter-wave signal provided by the millimeter-wave antenna module.

[0006] To improve or solve the above-mentioned problems, another technical means adopted by the present invention is to provide a millimeter-wave antenna module, which includes: a millimeter-wave antenna and at least one focusing lens, wherein the millimeter-wave antenna is disposed within the focusing area of ​​a first lens of the at least one focusing lens.

[0007] One of the beneficial effects of this invention is that the high-gain millimeter-wave antenna structure provided by this invention, through the technical solutions of "the millimeter-wave antenna module being disposed between the first reflector and the second reflector", "the first recessed area of ​​the first reflector being smaller than the second recessed area of ​​the second reflector", "the first recessed area of ​​the first reflector facing the second recessed area of ​​the second reflector", "the first reflector having a first focusing area", and "the second reflector having a second focusing area", enables the millimeter-wave antenna module to be configured to selectively provide a raw millimeter-wave signal. The raw millimeter-wave signal provided by the millimeter-wave antenna module is reflected sequentially by the first reflector and the second reflector to form a working millimeter-wave signal transmitted in the same predetermined direction. It is worth noting that the working antenna gain of the working millimeter-wave signal provided by the cooperation of the millimeter-wave antenna module, the first reflector, and the second reflector can be greater than the original antenna gain of the raw millimeter-wave signal provided by the millimeter-wave antenna module.

[0008] One beneficial effect of this invention is that the millimeter-wave antenna module provided by this invention, through the technical solution of "the millimeter-wave antenna module including a millimeter-wave antenna and at least one focusing lens" and "the millimeter-wave antenna being disposed within the focusing area of ​​a first lens of the at least one focusing lens," allows the original millimeter-wave signal provided by the millimeter-wave antenna of the millimeter-wave antenna module to pass through at least one focusing lens when the millimeter-wave antenna of the millimeter-wave antenna module is configured to selectively provide an original millimeter-wave signal. Therefore, the original millimeter-wave signal provided by the millimeter-wave antenna module through the cooperation of the millimeter-wave antenna and at least one focusing lens can be reflected sequentially by a first reflector and a second reflector to form a working millimeter-wave signal transmitted in the same predetermined direction. It is worth noting that the working antenna gain of the working millimeter-wave signal provided by the cooperation of the millimeter-wave antenna module, the first reflector, and the second reflector can be greater than the original antenna gain of the original millimeter-wave signal provided by the millimeter-wave antenna module.

Those skilled in the art can understand the advantages and effects of this invention from the content disclosed in this specification.

Furthermore, it should be stated in advance that the accompanying drawings of this invention are for simple illustration only and are not depictions based on actual dimensions. The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention. In addition, the term "or" used herein may, depending on the actual situation, include any combination of any one or more of the associated listed items.

[0019] First Embodiment

[0020] See Figures 1 to 4 As shown, the first embodiment of the present invention provides a high-gain millimeter-wave antenna structure M, which may include: a first reflector 1 (or a first antenna signal reflector), a second reflector 2 (or a second antenna signal reflector), and a millimeter-wave antenna module 3. More specifically, the first reflector 1 may have a first recessed region 100 (or a first concave region), the second reflector 2 may have a second recessed region 200 (or a second concave region), and the millimeter-wave antenna module 3 is disposed between the first reflector 1 and the second reflector 2. Furthermore, the first reflector 1 and the second reflector 2 may be correspondingly arranged, the first recessed region 100 of the first reflector 1 may be smaller than the second recessed region 200 of the second reflector 2, and the first recessed region 100 of the first reflector 1 may face the second recessed region 200 of the second reflector 2.

[0021] For example, coordination Figure 1 and Figure 3As shown, the first reflector 1 may have a first focusing area, and depending on different requirements, the millimeter-wave antenna module 3 may be "set within the range of the first focusing area of ​​the first reflector 1 (that is, the first focusing area is not just a single point, but a range that can cover a predetermined space)" or "adjacent to the range of the first focusing area of ​​the first reflector 1" (that is, the millimeter-wave antenna module 3 may be completely or partially set within the range of the first focusing area of ​​the first reflector 1, or the millimeter-wave antenna module 3 may not be set within the range of the first focusing area of ​​the first reflector 1 at all). Additionally, the second reflector 2 may have a second focusing area, and depending on different requirements, the first reflector 1 may be "set within the range of the second focusing area of ​​the second reflector 2 (that is, the second focusing area is not just a single point, but a range that can cover a predetermined space)" or "adjacent to the range of the second focusing area of ​​the second reflector 2" (that is, the second reflector 2 may be completely or partially set within the range of the second focusing area of ​​the second reflector 2, or the second reflector 2 may not be set within the range of the second focusing area of ​​the second reflector 2 at all). However, the examples given above are merely one possible embodiment and are not intended to limit the present invention.

