In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are a subset of the embodiments in the present application and not all embodiments in the present application. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Example one

Referring to fig. 1 and fig. 2, a first embodiment of the present application provides a communication antenna 100, which includes a pole 110, a reflection plate 120, and a plurality of radiating elements 130, where the reflection plate 120 includes a first surface 121 and a second surface 122 that are disposed opposite to each other, and the plurality of radiating elements 130 are arranged on the first surface 121 of the reflection plate 120 along a horizontal direction; the reflective plate 120 is mounted to the pole 110 by a second face 122.

It should be noted that the reflective plate 120 is a metal thin plate, the holding pole 110 is cylindrical, and there are two mounting manners of the reflective plate 120 on the holding pole 110, one is that the reflective plate 120 is fixedly mounted on the holding pole 110 through the second surface 122, and the other is that the reflective plate 120 is movably mounted on the holding pole 110 through the second surface 122. Specifically, whether the reflection plate 120 is movably mounted or fixedly mounted on the pole 110 needs to be flexibly selected according to the height of the mounting position of the communication antenna 100 in practical application. Here, the shape of the pole 110 is not limited to the cylindrical shape, and may be another shape that facilitates fixing of the reflection plate 120 thereto. The plurality of radiating elements 130 are arranged on the first surface 121 along the horizontal direction, which means that the plurality of radiating elements 130 are arranged on the first surface 121 along the vertical direction, and the purpose of the arrangement is to expand the lobe width of the radiating elements 130 in the vertical direction, so that the communication antenna 100 can also be applied to buildings with dense crowds in the vertical direction.

Among them, there are four implementations regarding the arrangement of the plurality of radiating elements 130:

as a first implementation manner, the plurality of radiating elements 130 are arranged in a single row, and the single row of radiating elements 130 are radiating elements 130 with the same frequency band.

It should be noted that, when the plurality of radiation elements 130 are arranged in a single row along the same direction, the larger the number of radiation elements 130 is, the better theoretically, because the energy concentration of the communication antenna 100 for signals is realized by increasing the number of radiation elements 130, and the larger the number of radiation elements 130 is, the higher the concentration degree of energy is, the larger the gain is, but the communication antenna 100 with high gain is usually long and heavy. Therefore, in order to ensure that the shape of the communication antenna 100 is not too large and avoid inconvenience caused by an excessive volume during the installation process, the number of the radiating elements 130 is generally controlled to 6 to 8, and generally not more than 10. When a single row of radiating elements 130 is a radiating element 130 with the same frequency band, for example, the radiating elements 130 are all set to 900M (890-960MHz) frequency band, so that when the communication antenna 100 does not need to have a certain range of frequency for use, it is not necessary to select a plurality of radiating elements 130 mixed in different frequency bands, thereby simplifying the structural design of the communication antenna 100, where the frequency band of GSM900 refers to: 890MHz to 960MHz, wherein the uplink is 890MHz to 915MHz, and the downlink is 935MHz to 960 MHz.

It should be added that in the Communication field, the frequency band refers to the frequency range of electromagnetic waves and has a unit of Hz, wherein the frequency band used in the GSM (Global System for Mobile Communication, abbreviated as GSM), which is the 2G second generation Mobile Communication System, is the frequency band used at the beginning, is GSM900MHz, and as the line pressure increases with the increase of the number of people, the frequency band such as 1800MHz is expanded for decompression. With the development of mobile communication systems and the emergence of 3G and 4G networks, the frequency band originally used for GSM is also gradually applied to the 3G and 4G networks. Therefore, the 900M/1800M bands listed here are independent of the specific network system, and are only a frequency range, and the corresponding antenna can also be applied to the 3G/4G network of the corresponding band, such as UMTS (Universal Mobile Telecommunications system, i.e. 3G third generation Mobile communications system) 900M, LTE (Long Term Evolution, i.e. 4G fourth generation Mobile communications system) 900M, LTE1800M, and so on. The 5G network has a high frequency range (2100M, 3500M, etc.), but the principle is the same, and the antenna can also be applied to the 5G network as long as the radiating elements of the corresponding frequency band are used.

As a second implementation manner, the plurality of radiating elements 130 are arranged in a single row, and the single row of radiating elements 130 is radiating elements 130 with different frequency bands, and the frequency band of the radiating elements 130 arranged near the edge of the arrangement is greater than the frequency band of the radiating elements 130 arranged near the center of the arrangement.

