This application claims priority to Chinese Patent Application No. 202210571599.9, filed on May 25, 2022, the content of which is incorporated herein by reference in its entirety.
The present application relates to the technical field of mobile communications, and in particular to a multi-frequency and multi-beam independent electrically adjustable antenna.
With the development of mobile communications, Multiple Input Multiple Output (MIMO) technology requires more and more channels of antenna. During use, at least 4 Transmit 4 Receive (4T4R) (four channels) is required to meet the needs of use. The current single lens antenna can only achieve 2 Transmit 2 Receive (2T2R), and cannot meet the use needs of mobile communications. In addition, the technical solution, like the one described in Chinese Patent Application No. 2020106750469, entitled “Dual Vertically Polarized Multi-beam Antenna with Artificial Dielectric Cylinder”, cannot adjust a beam down tilt angle of an antenna, which is extremely inconvenient to use. In addition, in some current lens antennas, a beam direction is adjusted by moving an oscillator or electromagnetic lens, which causes the position of the oscillator to be shifted relative to the electromagnetic lens, and a signal of the oscillator to change in direction after passing through the electromagnetic lens. In such a structure, the oscillator or electromagnetic lens must be moved as a whole, and an outer shell for mounting the antenna must have enough space for movement. As a result, the size of antenna is large, which is not conducive to installation and carrying. In a process of practical application, it is difficult to precisely control the beam direction of the oscillator by adjusting a beam direction by moving an electromagnetic wave lens or oscillator, and it is also very inconvenient to conduct.
The present application aims to provide a multi-frequency and multi-beam independent electrically adjustable antenna. The multi-frequency and multi-beam independent electrically adjustable antenna has advantages of simple structure, scientific design, small size, flexible setting of beam direction, and being able to meet the requirements of an MIMO technology for the number of channels.

Two ends of the screw 91 of the screw drive mechanism 9 are respectively mounted on a rotating mounting base 30 rotationally. The rotating mounting base 30 is fixed on the mounting plate 3. The screws of the screw drive mechanism for driving the push component D181 to slide relative to the mounting plate 3, the screw drive mechanism for driving the push component D282 to slide relative to the mounting plate 3, the screw drive mechanism for driving the push component D383 to slide relative to the mounting plate 3, the screw drive mechanism for driving the push component D484 to slide relative to the mounting plate 3, the screw drive mechanism for driving the push component D585 to slide relative to the mounting plate 3, and the screw drive mechanism for driving the push component D686 to slide relative to the mounting plate 3 can share two rotating mounting bases 30. Two ends of each of the guide rods 93 of the screw drive mechanism for driving the push component D181 to slide relative to the mounting plate 3, the screw drive mechanism for driving the push component D282 to slide relative to the mounting plate 3, the screw drive mechanism for driving the push component D383 to slide relative to the mounting plate 3, the screw drive mechanism for driving the push component D484 to slide relative to the mounting plate 3, the screw drive mechanism for driving the push component D585 to slide relative to the mounting plate 3, and the screw drive mechanism for driving the push component D686 to slide relative to the mounting plate 3 are also correspondingly mounted on the two rotating mounting bases 30. Each of the push component D181, the push component D282, the push component D383, the push component D484, the push component D585 and the push component D686 is slidably mounted on the mounting plate 3 through four sliding mounting bases 20. A phase shifter is arranged between every two sliding mounting bases 20, so that a sliding sheet of the phase shifter can slide more smoothly when it is pushed. The push component D181, the push component D282, the push component D383, the push component D484, the push component D585 and the push component D686 are all rods, and a sliding hole for the rod to pass through is formed on the sliding mounting base 20.

In order to make the structure of the screw drive mechanism 9 more reasonable, as shown in
As shown in
The clamping component 982 is clamped in the clamping ring groove 9812 of the sheathing component 981, and the locating pin 9821 of the clamping component 982 is inserted through the through hole 9813 of the sheathing component 981 into the pin hole 911 of the screw 91. A first blocking part 912 is arranged on the screw 91, and the sliding block 92 is positioned between the limiting assembly 98 and the first blocking part 912. A second blocking part 9814 is formed on an end face of the sheathing component 981 facing the sliding block 92. A first pressing-against part 923 cooperating with the first blocking part 912 is formed on an end face of the sliding block 92 facing the first blocking part 912, and a second pressing-against part 924 cooperating with the second blocking part 9814 is formed on an end face of the sliding block 92 facing the sheathing component 981. In use, the screw 91 is positively rotated to move the sliding block 92 on the screw 91 closer to the limiting assembly 98, until the second pressing-against part 924 of the sliding block 92 presses against the second blocking part 9814 on the sheathing component 981 and the sliding block 92 stops moving, which can prevent the screw 91 from continuing to rotate to cause the sliding block 92 to lock the screw 91 cooperating with the sheathing component 981. As such, the screw 91 can be prevented from being damaged by excessive torque at the moment when the screw 91 is reversely rotated to move the sliding block 92 farther away from the sheathing component 981. Correspondingly, the screw 91 can be reversely rotated to move the sliding block 92 on the screw 9 closer to the first blocking part 912, until the first pressing-against part 923 of the sliding block 92 presses against the first blocking part 912 and the sliding block 92 stops moving, which allows the sliding block 92 not to separate from the screw 91.
