The phase shifter slides within its sub-cavity to adjust the phase, and the combiner is directly connected to the phase shifter's output port, eliminating the complex connection lines of traditional separate structures. The first and second phase shifters slide within their respective sub-cavities, adjusting the phase by changing the dielectric constant and thus altering the signal transmission path length, ensuring that the dual-band signals do not interfere with each other. The output port of each phase shifter is directly connected to the combiner, combining the phase-shifted multiple signals into a single signal. The corresponding combiners within the first and second sub-cavities are electrically connected to achieve cross-band signal integration, ultimately outputting a composite signal. The combiner is positioned adjacent to the phase shifter's output port, shortening the signal transmission path and reducing impedance mismatch and transmission loss associated with traditional external combiners. Simultaneously, the integrated design reduces insertion loss and reflection loss.
[0022] Therefore, by integrating the phase shifter and combiner into a single cavity, the number of separate components and connection structures is significantly reduced, resulting in a smaller overall size that meets the compact antenna requirements of 5G / IoT devices. The direct connection design of the phase shifter and combiner shortens signal transmission distance and reduces cable loss and interface reflection. The independent layout of the dual-band phase shifters (located in the first and second sub-cavities) avoids crosstalk between frequency bands and reduces energy loss during phase shifting. Integration reduces insertion loss, and combined with an optimized signal path, improves the antenna system's gain and radiation efficiency. The sliding phase shifter supports flexible phase adjustment, adapting to beamforming requirements in various scenarios and enhancing communication quality. The integrated cavity design reduces external connection nodes, lowers assembly complexity, and reduces the risk of failure due to loose connections, improving system stability.

[0038] In related technologies, with the rapid development of wireless communication technology, especially the popularization of 5G and the Internet of Things, the requirements for antennas and RF combiners are increasing. As the core component of wireless communication, traditional combiners and antennas are too large to meet the miniaturization and integration requirements of modern equipment. Therefore, the technology of miniaturized integrated combiner antennas has emerged, and miniaturized integrated combiner antenna technology is an important development direction in the field of wireless communication.
[0039] As shown in Figure 1, Figure 2 , Figure 3 and Figure 5 As shown, in order to solve the above-mentioned technical problems, this application provides an integrated combining phase shifter, which includes:
[0040] A phase shifter cavity 100 has a first sub-cavity 110 and a second sub-cavity 120, the first sub-cavity 110 and the second sub-cavity 120 are arranged side by side, and both the first sub-cavity 110 and the second sub-cavity 120 extend along the length direction of the phase shifter cavity 100;
[0041] A circuit board is located within the phase shifter cavity, and the circuit board includes a phase shifter and a combiner. A phase shifter 600 includes a first phase shifter 600 and a second phase shifter 600, the first phase shifter 600 and the second phase shifter 600 operating at different frequency bands, and the first phase shifter 600 is disposed within the first sub-cavity 110, and the second phase shifter 600 is disposed within the second sub-cavity 120.
[0042] A combiner 700 is provided, wherein the plurality of combiners 700 are distributed within the phase shifter cavity 100, and each output port of the phase shifter 600 is electrically connected to the combiner 700. The combiner 700 is positioned on the phase shifter 600 near the corresponding output port. The combiner 700 in the first sub-cavity 110 and the corresponding combiner 700 in the second sub-cavity 120 are electrically connected.
[0043] In these embodiments, the phase shifter cavity 100 is generally rectangular in shape, and has two parallel-arranged first sub-cavities 110 and second sub-cavities 120 inside. Both the first sub-cavities 110 and the second sub-cavities 120 extend along the length of the phase shifter cavity 100 and are used to accommodate the first phase shifter 600 and the second phase shifter 600, respectively.
[0044] The phase shifter 600 includes a first phase shifter 600 and a second phase shifter 600. For example, the first phase shifter 600 operates in the 2.4GHz band and is suitable for Wi-Fi communication; the second phase shifter 600 operates in the 5.8GHz band and is suitable for millimeter-wave communication. The two phase shifters 600 are slidably mounted in their respective first sub-cavities 110 and second sub-cavities 120 for easy phase matching adjustment. Currently, they are mainly used in most frequency division antennas in China, such as the 4448, 4488, and FA / D antennas. The first and second phase shifters 600 operate independently and can simultaneously achieve different downtilt angles. The phase shifting network is in PCB form.