[0022] For example, coordination Figure 1 , Figure 2 and Figure 3As shown, the first recessed region 100 of the first reflector 1 may have a protruding tip 1001 (or a central protruding portion) and a first signal reflecting surface 1002 (or a first surrounding reflective surface) surrounding the protruding tip 1001. Additionally, the second reflector 2 may have a through opening 2001 (e.g., circular, polygonal, or arbitrary shape) communicating with the second recessed region 200, and the second recessed region 200 of the second reflector 2 may have a second signal reflecting surface 2002 (or a second surrounding reflective surface) surrounding the through opening 2001. It is noteworthy that the first signal reflecting surface 1002 of the first recessed region 100 of the first reflector 1 may have a first focusing region, and the second signal reflecting surface 2002 of the second recessed region 200 of the second reflector 2 may have a second focusing region. Furthermore, the first reflector 1 may have a first diameter D1 between 10 mm and 40 mm (e.g., any positive integer between 10 mm and 40 mm) and a first height H1 between 20 mm and 80 mm (e.g., any positive integer between 20 mm and 80 mm), and the second reflector 2 may have a second diameter D2 between 100 mm and 200 mm (e.g., any positive integer between 100 mm and 200 mm) and a second height H2 between 20 mm and 80 mm (e.g., any positive integer between 20 mm and 80 mm). Additionally, the first reflector 1 and the second reflector 2 can be supported or positioned by any support structure or load-bearing structure. However, the examples given above are merely one possible embodiment and are not intended to limit the invention.

[0023] For example, coordination Figure 1 and Figure 3As shown, the millimeter-wave antenna module 3 can be configured as an antenna array module 31. The antenna array module 31 may include multiple microstrip patch antenna elements 300 or multiple microstrip patch antennas arranged in a predetermined array shape (e.g., a 4x4 array, or an array of any sequence). Depending on the requirements, the antenna array module 31 may be "located within the first focusing area of ​​the first reflector 1" or "adjacent to the first focusing area of ​​the first reflector 1." It is worth noting that the millimeter-wave antenna module 3 can be located outside the second recessed area 200 of the second reflector 2 (that is, the millimeter-wave antenna module 3 is not surrounded by the second reflector 2 at all). The millimeter-wave antenna module 3 can be positioned between the first reflector 1 and the second reflector 2 by being supported by an antenna support structure 4 (or an antenna carrier structure, which may use a low dielectric constant material and reduce its volume to reduce the problem of multiple reflections or diffraction of the signal). In one feasible embodiment, depending on the requirements, the millimeter-wave antenna module 3 may also be "mounted at the bottom of the second reflector 2" or "mounted at a position beyond the bottom of the second reflector 2." Furthermore, the antenna support structure 4 can pass through the through-hole 2001 of the second reflector 2 to guide (or not guide) an electrical connection to the coaxial cable 5 (or an antenna signal transmission line) of the millimeter-wave antenna module 3. The millimeter-wave antenna module 3 can also be electrically connected to a circuit board (not shown) or an electronic chip (not shown) via the coaxial cable 5. Further, the second diameter D2 of the second reflector 2 can be greater than or equal to the first diameter D1 of the first reflector 1, the first diameter D1 of the first reflector 1 can be greater than or equal to a maximum width W (or a maximum length) of the millimeter-wave antenna module 3, and the maximum width W of the millimeter-wave antenna module 3 can be greater than, equal to, or less than the opening diameter D3 of the through-hole 2001 of the second reflector 2. However, the examples given above are merely one possible embodiment and are not intended to limit the invention.

