Technical Field

[0001] This utility model relates to the technical field, and in particular to a U-band high-gain magnetoelectric dipole broadband antenna. Background Technology

[0002] Due to their excellent radiation characteristics, magnetoelectric dipole antennas are widely used in base station equipment. With the rapid development of communication technology, the requirements for high performance, low profile, and miniaturization of magnetoelectric dipole antennas have become increasingly stringent. In existing technologies, to reduce the profile of magnetoelectric dipole antennas, folded magnetic dipoles are generally used to reduce their profile height, or dielectric loading is employed to reduce the profile height. However, this also results in a complex structure for the magnetoelectric dipole antenna, increasing the difficulty of integrating the antenna with the back-end circuitry. Utility Model Content

[0003] The purpose of this invention is to provide a U-band high-gain magnetoelectric dipole broadband antenna, which solves the problem of complex structure of existing magnetoelectric dipole antennas.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A U-band high-gain magnetoelectric dipole broadband antenna includes a reflector and a mounting plate. The mounting plate is mounted above the reflector via multiple support columns. An electric dipole and a magnetic dipole are mounted on the mounting plate, with the electric dipole and the magnetic dipole positioned opposite each other and spaced apart on the reflector. A first dielectric module and a second dielectric module are mounted on the electric dipole, and a third dielectric module and two spaced-apart low-loss dielectric modules are mounted on the magnetic dipole. The antenna also includes a conductor mounted on the mounting plate. One end of the conductor is sequentially embedded in the first dielectric module and the second dielectric module, with a first clamping block on the second dielectric module to press the end of the conductor. The other end of the conductor is sequentially embedded in the third dielectric module and the two low-loss dielectric modules, with second clamping blocks on the two low-loss dielectric modules to press the end of the conductor. A connection socket for connecting the magnetic dipole is mounted on the reflector.

[0007] Preferably, the magnetic dipole oscillator includes an integrally bent second inclined plate, a second bent plate, and a second vertical plate. The width of the second inclined plate gradually narrows from one end of the fixed plate to one end of the second bent plate. The third dielectric module is mounted on the second bent plate, and two low-loss dielectric modules are spaced apart on the second vertical plate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] See Figures 1-2 As shown in the figure, an embodiment of this utility model proposes a U-band high-gain magnetoelectric dipole broadband antenna, including a reflector 1 and a fixed plate 2. The fixed plate 2 is mounted above the reflector 1 by multiple support columns 3. The support columns 3 achieve the spaced installation of the fixed plate 2 and the reflector 1, forming an overall frame structure to ensure structural strength. Simultaneously, an electric dipole 4 and a magnetic dipole 5 are mounted on the fixed plate 2. The electric dipole 4 and the magnetic dipole 5 are arranged opposite to each other and spaced apart on the reflector 1. By spaced apart and oppositely arranged between the fixed plate 2 and the reflector 1, the antenna achieves its intended function. A first dielectric module 6 and a second dielectric module 7 are installed on the electric dipole resonator 4, and a third dielectric module 8 and two spaced-apart low-loss dielectric modules 9 are installed on the magnetic dipole resonator 5. The system also includes a conductor, such as a feeder, mounted on the fixing plate 2. One end of the conductor is sequentially embedded in the first dielectric module 6 and the second dielectric module 7, with a first pressure block 10 on the second dielectric module 7 to press the end of the conductor. The other end of the conductor is sequentially embedded in the third dielectric module 8 and the two low-loss dielectric modules 9, with second pressure blocks 11 on the two low-loss dielectric modules 9 to press the end of the conductor. This ensures reliable installation and fixation of the magnetic dipole resonator 5 and the electric dipole resonator 4, arranges the internal signal flow conductors, and satisfies the relative isolation between the magnetic dipole resonator 5 and the electric dipole resonator 4. A connection socket 12 for connecting the magnetic dipole resonator 5 is installed on the reflector plate 1, enabling external connections such as power supplies and signal sources.

[0021] Magnetoelectric dipoles can achieve strong coupling between electric and magnetic fields through structural design, thereby generating efficient electromagnetic radiation at specific frequencies. Combining the characteristics of electric and magnetic dipoles, magnetoelectric dipoles can simultaneously generate both electric and magnetic field radiation. Furthermore, a feeder is integrated into the magnetic dipole element 5 for excitation. By simplifying the structure, both the magnetic dipole element 5 and the electric dipole element 4 are integrated, meeting low profile requirements and providing outdoor wind resistance.

[0022] Specifically, the electric dipole oscillator 4 includes a first inclined plate 41, a first bent plate 42, and a first vertical plate 43, all integrally bent. The width of the first inclined plate 41 gradually narrows from one end of the fixed plate 2 to one end of the first bent plate 42. The first dielectric module 6 is mounted on the first bent plate 42, and the second dielectric module 7 is mounted on the first vertical plate 43. The entire electric dipole oscillator 4 is an integrally formed structure. The contact surface between the oscillator and the air medium is achieved through bending, and the extension length of the electric dipole oscillator 4 is increased while the interval between the fixed plate 2 and the reflector 1 is fixed.

[0023] Meanwhile, the magnetic dipole oscillator 5 includes an integrally bent second inclined plate 51, a second bent plate 52, and a second vertical plate 53. The width of the second inclined plate 51 gradually narrows from one end of the fixed plate 2 to one end of the second bent plate 52. The third dielectric module 8 is mounted on the second bent plate 52, and two low-loss dielectric modules 9 are spaced apart on the second vertical plate 53, which also increases the contact surface between the magnetic dipole oscillator 5 and the air medium. In addition, the spacing between the first bent plate 42 and the second bent plate 52 can determine the spacing between the entire electric dipole oscillator 4 and the magnetic dipole oscillator 5. Specifically, a spacer block 17 is installed on the fixed plate 2. The two ends of the spacer block 17 abut against the electric dipole oscillator 4 and the magnetic dipole oscillator 5, respectively. The spacer block 17 determines the spacing between the first bent plate 42 and the second bent plate 52.

[0024] Specifically, the two low-loss dielectric modules 9 are symmetrically arranged, and the width of the low-loss dielectric modules 9 gradually narrows from top to bottom. Generally, they are used to press and limit the feeder, and the limiting is achieved on both sides according to the structure of the feeder.

[0025] Specifically, a connecting pin 13 and a dielectric sleeve 14 sleeved on the connecting pin 13 are fixed to the magnetic dipole oscillator 5. The connecting pin 13 is connected to the inner core of the connecting socket 12 and is connected to the feed line of the magnetic dipole oscillator 5.

[0026] Furthermore, the upper end of the support column 3 is provided with a first flange 15, and the lower end of the support column 3 is provided with a second flange 16. The first flange 15 is installed on the fixing plate 2, and the second flange 16 is installed on the reflector plate 1. The fixing plate 2 and the reflector plate 1 are connected by the first flange 15 and the second flange 16, which can ensure that the edge position will not be deformed after fastening.