[0045] Multiple combiners 700 are distributed within the phase shifter cavity 100. Each phase shifter 600's output port is connected to a combiner 700. For example, the two output ports of the first phase shifter 600 are each connected to two combiners 700, and the two output ports of the second phase shifter 600 are also each connected to two combiners 700. These combiners 700 are responsible for combining signals from different phase shifters 600 to achieve unified output or distribution of multi-band signals.
[0046] Furthermore, the combiner 700 in the first sub-cavity 110 and the corresponding combiner 700 in the second sub-cavity 120 are electrically connected through conductive metal strips or microstrip lines, thereby achieving efficient signal transmission and integration.
[0047] A first groove 111 and a second groove 121 are respectively provided on the side walls of the first sub-cavity 110 and the second sub-cavity 120. The two sides of the phase shifter 600 are embedded in the corresponding grooves, allowing it to slide along the length direction within the cavity. By rotating the adjustment knob to drive the lead screw transmission system, the position of the phase shifter 600 can be precisely controlled, thereby achieving fine adjustment of the phase.
[0048] A phase compensation circuit is provided between adjacent combiners 700. This circuit consists of a controllable delay line and an LC resonant element. It is used to correct the phase mismatch caused by path differences, thereby ensuring the phase consistency between each output port and improving the quality of the synthesized signal.
[0049] The aforementioned integrated phase shifter is directly integrated into the antenna feed structure to form an integrated phase shifter antenna device. For example, a phase shifter cavity 100 is set below the patch antenna, and the phase shifter 600 and combiner 700 directly drive the antenna element, avoiding the additional feed line connection in the traditional structure.
[0050] In other words, the integrated phase shifter combines phase shifters 600 (first and second phase shifters 600) and combiner 700 within the same cavity (phase shifter cavity 100). Utilizing the parallel arrangement of the first sub-cavities 110 and 120, it achieves independent phase shifting and combining of dual-band (different operating frequency bands) signals. The phase shifter 600 slides within its sub-cavity to adjust the phase, and the combiner 700 is directly connected to the phase shifter's output port, eliminating the complex wiring of traditional separate structures. The first and second phase shifters 600, located in their respective sub-cavities, adjust the phase by changing the signal path length through a sliding medium, ensuring that the dual-band signals do not interfere with each other. The output port of each phase shifter 600 is directly connected to the combiner 700, combining the phase-shifted multiple signals into a single signal. The corresponding combiners 700 within the first and second sub-cavities 110 and 120 are electrically connected to achieve cross-band signal integration, ultimately outputting a composite signal. The combiner 700 is positioned close to the output port of the phase shifter, which shortens the signal transmission path and reduces impedance mismatch and transmission loss caused by traditional external combiners. At the same time, the integrated design reduces insertion loss and reflection loss.
[0051] Therefore, by integrating the phase shifter and combiner into a common cavity, the number of independent components and connection structures are significantly reduced, resulting in a smaller overall size that meets the compact antenna requirements of 5G / IoT devices. The direct connection design between the phase shifter 600 and combiner 700 shortens the signal transmission distance, reducing cable loss and interface reflection. The independent layout of the dual-band phase shifters (located in the first and second sub-cavities 120) avoids inter-band crosstalk and reduces energy loss during phase shifting. Integration reduces insertion loss, and combined with an optimized signal path, improves the antenna system's gain and radiation efficiency. The sliding phase shifter 600 supports flexible phase adjustment, adapting to beamforming requirements in various scenarios and enhancing communication quality. The integrated cavity design reduces external connection nodes, lowers assembly complexity, and reduces the risk of failure due to loose connections, improving system stability.
[0052] like Figure 4 As shown, in some embodiments, the integrated combiner phase shifter further includes multiple connecting pins, which pass through the pin holes of the combiner 700 in the corresponding first sub-cavity 110 and the corresponding pin holes of the combiner 700 in the second sub-cavity 120, and are electrically connected to the corresponding combiner 700.
[0053] In these embodiments, this embodiment provides an improved integrated combiner phase shifter structure, which further includes a plurality of connecting pins for realizing electrical connection between corresponding combiners 700 in the first sub-cavity 110 and the second sub-cavity 120.
[0054] A connecting pin passes between the combiner 700 in the first sub-cavity 110 and the corresponding combiner 700 in the second sub-cavity 120. Each combiner 700 has a pin hole, the position of which is precisely designed so that when the connecting pin is inserted, it can pass through the pin holes of the two corresponding combiners 700 in the first sub-cavity 110 and the second sub-cavity 120 simultaneously, and form a good electrical connection with these two combiners 700.