[0024] In this way, to cooperate Figure 3 and Figure 4As shown, when the millimeter-wave antenna module 3 (e.g., an antenna array module 31 that may include multiple microstrip patch antenna elements 300) is configured to selectively provide a raw millimeter-wave signal S1 (or an initial radio frequency wave, or an initial antenna beam), the raw millimeter-wave signal S1 provided by the millimeter-wave antenna module 3 can be reflected sequentially by the first reflector 1 and the second reflector 2 to form a working millimeter-wave signal S2 (or a working radio frequency wave, or a working antenna beam) transmitted in the same predetermined direction. It is worth noting that the working antenna gain (or an adjusted antenna gain) of the working millimeter-wave signal S2 provided by the cooperation of the millimeter-wave antenna module 3, the first reflector 1, and the second reflector 2 can be greater than the original antenna gain (or the unadjusted antenna gain) of the raw millimeter-wave signal S1 provided by the millimeter-wave antenna module 3. In other words, when the antenna array module 31 of the millimeter-wave antenna module 3 can be configured to selectively provide the original millimeter-wave signal S1, the original millimeter-wave signal S1 provided by the antenna array module 31 can be reflected sequentially by the first signal reflecting surface 1002 of the first reflector 1 and the second signal reflecting surface 2002 of the second reflector 2 to form a working millimeter-wave signal S2 transmitted in the same predetermined direction. For example, the wavelength of the original millimeter-wave signal S1 can be between 1 mm and 10 mm (e.g., any positive integer between 1 mm and 10 mm), and the frequency of the original millimeter-wave signal S1 can be between 28 GHz and 300 GHz (e.g., any positive integer between 28 GHz and 300 GHz). In one feasible embodiment, when the frequency of the original millimeter-wave signal S1 is set to approximately 28 GHz, the original antenna gain of the original millimeter-wave signal S1 provided by the millimeter-wave antenna module 3 (e.g., using multiple microstrip patch antenna elements 300) can reach approximately 16 dBi, and the working antenna gain of the working millimeter-wave signal S2 provided by the cooperation of the millimeter-wave antenna module 3, the first reflector 1, and the second reflector 2 can reach approximately 24 dBi. However, the examples given above are merely feasible embodiments and are not intended to limit the present invention.

[0025] Second Embodiment

[0026] See Figures 5 to 8 As shown, the second embodiment of the present invention provides a high-gain millimeter-wave antenna structure M, which may include: a first reflector 1, a second reflector 2, and a millimeter-wave antenna module 3. Figures 5 to 8 respectively with Figures 1 to 4A comparison reveals that the most significant difference between the second embodiment and the first embodiment of the present invention lies in the following: In the second embodiment, the millimeter-wave antenna module 3 may include a millimeter-wave antenna 32 and at least one focusing lens 33, and the millimeter-wave antenna 32 may include at least one microstrip patch antenna element 300 or a single microstrip patch antenna. Furthermore, the millimeter-wave antenna 32 may be disposed between at least one focusing lens 33 and the second reflector 2, and the at least one focusing lens 33 may be disposed between the millimeter-wave antenna 32 and the first reflector 1.

[0027] For example, depending on different requirements, the millimeter-wave antenna 32 can be "set within the focusing area of ​​a first lens of at least one focusing lens 33 (that is, the focusing area of ​​the first lens is not a single point, but a range that can cover a predetermined space)" or "adjacent to the focusing area of ​​the first lens of at least one focusing lens 33" (that is, the millimeter-wave antenna 32 can be completely or partially set within the focusing area of ​​the first lens of at least one focusing lens 33, or the millimeter-wave antenna 32 can be completely excluded from the focusing area of ​​the first lens of at least one focusing lens 33). Similarly, depending on different requirements, the first reflector 1 can be "set within the focusing area of ​​a second lens of at least one focusing lens 33 (that is, the focusing area of ​​the second lens is not a single point, but a range that can cover a predetermined space)" or "adjacent to the focusing area of ​​the second lens of at least one focusing lens 33" (that is, the first reflector 1 can be completely or partially set within the focusing area of ​​the second lens of at least one focusing lens 33, or the first reflector 1 can be completely excluded from the focusing area of ​​the second lens of at least one focusing lens 33). It is worth noting that at least one focusing lens 33 (or at least one high dielectric constant lens) can be configured as a ceramic focusing lens, a mica focusing lens, a glass focusing lens, a plastic focusing lens, or any type of high dielectric constant lens. Furthermore, the use of at least one focusing lens 33 with a high dielectric constant provides advantages such as thinness, small temperature coefficient variation, small air gap (low porosity), stable dielectric constant, resistance to breakage, and high gain. Additionally, the second diameter D2 of the second reflector 2 can be greater than or equal to the lens diameter D4 of the at least one focusing lens 33, the lens diameter D4 of the at least one focusing lens 33 is greater than or equal to the first diameter D1 of the first reflector 1, and the at least one focusing lens 33 can have a thickness between 1000 μm and 3000 μm (e.g., any positive integer between 1000 μm and 3000 μm). Moreover, the first reflector 1, the second reflector 2, and the at least one focusing lens 33 can be supported or positioned by any support structure or load-bearing structure. However, the examples given above are merely one possible embodiment and are not intended to limit the invention.

