Description

Technical Field

[0001] This utility model relates to the field of wireless communication technology, and in particular to a multi-port integrated antenna. Background Technology

[0002] An antenna is a transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. It is a component in wireless equipment used to transmit or receive electromagnetic waves; engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy—anything that uses electromagnetic waves to transmit information—rely on antennas to function.

[0003] CN102694240A discloses a high-performance ultra-wideband VHF / UHF vehicle-mounted antenna, including an antenna element, a shock-absorbing spring, and a fixed antenna mount. The antenna element is connected to the fixed antenna mount via the shock-absorbing spring. The antenna element includes at least two radiating elements and at least one loading resistor. Two adjacent radiating elements are connected by a loading resistor in a straight line structure. The bottom radiating element is connected to a cable socket in the fixed antenna mount via a transmission line.

[0004] Multiport antennas integrate two or more antennas into a single antenna whip, achieving the goal of reducing the number of antennas. However, when such antennas are integrated, the feed line of the upper antenna has a significant impact on the feed line of the lower antenna. The traditional solution is to use a series of choke methods, but these methods often sacrifice some of the gain of the lower antenna, limiting the improvement of the overall antenna performance.

[0041] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0042] like Figure 1-4 As shown, this utility model discloses a multi-port integrated antenna, including an antenna mount 1, two radio frequency connectors 2, an antenna body 3, two radiating components 4, and a choke 5. Both radio frequency connectors 2 are disposed within the antenna mount 1. The antenna body 3 is fixed to the antenna mount 1 and is hollow inside. Both radiating components 4 are disposed within the antenna body 3 and are spaced apart along the axial direction of the antenna body 3. The choke 5 is fixed within the antenna body 3 and located between adjacent radiating components 4. One radio frequency connector 2 is electrically connected to the lower radiating component 4 via a feed line, and the other radio frequency connector 2 is electrically connected to the upper radiating component 4 via a feed line that passes through the choke 5, for transmitting or receiving radio wave signals.

[0043] It should be noted that this multi-port integrated antenna has two RF connectors 2, and they receive RF signals at the same frequency. When the RF signal is input from the RF connector 2, it is transmitted to the corresponding radiating component 4 through the feed line. The radiating component 4 can convert the high-frequency current transmitted from the feed line into electromagnetic waves and radiate them into space, or convert electromagnetic waves in space into high-frequency current and transmit them to the feed line, and then to the RF connector 2 for subsequent equipment processing. For the lower radiating component 4, the RF connector 2 connected to it is directly electrically connected to it through the feed line, and the signal transmission path is relatively direct. For the upper radiating component 4, the RF connector 2 connected to it is wrapped around the feed line and passes through the choke 5 before being electrically connected to it. This feed line arrangement solves the coupling problem between antennas.

[0044] Furthermore, in a multi-port antenna, the feed line of the upper antenna will have a coupling effect on the feed line of the lower antenna, which will lead to a decrease in antenna performance. By using the inductive characteristics of the choke 5, the high-frequency current on the feed line is impeded, reducing the interference of the electromagnetic field generated by the upper antenna feed line on the lower antenna feed line, and reducing the degree of coupling between antennas.

[0045] In this embodiment, by setting a choke 5 between adjacent radiating components 4 and using an upper antenna feed line to wrap around and pass through the choke 5, the coupling interference of the upper antenna feed line to the lower antenna feed line is reduced. This allows each radiating component 4 to work more independently during actual operation, reducing mutual influence and thus improving the overall performance stability of the antenna. Furthermore, while effectively reducing coupling, it does not have a significant negative impact on the antenna gain, enabling the antenna to achieve multi-port integration while maintaining high gain, thereby improving signal transmission and reception capabilities, and enhancing communication distance and signal quality.

[0046] In this embodiment, the antenna mount 1 includes a base 11, a flexible element 12, and a whip mount 13. The base 11 is hollow inside and is fixed to the vehicle body by bolts. Two radio frequency connectors 2 are respectively located on both sides of the base 11 for radio frequency signal transmission. The flexible element 12 is fixed on the base 11 and the interior of the flexible element 12 is connected to the base 11 to provide shock absorption for the antenna body 3. The whip mount 13 is fixed on the side of the flexible element 12 away from the base 11.

[0047] Specifically, in this embodiment, the flexible element 12 is a drum-shaped spring.

[0048] It should be noted that the base 11 is hollow inside and is firmly fixed to the vehicle body with bolts, providing a stable support foundation for the entire antenna mount 1. Two RF connectors 2 are located on both sides of the base 11, which facilitates connection with external devices and realizes stable transmission of RF signals. When the communication equipment on the vehicle body is working, the RF signal is input and output through the RF connectors 2 on both sides of the base 11 to complete the signal transmission. During the operation of the antenna, the vehicle body may generate various vibrations and impacts due to driving, vibration, etc. The drum spring has good elasticity and flexibility. When these vibrations and impacts are transmitted to the antenna mount 1, the drum spring will undergo elastic deformation, and absorb and buffer these energies through its own extension and bending, thereby reducing the impact of vibration and impact on the antenna body 3.