[0055] Specifically, the connecting pin is made of a conductive material, such as copper or gold-plated brass, to ensure good conductivity. The pin surface can be treated with an anti-oxidation process to improve connection stability. Both ends of the pin have elastic locking mechanisms that automatically lock in place after insertion, preventing loosening. The pin holes in the combiner 700 are surrounded by solder pads or metal rings to enhance the contact area with the connecting pin and improve electrical connection reliability. The connecting pin not only provides mechanical fixation but also serves as part of the signal transmission path, effectively connecting the combiners 700 in different sub-cavities to enable coordinated operation of multi-band signals.
[0056] By setting a connecting pin, efficient electrical connection between components in two sub-cavities can be achieved without adding extra wiring, thereby further reducing the overall structural size, reducing insertion loss, and improving the stability and maintainability of the system.
[0057] For example, in this embodiment, the connecting pin and the combiner 700 are soldered together.
[0058] like Figure 5 As shown, in some embodiments, the integrated phase shifter further includes a sliding medium 300. The first sub-cavity 110 and the second sub-cavity 120 both contain the sliding medium 300, and the sliding medium 300 is connected to the phase shifter 600 in the corresponding sub-cavity.
[0059] In these embodiments, an improved phase shifter adjustment structure is provided, wherein the integrated combining phase shifter further includes a sliding medium 300 for assisting the sliding adjustment of the phase shifter 600 within the sub-cavity and optimizing its electrical performance.
[0060] The sliding medium 300 is disposed inside both the first sub-cavity 110 and the second sub-cavity 120. The sliding medium 300 is connected to the phase shifter 600 in the corresponding sub-cavity and can slide along the length of the cavity together with the phase shifter 600. At the same time, the sliding medium 300, as a supporting medium, also has certain dielectric properties, which can affect the electromagnetic field distribution of the microstrip line or waveguide structure in the phase shifter 600, thereby realizing continuous phase adjustment.
[0061] The sliding medium 300 consists of upper and lower parts that sandwich the phase shifter 600 in the middle. Small clips at the top and bottom fix it in place, and sliding it achieves phase change of the phase shifter, thereby changing the antenna tilt angle.
[0062] like Figure 4 and Figure 5 As shown, in some embodiments, the sliding medium 300 has a first portion and a second portion, and the phase shifter 600 is clamped between the first portion and the second portion.
[0063] In these embodiments, an improved sliding medium 300 structure is provided, the sliding medium 300 having a first part and a second part, the phase shifter 600 being clamped between the first part and the second part, thereby achieving stable support and sliding guidance for the phase shifter 600.
[0064] The first and second parts of the sliding medium 300 are respectively disposed on the upper and lower sides or the left and right sides of the phase shifter 600 (depending on the internal layout of the cavity), and its cross-sectional shape is preferably "C" or "U" shaped, which can closely fit the outer wall of the phase shifter 600 to form a clamping structure.
[0065] Specifically, both the first and second parts are made of insulating materials with low dielectric constant and low loss, such as polytetrafluoroethylene (PTFE) and ceramic composite materials. The first and second parts are detachably connected by means of clips, screws, or adhesives, facilitating the installation and replacement of the phase shifter 600.
[0066] In the clamped state, the phase shifter 600 is firmly fixed inside the sliding medium, preventing displacement or vibration during sliding, thereby ensuring the stability of signal transmission.
[0067] like Figure 1 As shown, in some embodiments, the integrated phase shifter also includes a feeder base 500, which is welded to the phase shifter cavity 100. The feeder base 500 is located outside the phase shifter cavity 100 and is welded to the cable.
[0068] In these embodiments, the integrated combiner phase shifter also includes a feeder base 500 for achieving a stable electrical connection with an external cable, ensuring efficient transmission of high-frequency signals.
[0069] The feeder base 500 is welded and fixed to the outer wall of the phase shifter cavity 100, and forms a conductive connection with the phase shifter 600 or combiner 700 inside the cavity. One end of the feeder base 500 extends into the phase shifter cavity 100 and is welded to the corresponding circuit part (e.g., microstrip line, waveguide structure, etc.), while the other end is located outside the phase shifter cavity 100 for welding to external cables.
[0070] For example, the feeder 500 is preferably an SMA, N-type, or other standard RF connector suitable for the RF / microwave band.
[0071] The metal casing of the feeder connector 500 is soldered to the pre-drilled holes in the phase shifter cavity 100 using conductive solder (such as silver solder paste or tin-lead solder), ensuring good mechanical fixation and electromagnetic shielding performance. The center conductor of the feeder connector 500 is connected to the signal transmission line in the internal circuit via coaxial soldering, ensuring low-loss transmission of high-frequency signals. One end of the external cable is screwed or soldered to the feeder connector 500, forming a robust electrical connection path to introduce or extract radio frequency signals into or out of the phase shifter system.