[0028] In this way, to cooperate Figure 7 and Figure 8As shown, when the millimeter-wave antenna module 3 (e.g., an antenna array module 31 that may include a millimeter-wave antenna 32 and at least one focusing lens 33) is configured to selectively provide a raw millimeter-wave signal S1 (or an initial radio frequency wave, or an initial antenna beam), the raw millimeter-wave signal S1 provided by the millimeter-wave antenna module 3 can be reflected sequentially by the first reflector 1 and the second reflector 2 to form a working millimeter-wave signal S2 (or a working radio frequency wave, or a working antenna beam) transmitted in the same predetermined direction. It is worth noting that the working antenna gain (or an adjusted antenna gain) of the working millimeter-wave signal S2 provided by the cooperation of the millimeter-wave antenna module 3, the first reflector 1, and the second reflector 2 can be greater than the original antenna gain (or the unadjusted antenna gain) of the raw millimeter-wave signal S1 provided by the millimeter-wave antenna module 3. In other words, when the millimeter-wave antenna 32 of the millimeter-wave antenna module 3 can be configured to selectively provide the original millimeter-wave signal S1, the original millimeter-wave signal S1 provided by the millimeter-wave antenna 32 of the millimeter-wave antenna module 3 can pass through at least one focusing lens 33 (or be focused by at least one focusing lens 33) and be reflected sequentially by the first signal reflecting surface 1002 of the first reflecting plate 1 and the second signal reflecting surface 2002 of the second reflecting plate 2 to form a working millimeter-wave signal S2 transmitted in the same predetermined direction. For example, the wavelength of the original millimeter-wave signal S1 can be between 1 mm and 10 mm (e.g., any positive integer between 1 mm and 10 mm), and the frequency of the original millimeter-wave signal S1 can be between 28 GHz and 300 GHz (e.g., any positive integer between 28 GHz and 300 GHz). In one feasible embodiment, when the frequency of the original millimeter-wave signal S1 is set to approximately 28 GHz, the original antenna gain of the original millimeter-wave signal S1 provided by the millimeter-wave antenna module 3 (e.g., using a single microstrip patch antenna element 300 and at least one focusing lens 33) can reach approximately 16 dBi (wherein, the antenna gain of the millimeter-wave signal provided by the single microstrip patch antenna element 300 can reach approximately 6 dBi), and the working antenna gain of the working millimeter-wave signal S2 provided by the cooperation of the millimeter-wave antenna module 3, the first reflector 1, and the second reflector 2 can reach approximately 24 dBi. However, the examples given above are merely feasible embodiments and are not intended to limit the present invention.

[0029] Beneficial effects of the embodiments

[0030] One of the beneficial effects of the present invention is that the high-gain millimeter-wave antenna structure M provided by the present invention, through the technical solutions of "millimeter-wave antenna module 3 being disposed between the first reflector 1 and the second reflector 2", "the first recessed region 100 of the first reflector 1 being smaller than the second recessed region 200 of the second reflector 2", "the first recessed region 100 of the first reflector 1 facing the second recessed region 200 of the second reflector 2", "the first reflector 1 having a first focusing region", and "the second reflector 2 having a second focusing region", allows the millimeter-wave antenna module 3 to be configured to selectively provide a raw millimeter-wave signal S1, which can be sequentially reflected by the first reflector 1 and the second reflector 2 to form a working millimeter-wave signal S2 transmitted in the same predetermined direction. It is worth noting that the working antenna gain of the working millimeter-wave signal S2 provided by the cooperation of the millimeter-wave antenna module 3, the first reflector 1, and the second reflector 2 can be greater than the original antenna gain of the raw millimeter-wave signal S1 provided by the millimeter-wave antenna module 3.

[0031] One beneficial effect of the present invention is that the millimeter-wave antenna module 3 provided by the present invention, through the technical solutions of "the millimeter-wave antenna module 3 may include a millimeter-wave antenna 32 and at least one focusing lens 33" and "the millimeter-wave antenna 32 is disposed within the focusing area of ​​a first lens of the at least one focusing lens 33", enables the original millimeter-wave signal S1 provided by the millimeter-wave antenna 32 of the millimeter-wave antenna module 3 to pass through the at least one focusing lens 33 when the millimeter-wave antenna 32 of the millimeter-wave antenna module 3 is configured to selectively provide an original millimeter-wave signal S1. Therefore, the original millimeter-wave signal S1 provided by the millimeter-wave antenna module 3 through the cooperation of the millimeter-wave antenna 32 and the at least one focusing lens 33 can be reflected sequentially by the first reflector 1 and the second reflector 2 to form a working millimeter-wave signal S2 transmitted in the same predetermined direction. It is worth noting that the working antenna gain of the working millimeter-wave signal S2 provided by the cooperation of the millimeter-wave antenna module 3, the first reflector 1, and the second reflector 2 can be greater than the original antenna gain of the original millimeter-wave signal S1 provided by the millimeter-wave antenna module 3.
