Description

An antenna combiner Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an antenna combiner. Background Technology

[0002] In current antenna combiners, most capacitive flying masts are fixed by welding together a support pad and a flying mast plate. In this process, the thickness tolerance of the support pad must not exceed ±0.02mm. Therefore, the requirements for the processing of the pad are extremely high, and the scrap rate of welding and the installation requirements of the components are also very high. Summary of the Invention

[0003] To overcome the shortcomings of the above-mentioned antenna combiner, such as extremely high processing requirements for the support pads, high scrap rate, and high installation requirements, the purpose of this invention is to provide an antenna combiner that simplifies the installation steps and reduces the scrap rate.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: an antenna combiner, comprising:

[0005] Multiple high-frequency resonators are arranged side by side along a first direction, each high-frequency resonator extends along a second direction and includes high-frequency high-resistance lines and high-frequency low-resistance lines distributed along the second direction, wherein two high-frequency resonators have mounting holes on their high-frequency high-resistance lines.

[0006] The flying rod assembly includes a capacitive flying rod and a heat shrink tubing. The capacitive flying rod has two flying rod pins, each of which is fitted with a heat shrink tubing. The two flying rod pins are respectively inserted into mounting holes on two high-frequency, high-resistance lines.

[0007] The fly rod support is fixed to the high-frequency, high-resistance line between two high-frequency, high-resistance lines with mounting holes, and the fly rod assembly is supported on the fly rod support.

[0008] In this technical solution, heat shrink tubing is used to install on the two pins of the capacitive fly rod to prevent the capacitive fly rod from directly contacting the high-frequency, high-resistance wire and causing a short circuit. Fly rod supports are used instead of the original method of using support pads and fly rod plates, which facilitates installation. Mounting holes are used instead of the original welding method, which simplifies the installation steps, reduces the scrap rate, and compared with support pads, heat shrink tubing has better stability performance and can better insulate the capacitive fly rod from the high-frequency, high-resistance wire, thereby improving the overall stability of the component.

[0009] In some embodiments, the high-frequency, high-resistance line also has a fly rod support fixing position. The fly rod support has a high-resistance line locking opening and a fly rod locking opening. The fly rod support is fixed to the fly rod support fixing position through the high-resistance line locking opening, and the fly rod support supports the fly rod assembly through the fly rod locking opening.

[0010] In this technical solution, the high-resistance wire opening and the fly rod opening are used to install the fly rod support on the high-frequency high-resistance wire and to install the fly rod assembly on the fly rod support. This facilitates installation and disassembly, improves the overall stability of the components, and reduces the scrap rate of the components.

[0011] In some embodiments, the antenna combiner further includes high-frequency connecting ribs, and multiple high-frequency resonators include a first high-frequency resonator, a second high-frequency resonator, and a third high-frequency resonator. High-frequency connecting ribs are provided between the first high-frequency resonator, the second high-frequency resonator, and the third high-frequency resonator. Multiple high-frequency resonators, a fly rod assembly, a fly rod support, and high-frequency connecting ribs constitute a high-frequency band filter.

[0012] In this technical solution, the capacitive flybar can generate capacitive cross-coupling in the low-frequency band, which can achieve better out-of-band suppression. In addition, the two high-frequency connecting ribs between the mounting holes can also generate strong capacitive cross-coupling with the capacitive flybar, achieving better out-of-band suppression.

[0013] In some implementations, the antenna combiner further includes:

[0014] Multiple low-frequency resonators are arranged side by side along a first direction. Each low-frequency resonator extends along a second direction and includes low-frequency high-resistance lines and low-frequency low-resistance lines distributed along the second direction. Inductive flying rod welding points are provided on the low-frequency low-resistance lines of two low-frequency resonators.

[0015] Sensitive fly stick, sensitive fly stick welded to sensitive fly stick weld point.

[0016] In this technical solution, the inductive fly rod is welded through inductive welding points, which makes the installation of the inductive fly rod easier.

[0017] In some implementations, low-frequency connecting rods are provided between the low-frequency resonators, and multiple low-frequency resonators, inductive flybars, and low-frequency connecting rods constitute a low-frequency filter.

[0018] In this technical solution, the inductive fly rod can generate inductive cross-coupling in the high-frequency band, which can achieve better out-of-band suppression. Furthermore, the two low-frequency connecting ribs between the welding points of the inductive fly rod can also generate inductive cross-coupling with the inductive fly rod, achieving better out-of-band suppression.

[0019] In some embodiments, the antenna combiner further includes a common resonator, the low-frequency resonator includes a fourth low-frequency resonator, the common resonator is connected to a third high-frequency resonator via a high-frequency connecting rod, and the common resonator is connected to the fourth low-frequency resonator via a low-frequency connecting rod.

