Description

Technical Field

[0001] The utility model belongs to the technical field of antenna equipment, in particular to a six-port horizontal large-angle spotlight antenna. Background Art

[0002] A spotlight antenna is an antenna used in wireless communication systems, primarily to enhance signal coverage and quality. It is usually mounted on the top or side of a building and looks similar to a traditional lighting fixture, hence the name "spotlight antenna". This antenna is designed to be more visually concealed while providing good wireless signal coverage.

[0003] During the use of the antenna, the frequency band of the antenna is usually 1710-2690 / 3300-3700MHz, and it can be used for multiple 4G and 5G communication systems at the same time (1710-2690MHz for 4G communication, 3300-3700MHz for 5G communication). Although two types of oscillators are used, respectively in the 4G and 5G frequency bands, the frequency band of the antenna is very wide, and the oscillator is easy to resonate in another frequency band, resulting in poor isolation between different frequency bands.

[0004] There are two ways to improve the isolation difference in the prior art. One is to add a cavity filter, and the other is to increase the spacing between different frequency bands, which requires increasing the size of the antenna. Both methods require a lot of cost.

[0005] To this end, the utility model provides a six-port horizontal large-angle spotlight antenna. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the utility model describes a six-port horizontal large-angle spotlight antenna, comprising a reflector; three low-frequency dual-polarization vibrators are installed on the reflector, and the low-frequency dual-polarization vibrators are regularly arranged in a longitudinal linear array on the reflector; the low-frequency dual-polarization vibrators are arranged at a position corresponding to the middle of the reflector; eight high-frequency dual-polarization vibrators are installed on the reflector, and every four high-frequency dual-polarization vibrators are regularly arranged in a longitudinal linear array to form two groups; the two groups of high-frequency dual-polarization vibrators are symmetrically arranged along the center line of the reflector, and by directly designing the filter on the power divider, in the 4G communication frequency band, a separate microstrip filter design is adopted, and after the vibrator is connected to the power divider, the structural design of connecting to the microstrip filter through a coaxial cable achieves the function of reducing material costs, reducing processes, and reducing labor costs.

[0008] The frequency band of the low-frequency dual-polarization vibrator is between 1710 and 2690 MHz; the frequency band of the high-frequency dual-polarization vibrator is between 3300 and 3700 MHz. By setting two dual-polarization vibrators with different frequency bands, 4G and 5G communications can be guaranteed at the same time. At the same time, the dual-polarization vibrator antenna has the advantages of being able to cover a wider frequency range and simultaneously transmit ±45° polarized signals, thereby improving the capacity and reliability of the communication system, high gain and high efficiency, simple structure, low cost, easy production, low profile and low intermodulation.

[0009] The low-frequency dual-polarization vibrator and the high-frequency dual-polarization vibrator can be fixed to the reflection plate by bolts, which makes the installation of the vibrators more convenient.

[0010] The low-frequency dual-polarization vibrator and the high-frequency dual-polarization vibrator are both arranged on the radiation surface of the reflector. Installing the vibrator on the radiation surface of the reflector can focus and direct the radiation, while suppressing the reverse radiation and improving the antenna performance. It can also provide additional structural support for the reflector, making the antenna more durable and facilitating the integration and maintenance of the antenna.

[0011] The arrangement directions of the low-frequency dual-polarization vibrator and the high-frequency dual-polarization vibrator are arranged in parallel. By arranging the low-frequency dual-polarization vibrator and the high-frequency dual-polarization vibrator in a regular pattern, the radiation mode and beam shape of the antenna can be more effectively controlled, thereby improving the gain and directivity of the antenna, reducing energy scattering and loss, and reducing mutual interference between antennas and coupling effects between adjacent vibrators. It can also provide a more uniform coverage range, especially in indoor environments, which helps to reduce signal blind spots and ensure that users can obtain stable signal strength at any location.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model describes a six-port horizontal large-angle spotlight antenna, which directly designs the filter on the power divider. In the 4G communication frequency band, a separate microstrip filter is designed. After the vibrator is connected to the power divider, the structural design is connected to the microstrip filter through a coaxial cable. This realizes the function of reducing material costs, reducing processes, and reducing labor costs. It effectively solves the problem that there are two ways to improve the isolation difference in the prior art, one is to increase the cavity filter, and the other is to increase the spacing between different frequency bands. In this way, the antenna size must be increased. Both methods require increasing more costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Specific examples are given below.