[0072] The solution eliminates the need for electroplating of the cavity. The connection between the feeder 500 and the cavity is achieved through laser welding. Compared to the traditional full electroplating solution for the cavity, the electroplating-free cavity combined with the laser welding of the feeder 500 reduces environmental pollution and meets the needs of green, economical, and sustainable development. This significantly reduces the overall cost of the antenna while ensuring performance.
[0073] like Figure 1 As shown, in some embodiments, the integrated phase shifter further includes a fixing clip 400, which is disposed on the phase shifter cavity 100 and located outside the phase shifter cavity 100. The cable and the fixing clip 400 are engaged.
[0074] In these embodiments, the fixing buckle 400 is disposed on the phase shifter cavity 100 and located outside the phase shifter cavity 100, and can be engaged with the cable to ensure the safety and reliability of the cable connection.
[0075] The retaining clip 400 is designed to be installed on the phase shifter cavity 100 near the feeder base 500 to provide additional support and fixation, preventing the cable from being directly subjected to external stress and causing interface damage.
[0076] Specifically, the retaining clip 400 can be made of elastic plastic, metal, or other materials with sufficient strength and flexibility. Its shape is typically designed as a loop or clip with an opening to facilitate quick installation and removal of cables.
[0077] The retaining clip 400 is installed adjacent to the feeder base 500 on the outside of the phase shifter cavity 100. This ensures that after the cable is connected to the feeder base 500, it can be further secured by the clip, reducing connection instability caused by movement or vibration. The retaining clip 400 has an anti-slip texture or rubber gasket inside. After the cable is inserted and passes through the feeder base 500, it is placed into the retaining clip 400, and the clip tightly wraps around the cable sheath, forming a secure mechanical connection. Some designs may also include adjusting screws or locking devices to further enhance the tightness of the fixation.
[0078] By setting the fixing clip 400, the connection stability between the cable and the phase shifter cavity 100 is significantly enhanced, the service life of the interface is extended, and the on-site wiring and maintenance work is simplified, thereby improving the reliability and ease of use of the system.
[0079] like Figure 4 As shown, in some embodiments, the two opposite sidewalls of the first sub-cavity 110 are provided with first sliding grooves 111, the first sliding grooves 111 extend along the length direction of the phase shifter cavity 100, and the two ends of the first phase shifter 600 are respectively slidably inserted into the corresponding first sliding grooves 111.
[0080] The second sub-cavity 120 has two opposite sidewalls with second sliding grooves 121. The second sliding grooves 121 extend along the length of the phase shifter cavity 100, and the two ends of the second phase shifter 600 slide through the corresponding second sliding grooves 121 respectively.
[0081] In these embodiments, an improved sliding guide structure for the phase shifter 600 is provided. The first sliding groove 111 is provided on the two opposite side walls of the first sub-cavity 110. The first sliding groove 111 extends along the length direction of the phase shifter cavity 100. The two ends of the first phase shifter 600 are respectively slidably inserted into the corresponding first sliding groove 111, thereby realizing its stable sliding along the length direction of the cavity.
[0082] Similarly, the second sub-cavity 120 has two opposite sidewalls provided with second sliding grooves 121, which also extend along the length of the phase shifter cavity 100; the two ends of the second phase shifter 600 are respectively slidably inserted into the corresponding second sliding grooves 121 to achieve smooth movement.
[0083] The first groove 111 and the second groove 121 are straight grooves with cross-sections that can be rectangular, U-shaped, or T-shaped, etc. The specific shape can be matched according to the sliding component at the end of the phase shifter 600. The lengths of the first groove 111 and the second groove 121 are the same as or slightly shorter than the length of the phase shifter cavity 100 to ensure that the phase shifter 600 can be freely adjusted within a set range.
[0084] The first phase shifter 600 and the second phase shifter 600 are respectively provided with sliding components, such as guide rails, ball sliders or slide rod structures, at both ends to match the slide grooves. These sliding components are embedded in the corresponding slide grooves and can slide along the length of the slide groove under the drive of external force.
[0085] The phase shifter 600 can be slid by an external adjustment knob, lead screw mechanism or electric drive device to achieve precise phase adjustment.
[0086] like Figure 4 As shown, in some embodiments, the integrated phase shifter further includes a transmission buckle 200. The side of the phase shifter cavity 100 has a third sliding groove, which extends along the length of the phase shifter cavity 100. The sliding medium 300 has a slot, and one end of the transmission buckle 200 passes through the third sliding groove and engages with the slot.