[0020] In this technical solution, a high-frequency filter and a low-frequency filter are combined into an antenna combiner through a common resonator, a high-frequency connecting rod, and a low-frequency connecting rod.

[0021] In some implementations, the system also includes a board body, a test cover, a shielding cover, and a connector. The high-frequency resonator, the low-frequency resonator, and the common resonator are located inside the board body. The test cover covers the upper side of the board body, the shielding cover covers the lower side of the board body, and the connector is located on the side of the board body.

[0022] In this technical solution, the board protects internal components such as high-frequency resonators, low-frequency resonators, common resonators, inductive flying rods, and capacitive flying rods. The debugging cover and shielding cover can shield signals and prevent external signal interference. The connector is used to connect the antenna combiner to external facilities for signal interaction.

[0023] In some implementations, the connectors include a high-frequency connector, a low-frequency connector, and a common terminal connector. The high-frequency connector has high-frequency wiring, the low-frequency connector has low-frequency wiring, and the common terminal connector has common terminal wiring. The high-frequency connector is connected to a high-frequency filter via the high-frequency wiring, the low-frequency connector is connected to a low-frequency filter via the low-frequency wiring, and the common terminal connector is connected to a common resonator via the common terminal wiring.

[0024] In this technical solution, the high-frequency connector and high-frequency wiring, the low-frequency connector and low-frequency wiring, and the common terminal connector and common terminal wiring can respectively combine different signals into the inside of the antenna combiner.

[0025] The beneficial effects of this invention are that by using heat shrink tubing to install at both ends of a capacitive fly rod to form a fly rod assembly, fixing the fly rod assembly in the mounting hole, and using a fly rod support to support the capacitive fly rod, the original gasket method is replaced, resulting in better overall component stability and greatly simplifying the steps and processing difficulty of capacitive fly rod installation.

[0042] x is the first direction, and y is the second direction. Detailed Implementation

[0043] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0044] Referring to Figures 1 to 3, an embodiment of this application provides an antenna combiner, including: multiple high-frequency resonators, a flying rod assembly 2, and a flying rod support 3.

[0045] For example, Figures 1 to 3 show that the antenna combiner has four high-frequency resonators, but the embodiments of this application do not limit the number of high-frequency resonators. The following description uses four high-frequency resonators as an example. For ease of description, the four high-frequency resonators are defined as the first high-frequency resonator 15, the second high-frequency resonator 16, the third high-frequency resonator 17, and the eighth high-frequency resonator 19, respectively.

[0046] Taking the horizontal direction (x) as an example and the vertical direction (y) as an example, the first high-frequency resonator 15, the second high-frequency resonator 16, the third high-frequency resonator 17, and the eighth high-frequency resonator 19 are arranged side by side along the first direction (x). The first high-frequency resonator 15, the second high-frequency resonator 16, the third high-frequency resonator 17, and the eighth high-frequency resonator 19 extend along the second direction (y). Each of the first high-frequency resonator 15, the second high-frequency resonator 16, the third high-frequency resonator 17, and the eighth high-frequency resonator 19 includes a high-frequency high-resistance line 11 and a high-frequency low-resistance line 12 distributed along the second direction (y). The high-frequency high-resistance lines 11 of the first high-frequency resonator 15 and the third high-frequency resonator 17 have mounting holes 13.

[0047] Referring to Figure 1, the above-mentioned flying rod assembly 2 includes a capacitive flying rod 21 and a heat shrink tubing 22. The capacitive flying rod 21 has two flying rod pins 211, and the two flying rod pins 211 of the capacitive flying rod 21 are respectively fitted with heat shrink tubing 22. After the heat shrink tubing 22 is fitted, the two flying rod pins 211 of the capacitive flying rod 21 are respectively inserted into the mounting holes 13 on the two high-frequency high-resistance lines 11.

[0048] Referring to Figures 2 and 3, the aforementioned fly rod support 3 is fixed to the high-frequency high-resistance line 11 of the second high-frequency resonator 16 between two high-frequency high-resistance lines 11 with mounting holes 13, and the fly rod assembly 2 is supported on the fly rod support 3.

[0049] In this embodiment, the heat-shrink tubing 22 is fitted onto the two fly rod pins 211 of the capacitive fly rod 21 to form a fly rod assembly 2. The fly rod assembly 2 is then fixedly installed within the mounting hole 13, meaning the heat-shrink tubing 22 and the two fly rod pins 211 of the capacitive fly rod 21 are fixedly installed within the mounting hole 13. The aforementioned fly rod support 3 is fixed to the high-frequency, high-resistance line 11 of the second high-frequency resonator 16 to fix the fly rod assembly 2. Exemplarily, the heat-shrink tubing 22 is made of PTFE (polytetrafluoroethylene), which has insulating properties to prevent direct contact between the capacitive fly rod 21 and the high-frequency, high-resistance line 11, thus avoiding a short circuit in the capacitive fly rod 21. Exemplarily, the capacitive fly rod 21 is made of silver-plated copper wire.