[0049] In this embodiment, the antenna body 3 includes a housing 31 and a cap 32. The housing 31 is fixed on the whip seat 13 and is hollow inside. The cap 32 is disposed at the top of the housing 31 and is sealed to the housing 31.

[0050] Specifically, in this embodiment, the housing 31 is a fiberglass pipe.

[0051] In this embodiment, each of the two radiating components 4 includes two radiating units 41, a liner 42, and a combiner 43. The liner 42 is disposed inside the housing 31 and is arranged concentrically with the housing 31. The two radiating units 41 are sleeved on the outside of the liner 42 and are spaced apart along the axial direction of the liner 42. The combiner 43 is disposed inside the liner 42. The RF connector 2 is connected to the combiner 43 via a feed line to shunt the current, so that the feedback points of the two radiating units 41 are electrically connected.

[0052] It should be noted that the two radiating elements 41 are used by the antenna to realize the functions of radio wave transmission and reception. When there is an input radio frequency signal, current flows in the radiating element 41. According to the principle of electromagnetic induction, the changing current will generate a changing magnetic field around the radiating element 41, thereby exciting electromagnetic waves to radiate into space. Conversely, when there are electromagnetic waves in space, an alternating current will be induced in the radiating element 41, thereby realizing the reception of radio waves. In addition, the liner 42 provides a stable support structure for the radiating element 41. At the same time, the liner 42 is a copper tube, which can reduce the electromagnetic interference between the radiating element 41 and the surrounding environment, guide the electromagnetic waves to radiate into space more effectively, thereby improving the radiation efficiency of the antenna and reducing energy loss.

[0053] In this embodiment, the combiner 43 enables the splitting and combining of radio frequency signals. When transmitting signals, it can reasonably distribute one radio frequency signal to two radiator units 41, allowing the two radiator units 41 to work simultaneously, increasing the antenna's transmission power and signal strength. When receiving signals, it can combine the weak signals received by the two radiator units 41, improving the signal-to-noise ratio and enhancing the antenna's ability to receive weak signals, thereby improving the reliability and stability of the entire communication system.

[0054] In this embodiment, the feed points of the two adjacent radiator units 41 are both located on the side and are arranged in a centrally symmetrical manner along the center point of the liner tube 42.

[0055] It should be noted that this layout makes the current distribution on the radiating element 41 more uniform and symmetrical. The uniform and symmetrical current distribution and the lower coupling effect make the antenna more adaptable to environmental changes during operation, improve the reliability and stability of the antenna in complex environments, and reduce communication interruptions and performance fluctuations caused by environmental factors.

[0056] Specifically, in this embodiment, each radiator unit 41 includes a first radiator 411 and a second radiator 412. The first radiator 411 and the second radiator 412 are both disposed inside the housing 31 and sleeved on the outside of the liner 42, and are spaced apart along the axial direction of the liner 42. The two ends of the core ground of the feed line are electrically connected to the feed points of the first radiator 411 and the second radiator 412 respectively to form a circuit.

[0057] It should be noted that the two ends of the feed line core are electrically connected to the feed points of the first radiator 411 and the second radiator 412 respectively to form a loop, providing a complete path for the stable flow of current. When transmitting a signal, the alternating current provided by the radio frequency signal source flows in the loop, driving the two radiators to radiate electromagnetic waves. When receiving a signal, the electromagnetic waves in space induce alternating currents on the two radiators, which are transmitted to the receiving device for processing through the loop.

[0058] This embodiment also includes a first feeder assembly 6, which includes a first feeder 61, a second feeder 62, and a third feeder 63. One end of the first feeder 61 is electrically connected to the RF connector 2, and the other end extends into the bushing 42 and is electrically connected to the first connection terminal of the combiner 43. One end of the second feeder 62 is electrically connected to the second connection terminal of the combiner 43, and the core end of the other end is electrically connected to the feedback point of the first radiator 411 located below, and the ground end of the other end is electrically connected to the feedback point of the second radiator 412 located below. One end of the third feeder 63 is electrically connected to the third connection terminal of the combiner 43, and the core end of the other end is electrically connected to the feedback point of the first radiator 411 located above, and the ground end of the other end is electrically connected to the feedback point of the second radiator 412 located above.