[0087] In these embodiments, the transmission latch 200 is disposed outside the phase shifter cavity 100 and engages with a slot on the sliding medium 300, thereby achieving precise sliding control of the phase shifter 600. A third sliding groove is provided on the side of the phase shifter cavity 100, extending along the length of the phase shifter cavity 100; a slot is provided on the sliding medium 300; one end of the transmission latch 200 passes through the third sliding groove and engages with the slot, thereby driving the sliding medium 300 and the phase shifter 600 it holds to slide synchronously.
[0088] The third groove is formed on the outer wall of the phase shifter cavity 100, preferably a straight groove or an opening structure. The length of the groove matches the movable range of the phase shifter 600, ensuring that the transmission latch 200 can slide freely within a set range.
[0089] The transmission buckle 200 is preferably made of metal or high-strength engineering plastic, and has good wear resistance and deformation resistance.
[0090] For example, one end of the buckle is provided with an elastic buckle head or ball structure, which can be embedded in the third sliding groove and slide along it; the other end is designed as a hook or protrusion structure that can cooperate with the slot on the sliding medium 300.
[0091] The first or second part of the sliding medium 300 is provided with at least one slot, the shape of which matches the snap-fit end of the transmission buckle 200; when the transmission buckle 200 slides along the third slide groove to the designated position, its snap-fit end automatically snaps into the corresponding slot; thereafter, pushing the transmission buckle 200 can drive the sliding medium 300 and the phase shifter 600 clamped therein to move together.
[0092] For example, the transmission buckle 200 can be connected to a manual knob, a lead screw mechanism, or an electric drive device to achieve remote or manual adjustment.
[0093] like Figure 6 As shown, in some embodiments, this application also provides an antenna, which includes a radiating element, an antenna backplate 800, and an integrated combiner phase shifter as described in any of the above embodiments; wherein the phase shifter 600 is electrically connected to the radiating element, and the phase shifter cavity 100 is disposed on the antenna backplate 800.
[0094] This embodiment provides an antenna device using the aforementioned integrated combiner phase shifter, achieving an integrated design of multi-band phase shifting, combining, and high-efficiency radiation of radio frequency signals. The antenna includes:
[0095] Radiation element: can be a patch antenna, dipole antenna, Vivaldi antenna, or other radiation structure suitable for high-frequency communication, used to convert electrical signals into electromagnetic waves for outward transmission;
[0096] Antenna backplate 800: Made of metal materials (such as aluminum, copper) or conductive composite materials, it has good mechanical support and electromagnetic shielding performance;
[0097] Integrated combiner phase shifter: As described in any of the preceding embodiments, it is fixedly mounted on the antenna backplane 800 and serves as part of the antenna feed network.
[0098] Specifically, the integrated phase shifter is securely mounted on the antenna backplate 800 using screws, welding, or clips to ensure mechanical stability and electrical continuity between it and the overall antenna structure. The output port of the phase shifter 600 is electrically connected to the corresponding radiating element via microstrip lines, coaxial cables, or direct welding.
[0099] In some preferred embodiments, the output port of phase shifter 600 can be directly integrated near the feed point of the radiating element, reducing the transmission path length and insertion loss. Combiner 700 is responsible for combining signals from different frequency bands or channels, and then phase adjustment is performed by phase shifter 600 to ultimately drive the radiating element to achieve directional radiation.
[0100] In some embodiments, the transmission latch 200 is located on the side of the phase shifter cavity 100 opposite to the antenna backplate 800.
[0101] In these embodiments, after the integrated combining phase shifter is mounted on the antenna backplane 800, the entire phase shifter cavity 100 has two main directional surfaces: one facing the antenna backplane 800 and the radiating element; and the other facing away from the antenna backplane 800, i.e., facing the equipment housing or maintenance side.
[0102] In this embodiment, the transmission buckle 200 is located on the side away from the antenna backplate 800, so that the user can adjust the position of the phase shifter 600 without disassembling the antenna structure.
[0103] Specifically, the transmission latch 200 is disposed on the outer wall of the phase shifter cavity 100 via a third sliding groove; the third sliding groove extends along the length of the phase shifter cavity 100; one end of the transmission latch 200 passes through the third sliding groove and forms a snap-fit engagement with a slot on the sliding medium 300; since it is located on the side opposite to the antenna backplate 800, it can be directly driven by an external knob, push rod, or electric actuator. Furthermore, this layout helps to further reduce the size of the antenna.
[0104] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0105] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0106] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