[0050] In this embodiment, heat shrink tubing 22 is used to install on the two fly rod pins 211 of the capacitive fly rod 21 to prevent the capacitive fly rod 21 from directly contacting the high-frequency high-resistance line 11 and forming a short circuit. Fly rod support 3 is used instead of the original method of using support pads and fly rod pieces, which facilitates installation. Mounting holes 13 are used instead of the original welding method, which simplifies the installation steps, reduces the scrap rate, and compared with support pads, heat shrink tubing 22 has better stability performance and can better insulate the capacitive fly rod 21 from the high-frequency high-resistance line 11, thereby improving the overall stability of the component.

[0051] Referring to Figures 2, 3, and 6, in some embodiments, the high-frequency, high-resistance line 11 of the second high-frequency resonator 16 also has a fly rod support fixing position 14. The fly rod support 3 has a high-resistance line locking opening 31 and a fly rod locking opening 32. The fly rod support fixing position 14 and the high-resistance line locking opening 31 of the fly rod support 3 are structurally matched, and the fly rod support 3 is fixed to the fly rod support fixing position 14 through the high-resistance line locking opening 31. The fly rod locking opening 32 on the fly rod support 3 is structurally matched with the capacitive fly rod 21 of the fly rod assembly 2, and the fly rod support 3 supports the fly rod assembly 2 through the fly rod locking opening 32. For example, the above-mentioned fly rod support 3 is made of Ultem (polyetherimide) 1000 material. The fly rod support 3 and the heat shrink tubing 22 replace the original method of fixing the capacitive fly rod 21 with a gasket, which can greatly simplify the installation of the capacitive fly rod 21.

[0052] Continuing with reference to Figures 1 and 2, in some embodiments, the antenna combiner further includes a high-frequency connecting rib 18. A high-frequency connecting rib 18 is provided between the first high-frequency resonator 15 and the second high-frequency resonator 16, between the second high-frequency resonator 16 and the third high-frequency resonator 17, and between the third high-frequency resonator 17 and the common resonator 6. The first high-frequency resonator 15, the second high-frequency resonator 16, the third high-frequency resonator 17, the eighth high-frequency resonator 19, the flying rod assembly 2, the flying rod support 3, and the high-frequency connecting rib 18 constitute a high-frequency band filter 1.

[0053] In the high-frequency filter 1, the capacitive flybar 21 can generate capacitive cross-coupling, and the capacitive flybar 21 can also generate capacitive cross-coupling with the two high-frequency connecting rods 18 between the first high-frequency resonator 15, the second high-frequency resonator 16, and the third high-frequency resonator 17. Using the quality factor Q to represent the filter's performance, while keeping the Q value constant, the spacing between high-frequency resonators after adding capacitive cross-coupling can be increased compared to high-frequency resonators without it. This makes the fabrication and installation of individual high-frequency resonators more convenient, providing greater operating space.

[0054] In some implementations, the position of the mounting hole 13 on the high-frequency high-impedance line 11 can be set. The closer the mounting hole 13 is to the high-frequency low-impedance line 12, the weaker the capacitive cross-coupling between the capacitive fly rod 21 and the resonator. The farther the mounting hole 13 is from the high-frequency low-impedance line 12, the stronger the capacitive cross-coupling between the capacitive fly rod 21 and the resonator. The position of the mounting hole 13 can be set according to different requirements.

[0055] Referring again to Figures 1 and 2, in some embodiments, the antenna combiner further includes four low-frequency resonators. This application does not limit the number of low-frequency resonators; the following description uses four low-frequency resonators as an example. The low-frequency resonator 4 includes a fourth low-frequency resonator 44, a fifth low-frequency resonator 45, a sixth low-frequency resonator 46, and a seventh low-frequency resonator 48. The fourth low-frequency resonator 44, the fifth low-frequency resonator 45, the sixth low-frequency resonator 46, and the seventh low-frequency resonator 48 are arranged side by side along a first direction x. The fourth low-frequency resonator 44, the fifth low-frequency resonator 45, the sixth low-frequency resonator 46, and the seventh low-frequency resonator 48 extend along a second direction y. Each of the fourth low-frequency resonator 44 and the sixth low-frequency resonator 46 includes a low-frequency high-resistance line 41 and a low-frequency low-resistance line 42 distributed along the second direction y. Inductive fly rod welding points 43 are provided on the fourth low-frequency resonator 44 and the sixth low-frequency resonator 46. An inductive fly rod 5 is welded to the inductive fly rod welding point 43. For example, the inductive fly rod 5 is made of silver-plated copper wire.