[0020] like Figure 1 to Figure 2 As shown, a six-port horizontal large-angle spotlight antenna described in an embodiment of the utility model includes a reflector 1; three low-frequency dual-polarization vibrators 2 are installed on the reflector 1, and the low-frequency dual-polarization vibrators 2 are arranged in a longitudinal linear array on the reflector 1; the low-frequency dual-polarization vibrators 2 are arranged at a position corresponding to the middle of the reflector 1; eight high-frequency dual-polarization vibrators 3 are installed on the reflector 1, and every four high-frequency dual-polarization vibrators 3 are arranged in a longitudinal linear array to form two groups; the two groups of high-frequency dual-polarization vibrators 3 are symmetrically arranged along the center line of the reflector 1; when working, three low-frequency dual-polarization vibrators 2 of 1710-2690MHz are set to meet the requirements of a large horizontal angle of the radiation lobe, and eight high-frequency dual-polarization vibrators 3 of 3300-3700MHz frequency band are set, and four high-frequency dual-polarization vibrators 3 Arranged vertically to form two groups, the demand for a large horizontal angle of the radiation lobe can be met. At the same time, the three groups of vibrators can be used for one 4G and two 5G communication systems. At the same time, the utility model designs the filter directly on the power divider in the 5G communication frequency band, which can not only reduce material costs, but also reduce processes and labor costs. At the same time, designing the filter directly on the power divider will increase the lateral size of the power divider. Due to the small size of the antenna, if the design method of the 5G communication frequency band is adopted, other costs will increase (such as lengthening the cable, increasing the base plate, etc.). The utility model adopts a separate microstrip filter design method in the 4G communication frequency band. After the vibrator is connected to the power divider, it is connected to the microstrip filter through a coaxial cable (4G has only one group of vibrators and 5G has two groups of vibrators. This is also the reason for deciding to use a separate microstrip filter in the 4G frequency band to reduce costs).

[0021] The frequency band of the low-frequency dual-polarization vibrator 2 is between 1710 and 2690 MHz; the frequency band of the high-frequency dual-polarization vibrator 3 is between 3300 and 3700 MHz. By setting two dual-polarization vibrators with different frequency bands, 4G and 5G communications can be guaranteed at the same time. At the same time, the dual-polarization vibrator antenna can cover a wider frequency range and can simultaneously transmit signals of ±45° polarization, thereby improving the capacity and reliability of the communication system, high gain and high efficiency, simple structure, low cost, easy production, low profile and low intermodulation.

[0022] The low-frequency dual-polarization vibrator 2 and the high-frequency dual-polarization vibrator 3 can be fixed on the reflection plate 1 by bolts, which makes the installation of the vibrators more convenient.

[0023] The low-frequency dual-polarization vibrator 2 and the high-frequency dual-polarization vibrator 3 are both arranged on the radiation surface of the reflector 1. Installing the vibrator on the radiation surface of the reflector 1 can focus and direct the radiation, while suppressing the reverse radiation and improving the antenna performance. It can also provide additional structural support for the reflector 1, making the antenna more durable and facilitating the integration and maintenance of the antenna.

[0024] The arrangement directions of the low-frequency dual-polarization vibrator 2 and the high-frequency dual-polarization vibrator 3 are arranged in parallel. By arranging the low-frequency dual-polarization vibrator 2 and the high-frequency dual-polarization vibrator 3 in a regular pattern, the radiation mode and beam shape of the antenna can be more effectively controlled, thereby improving the gain and directivity of the antenna, reducing energy scattering and loss, and reducing mutual interference between antennas and coupling effects between adjacent vibrators. It can also provide a more uniform coverage range, especially in indoor environments, which helps to reduce signal blind spots and ensure that users can obtain stable signal strength at any location.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
