Technical Field

[0001] The utility model discloses a directional antenna with a servo device which can be switched to omnidirectional use in the field of wireless communication. The omnidirectional and directional antennas can be switched to use according to user needs, and can also be used in single frequency or multi-frequency. Background Art

[0002] With the rapid development of the communications industry, the form of antennas is also constantly changing. While people pursue high-quality wireless communication to transmit various types of data information, they also need to make the equipment broadband, miniaturized, and conformal to improve the utilization of space. Antennas, as components that radiate and receive electromagnetic waves, are an important part of wireless systems. The quality of antenna performance directly determines the quality of communication in wireless communication systems. Without antennas, it is impossible to establish any radio system. Therefore, in line with the development trend of radio equipment, research on antennas that are more adaptable to application environment requirements is becoming increasingly active and has become an important research branch in the discipline.

[0003] In important communication fields, in order to achieve smooth communication and eliminate interference, multi-band, multi-function radio stations and broadband FM radio stations will be widely used. The FM rate is getting higher and higher, and the FM range is getting wider and wider. The original form of antenna can no longer meet the needs of the current application environment. In addition, multiple frequency band antennas are densely distributed in the same space, and the interference between them is relatively serious, affecting the communication quality. Other optional spaces for placing antennas are also not suitable for the original form of antennas. In order to solve the above contradictions, it is necessary to develop an antenna with a simple structure, small size, simple feeding structure, and directional and omnidirectional conversion. Utility Model Content

[0004] In view of this, the purpose of the present invention is to improve the problem that users need to use both single or multiple frequency omnidirectional antennas and single or multiple frequency directional antennas in the same space.

[0031] Below, the utility model is further described in conjunction with the accompanying drawings.

[0032] A directional antenna with a servo device that can be switched to omnidirectional use, comprising a directional antenna, an antenna bracket, a reflector, a cable assembly, a rotating joint, a servo device, etc.

[0033] The servo equipment consists of a gear plate, a motor, a housing, a power supply and a drive device.

[0034] Screws are fixed on both sides of the directional antenna. Two antenna brackets pass through the screws and are fixed with nuts to support the directional antenna.

[0035] Fix the two antenna brackets to the grooves of the gear plate by screwing them so that the antenna surface points to the center of the gear plate; adjust the pitch angle of the directional antenna by visually observing the angle marking on the side of the directional antenna, and lock the nut between the antenna bracket and the directional antenna; multiple groups of grooves can be set on the gear plate to facilitate the installation and use of multiple directional antennas; if the installation position of the gear plate is limited, the antenna can also be installed in an up and down mode at the same gear plate position.

[0036] One end of the cable assembly is connected to the directional antenna interface, and the other end of the cable assembly is connected to the rotary joint through the cable hole of the gear disk; the cable is fixed to the contact parts on both sides of the gear disk by binding bands.

[0037] The rotating joint is installed on the inner side of the shell just below the center of the gear disk, with the external interface exposed; the external interface is used to transmit directional antenna signals; when the gear disk rotates, the rotating joint can effectively solve the cable entanglement problem of the cable assembly during the rotation. According to the number of directional antennas, multiple cable heads can be connected to the cable assembly of each directional antenna, and then the number of cable heads can be reduced by adding power dividers and other means, and all directional antenna signals can be transmitted through the rotating joint, so that multiple directional antennas can be connected and used at the same time.

[0038] The reflector is made of metal, placed in the center of the gear disk, and is concentric with the gear disk and detachable. It is used to reflect the signal emitted by the directional antenna, and the external signal is reflected to the directional antenna through the reflector.

[0039] The servo device drives the motor to rotate by supplying power, and the motor drives the gear plate to rotate through its own pinion; the rotation direction is controlled by the driving device, so that the gear plate can complete forward and reverse movement; the gear plate is marked with angle markings, and the directional antenna can be rotated to a specified angle for use according to actual applications.

[0040] When used in the form of a directional antenna, in case one, the gear disc frame is set with a directional antenna, the mouth faces the center of the gear disc, the gear disc does not rotate or rotates to the user-specified position, and the reflector is used to reflect the signal; in case two, the gear disc frame is set with a directional antenna, the mouth faces away from the center of the gear disc, the gear disc does not rotate or rotates to the user-specified position; in case three, multiple directional antennas with different frequency ranges can be set up on the gear disc, and the signal is switched according to the frequency of use, and the signal is transmitted through the rotating joint. The use process is the same as in case one and case two. In case four, directional antennas of different frequencies are connected to a broadband power divider, and the total signal is transferred to the user through the rotating joint, which can meet the user's broadband use environment, and the use process is the same as in case one and case two.

[0041] When used in the form of an omnidirectional antenna, in case 1, a small number of directional antennas are installed on the gear disk, with the mouth facing the center of the gear disk, and the signal is reflected by the reflector. The gear disk rotates forward or reversely, and the signal is based on the center of the gear disk. There are directional antennas reflecting the reflector in all horizontal directions or receiving the signal from the other party, which is similar to the application scenario of omnidirectional antennas. If necessary, the number of directional antennas can be increased to enhance the characteristics of omnidirectional antennas; in case 2, a small number of directional antennas are installed on the gear disk, with the mouth facing away from the center of the gear disk, and directly radiate or receive signals. The gear disk rotates forward or reversely, and the signal is based on the center of the gear disk. There are directional antennas in all horizontal directions that continuously output or receive signals from the other party, which is similar to the application scenario of omnidirectional antennas. If necessary, the number of directional antennas can be increased to enhance the characteristics of omnidirectional antennas; if the number of directional antennas with multiple angles on the gear disk reaches a certain number, all directional antennas work at the same time, and the gear disk can be used without rotating. Case 3: Directional antennas of different frequencies are connected to broadband power dividers, and the total signal is transferred to users after passing through the rotating joint, which can meet the user's broadband omnidirectional antenna usage environment. The use process is the same as case 1 and case 2.

[0042] The advantage of using omnidirectional antennas is that, taking multiple directional antennas in two frequency ranges as an example, the multiple directional antennas in one frequency range have their apertures facing away from the center of the gear disk, directly radiating or receiving signals, and the multiple directional antennas in another frequency range have their apertures pointing toward the center of the gear disk, using reflectors to reflect signals. All directional antennas rotate forward or reverse through the gear disk, and the signals are based on the center of the gear disk. Directional antenna signals in two frequency ranges are continuously output or received from each other in all horizontal directions.

[0043] The directional antenna can be used with the mouth pointed toward or away from the center of the gear plate according to user habits; or the directional antenna can be installed in the same position of the gear plate and used in an upper and lower installation form. The purpose of this design is to facilitate the use of multiple frequency omnidirectional antennas in a limited space. If the signal is transmitted with the antenna on the aircraft, the shape of the reflector can be modified to change the reflection angle of the reflector or adjust the radiation angle of the antenna to increase the angle of the maximum gain of the omnidirectional radiation, which is convenient for signal transmission with the aerial antenna.

[0044] If necessary, a radome can be added to protect the antenna, power supply and servo equipment.

[0045] It can be placed on a platform for use, or it can be equipped with a tripod and other auxiliary support equipment to facilitate the use of the antenna.

[0046] A small number of directional antennas can perform the functions of omnidirectional antennas, and their performance is equivalent to that of multiple directional antennas at various angles in the horizontal plane, which reduces costs and has significant effects.

If the number of directional antennas at multiple angles on the gear disk reaches a certain number, all directional antennas work at the same time and the gear disk can be used without rotating.