[0056] Referring to Figures 2 to 4, in some embodiments, low-frequency connecting ribs 47 are provided between the fourth low-frequency resonator 44 and the fifth low-frequency resonator 45, between the fifth low-frequency resonator 45 and the sixth low-frequency resonator 46, between the sixth low-frequency resonator 46 and the seventh low-frequency resonator 48, and between the fourth low-frequency resonator 44 and the common resonator 6. The low-frequency connecting ribs 47, together with the fourth low-frequency resonator 44, the fifth low-frequency resonator 45, the sixth low-frequency resonator 46, the seventh low-frequency resonator 48, and the inductive flybar 5, form a low-frequency filter 4, which filters in the low-frequency range. In device 4, the inductive fly rod 5 can generate inductive cross coupling, and the inductive fly rod 5 can also generate inductive cross coupling with the low-frequency connecting rod 47 between the fourth low-frequency resonator 44, the fifth low-frequency resonator 45, and the sixth low-frequency resonator 46. This can further achieve better out-of-band suppression. Under the same Q value, compared with the low-frequency resonator without inductive cross coupling, the spacing between the low-frequency resonators after adding capacitive cross coupling can be increased, thus making the processing operation of the low-frequency resonator more convenient.

[0057] Referring to Figure 3, this embodiment is a front view of the antenna combiner of the present invention. In some embodiments, the antenna combiner further includes a common resonator 6. As shown in Figure 3, the low-frequency filter 4 and the high-frequency filter 1 are connected through the common resonator 6. The common resonator 6 is connected to the third high-frequency resonator 17 of the high-frequency filter 1 through the high-frequency connecting rod 18. The common resonator 6 is connected to the fourth low-frequency resonator 44 of the low-frequency filter 4 through the low-frequency connecting rod 47, thus forming the antenna combiner.

[0058] Referring to Figures 1 and 4, in some embodiments, the antenna combiner further includes a plate 7, a test cover 8, a shielding cover 9, and connectors 10. As shown in Figures 1 and 4, the high-frequency resonator, the low-frequency resonator, and the common resonator 6 are disposed inside the plate 7, which serves to protect the internal components. The test cover 8 covers the upper side of the plate 7 and has multiple test holes 81. Test bolts 82 can extend out of the combiner test cover 8 through the test holes 81, and the performance of the combiner can be adjusted by the test bolts 82. The shielding cover 9 covers the lower side of the plate 7, and three connectors 10 are disposed on the side of the plate 7.

[0059] Referring to Figures 4 and 5, in some embodiments, the connector 10 includes a high-frequency connector 101, a low-frequency connector 102, and a common terminal connector 103. The high-frequency connector 101 has a high-frequency wiring 1011, the low-frequency connector 102 has a low-frequency wiring 1021, and the common terminal connector 103 has a common terminal wiring 1031. The eighth high-frequency resonator 19 in the high-frequency filter 1 has a high-frequency wiring slot 191, the seventh low-frequency resonator 48 in the low-frequency filter 4 has a low-frequency wiring slot 481, and the common resonator 6 has a common terminal connector 1031. The high-frequency connector 101 is connected to and fixed to the high-frequency wiring slot 191 of the eighth high-frequency resonator 19 in the high-frequency filter 1 via the high-frequency wiring 1011. The low-frequency connector 102 is connected to and fixed to the low-frequency wiring slot 481 of the seventh low-frequency resonator 48 in the low-frequency filter 4 via the low-frequency wiring 1021. The common terminal connector 103 is connected to the common wiring slot 61 of the common resonator 6 via the common wiring slot 1031. The three connectors are located on the side of the board 7. The connectors are standard N-type connectors or RG-401 cables.

[0060] In some implementations, after the fly rod assembly 2 is installed into the mounting hole 13 on the high-frequency high-resistance line 11, the capacitive fly rod 21 does not directly contact the board body 7 and the debugging cover plate 8, so as to avoid short circuit of the capacitive fly rod 21.

[0061] In summary, this application provides an antenna combiner that uses heat-shrink tubing 22 to mount on two fly rod pins 211 of a capacitive fly rod 21 to form a fly rod assembly 2. The fly rod assembly 2 is fixed in the mounting hole 13, and a fly rod support 3 is used to support the capacitive fly rod 21. This replaces the original gasket method, making the entire assembly more stable and greatly simplifying the installation steps and processing difficulty of the capacitive fly rod 21.

[0062] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