[0059] It should be noted that RF connector 2 serves as the connection port between the antenna and external RF equipment. When the external RF equipment transmits a signal, the signal is input to the first feeder 61 through RF connector 2. The first feeder 61 transmits the signal to the first connection terminal of the combiner 43 inside the liner 42, realizing the access of the signal from the external device to the internal combiner of the antenna. After the signal enters the combiner 43 from the first connection terminal, it will be distributed to the second connection terminal and the third connection terminal according to its internal circuit design. The second feeder 62 transmits the signal distributed by the second connection terminal of the combiner 43 to the lower... The radiator unit 41 and the third feed line 63 transmit the signal distributed by the third connection terminal of the combiner 43 to the radiator unit 41 located above. When current flows into the first radiator 411 and the second radiator 412 above and below through the second feed line 62 and the third feed line 63 respectively, according to the law of electromagnetic induction, the current flowing on the radiator will generate a changing magnetic field, which will then excite electromagnetic waves to radiate into space. Due to the structure and positional relationship of the upper and lower radiator units, the electromagnetic waves radiated by them will superimpose and interfere with each other in space, and together form the overall radiation field of the antenna.

[0060] This embodiment also includes a second feeder assembly 7, which includes a fourth feeder 71, a fifth feeder 72, and a sixth feeder 73. One end of the fourth feeder 71 is electrically connected to another RF connector 2, and the other end extends into the lower liner 42, passes around the choke 5, extends into the upper liner 42, and is electrically connected to the first connection end of the corresponding combiner 43. One end of the fifth feeder 72 is electrically connected to the second connection end of the corresponding combiner 43, and the core end of the other end is electrically connected to the feedback point of the first radiator 411 near the choke 5, and the ground end of the other end is electrically connected to the feedback point of the second radiator 412 near the choke 5. One end of the sixth feeder 73 is electrically connected to the third connection end of the corresponding combiner 43, and the core end of the other end is electrically connected to the feedback point of the first radiator 411 near the cap 32, and the ground end of the other end is electrically connected to the feedback point of the second radiator 412 near the cap 32.

[0061] It should be noted that after one end of the fourth feeder 71 is connected to the RF connector 2, it first extends into the lower liner 42, then loops around and passes through the choke 5 to enter the upper liner 42 and connect to the first connection terminal of the combiner 43. The choke 5 has a suppressive effect on signals of a specific frequency. The fourth feeder 71 loops around and passes through it. By utilizing the characteristics of the choke 5, the transmitted signal can be filtered and optimized, reducing the transmission of interference signals, while ensuring that the target signal passes smoothly and reaches the combiner 43. When the signal enters the combiner 43 from the first connection terminal, it will be distributed to the second and third connection terminals according to its internal circuit design. The subsequent connection method is the same as that with the first feeder assembly 6.

[0062] This embodiment also includes a support member 8 and a coil frame 9. The coil frame 9 is disposed inside the housing 31 and close to the whip body seat 13. The side of the coil frame 9 has an outlet hole 91 and an inlet hole 92. The ends of the first feed line 61 and the fourth feed line 71 away from the RF connector 2 extend into the coil frame 9 and pass through the outlet hole 91, surround the coil frame 9 and pass through the inlet hole 92 to extend into the lower liner tube 42. The support member 8 is fixed inside the housing 31 and is located between two adjacent radiator units 41 to fix the positions of the adjacent first radiator 411 and second radiator 412.

[0063] It should be noted that, through the standardized routing of the first feed line 61 and the fourth feed line 71 by the coil frame 9 and the possible electromagnetic shielding effect, the electromagnetic coupling interference between feed lines and the influence of external electromagnetic interference on the signal are effectively reduced. At the same time, the routing method around the coil frame optimizes the signal transmission path, reduces signal loss and distortion during transmission, and improves the accuracy and stability of signal transmission.

[0064] Working principle:

[0065] An external radio frequency (RF) device generates an RF signal, which is input into the antenna through an RF connector 2. After the signal is input from one of the RF connectors 2, it enters the first feeder 61. The first feeder 61 transmits the signal to the first connection terminal of the combiner 43 inside the liner 42. The combiner 43 appropriately distributes the input signal to the second and third connection terminals. The second feeder 62 transmits the signal distributed by the second connection terminal of the combiner 43 to the lower radiator element 41; the third feeder 63 transmits the signal distributed by the third connection terminal of the combiner 43 to the upper radiator element 41.

[0066] The signal input from another RF connector 2 enters the fourth feeder 71. After one end of the fourth feeder 71 is connected to the RF connector 2, it first extends into the lower liner 42, then passes around the choke 5 and enters the upper liner 42 to connect to the first connection terminal of the corresponding combiner 43. The combiner 43 also distributes the signal to the second connection terminal and the third connection terminal. The fifth feeder 72 transmits the signal distributed by the second connection terminal of the combiner 43 to the radiator unit 41 near the choke 5. The sixth feeder 73 transmits the signal distributed by the third connection terminal of the combiner 43 to the radiator unit 41 near the cap 32.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
