Description

Technical Field

[0001] The utility model relates to the technical field of antennas, and in particular to a new structure of a base plate-shaped antenna. Background Art

[0002] Antennas are an indispensable component of mobile communications and play a very important role. They are located between the transceiver and the electromagnetic wave propagation space, and realize effective energy transfer between the two. By designing the radiation characteristics of the antenna, the spatial distribution of electromagnetic energy can be controlled, resource utilization can be improved, and network quality can be optimized. This is especially important for LTE mobile communication technology, which is the mainstream technology for the transition from 3G to 4G.

[0003] At present, the frequency range of digital communication system DCS is 1710~1880MHz, the frequency range of PHS is 1850~1990MHz, the frequency range of UMTS is 1920~2170MHz, the frequency range of 3G is 1880~2200MHz, and the frequency range of WLAN is 2400~2500MHz. However, the traditional fiberglass antenna can only cover the high frequency band of 1710~2170MHz in a directional manner or the low frequency band of 800~960MHz. With the widespread application of new technology standards such as 3G, LTE, and WAN, the traditional fiberglass antenna has poor omnidirectional coverage and can no longer meet the requirements of mobile communication network construction.

[0017] The present invention is further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0018] Please refer to Figure 1 , Figure 2 and Figure 3A novel structure of a base plate antenna includes a shell, a pole clamp 3 for fixing the shell is provided on the back of the shell, the pole clamp 3 is fixedly connected to the shell through a connecting plate 9, a reflector 7 is provided inside the shell, a high-frequency vibrator 12, an intermediate-frequency vibrator 10 and a low-frequency vibrator 11 are provided on the surface of the reflector 7, the intermediate-frequency vibrator 10, the low-frequency vibrator 11 and the high-frequency vibrator 12 are combined through a power splitter board combiner to form a port, and two intermediate-frequency vibrators 10 are combined through a one-to-two power splitter board 13, and three high-frequency vibrators 12 are combined through a one-to-three power splitter board, and the one-to-two power splitter board 13 and the one-to-three power splitter board 15 are respectively passed through the dual-frequency combiner 16 and the three-frequency combiner 14 through the lead wires to pass through the shell.

[0019] The antenna can be fixed on a columnar object, such as a telephone pole, by means of the pole clamp 3 on the back of the shell, and a reflector 7 is provided inside the shell, on the surface of which a high-frequency vibrator 12, a medium-frequency vibrator 10 and a low-frequency vibrator 11 are provided. Different vibrators correspond to different electromagnetic signals, so that the antenna has the characteristics of broadband, good omnidirectional uniformity, simple structure and strong anti-interference. The entire antenna has the characteristics of broadband and multi-frequency during use, so as to avoid the problem of poor omnidirectional coverage of traditional antennas.

[0020] The shell is provided with a wire outlet, and a wire sheath 4 can be inserted into the wire outlet, and a feeder 5 is passed through the wire sheath 4, and a connector 6 is provided at the end of the feeder 5.

[0021] The feeder 5 is specifically a copper RG141 cable, and the connector 6 uses an SMA-J connector. The vibrator connection cable generally uses an RG086 cable to connect and combine with each other, but when the power of the application equipment is relatively large, an RG141 cable is generally used to connect and combine with each other. These two types of cables are respectively adapted to various equipment and application environments, that is, to ensure stable signal output, good coverage performance, and compatibility with equipment. The lead feeder 5 is located at the lower end of the outer cover 1 and is connected to the connector SMA-J connector. The feeder 5 is specifically a high-temperature resistant RG141 cable, and is exposed 200mm when the feeder 5 is connected to the power splitter combiner.

[0022] In the above scheme, the low-frequency oscillator 11 is specifically a 806-960MHz oscillator, the medium-frequency oscillator 10 is specifically a 1710-2700MHz oscillator, and the high-frequency oscillator 12 is specifically a 3300-3600MHz oscillator. Therefore, the entire antenna has the characteristics of broadband and multi-frequency during use.

[0023] The shell includes an outer cover 1 and a cover plate 2, the outer cover 1 and the cover plate 2 are fixedly connected by bolts, and the connection between the lower ends of the outer cover 1 and the cover plate 2 is also filled with universal glue to enhance the structural strength between the outer cover 1 and the cover plate 2. The high-frequency vibrator 12, the intermediate-frequency vibrator 10 and the low-frequency vibrator 11 are arranged on the side of the reflecting plate 7 close to the outer cover 1, and the low-frequency vibrator 11 and the power splitter board combiner are fixed on the reflecting plate 7 by nylon.

[0024] All the dipole feed sources are installed on the front side of the reflector 7, and the back side of the reflector 7 is used to fix the corresponding power splitter board, thereby saving space and compressing the overall volume of the antenna.

[0025] The pole clamp 33 is fixedly connected to the connecting plate 9 inside the cover plate 2 by bolts. After the connecting plate 9 and the cover plate 22 are locked, glue is applied around to prevent water from seeping into the antenna. The pole clamp 33 can be adjusted by the connecting plate 9 bolts. After the antenna is assembled, it is connected to the external device through the pole clamp 33 and the connector 6. Therefore, the installation of the entire antenna becomes convenient and easy, which is conducive to the installation and use of the antenna.

[0026] The utility model provides a novel structure of a base plate antenna. The antenna can be fixed on a columnar object, such as a telephone pole, by a pole clamp on the back of a shell, and a reflector is provided inside the shell. A high-frequency vibrator, a medium-frequency vibrator and a low-frequency vibrator are provided on the surface of the reflector. Different vibrators correspond to different electromagnetic signals, so that the antenna has the characteristics of broadband, good omnidirectional uniformity, simple structure and strong anti-interference. The whole antenna has the characteristics of broadband and multi-frequency during use, so as to avoid the problem of poor omnidirectional coverage of traditional antennas.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