It should be noted that, a plurality of radiating elements 130 arranged in a single row are set as radiating elements 130 with different frequency bands, and the frequency band of the radiating element 130 close to the edge of the arrangement is greater than the frequency band of the radiating element 130 arranged close to the center of the arrangement, mainly because the size of the external shape of the radiating element 130 is related to the size of the frequency band of the radiating element 130. In general, the larger the frequency band of the radiating element 130, the smaller the volume thereof, so to ensure that the overall structure of the communication antenna 100 is smaller, the frequency band of the radiating element 130 near the edge of the arrangement is set to be smaller than the frequency band of the radiating element 130 near the center of the arrangement, that is, the radiating element 130 with a larger outline is set at the periphery of the arrangement, and the radiating element 130 with a smaller outline is set inside the arrangement, that is, the higher the frequency band of the radiating element 130 is, the smaller the size thereof is; whereas the lower the frequency band of the radiating element 130, the larger the size.

For example, the radiating elements 130 in the 900M (890-.

As a third implementation manner, the plurality of radiating elements 130 are arranged in multiple rows, and the extending directions of the radiating elements 130 in two adjacent rows are parallel to each other. The frequency bands of the radiation elements 130 in two adjacent rows are the same.

As a fourth realizable mode, the plurality of radiating elements 130 are arranged in a plurality of rows, and the extending directions of the radiating elements 130 in two adjacent rows are parallel to each other. The frequency bands of the radiation elements 130 in two adjacent rows are different.

It should be noted that the plurality of radiation elements 130 are arranged in a plurality of rows, and the extending directions of the radiation elements 130 in two adjacent rows are parallel to each other, which is the same as the above-mentioned function. The only difference is that, compared with the case where the two adjacent rows of radiating elements 130 are radiating elements 130 with the same frequency band, the two adjacent rows of radiating elements 130 are arranged to be radiating elements 130 with different frequency bands, so that the frequency range to which the communication antenna 100 is applied in the actual application process may not be limited to a specific frequency, and thus the arrangement enables the communication antenna 100 to have a wider frequency range and higher flexibility. Illustratively, the radiation elements 130 of the 1800M (1710-. Because the radiation oscillator is of a metal sheet structure, the larger the frequency range is, the smaller the metal sheet appearance of the radiation oscillator is, for example, the appearance of the radiation oscillator in the 900M (890-. Therefore, in the installation, the radiation elements 130 having a slightly larger outer shape are arranged on the outer periphery of the array, and the radiation elements 130 having a slightly smaller outer shape are arranged inside the array. For example, the radiating elements 130 in the 900M (890-.

Referring to fig. 3, in one implementation, communication antenna 100 further includes a feed network 140 and a feed interface 150, and radiating element 130 is coupled to feed interface 150 via feed network 140.

It should be noted that the feeder interface 150 is mainly used for transmitting the electrical signal transmitted by the device transceiver through the feeder to the radiation element 130, and transmitting the electromagnetic wave signal received by the radiation element 130 from the outside to the device transceiver. The feeding network 140 is a network circuit structure formed by connecting wires, and is mainly used for transmitting and distributing electrical signals from the feeding line interface 150, so that the electrical signals sent by the device are transmitted and distributed to each radiation oscillator 130, and then converted into electromagnetic wave signals to be transmitted to the space.

Regarding the communication antenna 100, there are two implementation manners, it should be noted that the communication antenna 100 in this embodiment is specifically a plate-shaped antenna, wherein the plate-shaped antenna can be divided into a mechanical plate-shaped antenna and an electrical tilt plate-shaped antenna according to the adjustment manner:

as a first implementation, the communication antenna 100 is a mechanical plate antenna, as shown in fig. 3.

It should be noted that, when the communication antenna 100 is a mechanical plate-shaped antenna, the manner of receiving the electromagnetic wave signal from the outside is completely the same as that described above, that is, the received external electromagnetic wave signal is transmitted to the feeding network 140 through the feeding line interface 150 and is converted, distributed and transmitted, and therefore, in this case, the structure of the communication antenna 100 is simple and easy to implement.

As a second implementation manner, referring to fig. 4, the communication antenna 100 is an electrically tunable planar antenna, and the feeding network 140 is provided with a phase shifter 141.

When the communication antenna 100 is an electrically tunable patch antenna, the phase shifter 141 is disposed on the feed network 140, and the phase shifter 141 is controlled to adjust the phase of the electromagnetic wave on the feed network 140 so as to meet the usage requirement of the electromagnetic wave beam tilt angle of the communication antenna 100, mainly in order to adapt to the structure of the electrically tunable patch antenna.

The installation method between the reflection plate 120 and the derrick 110 includes the following two implementation methods:

as a first implementation manner, the communication antenna 100 further includes a hoop 160, and the pole 110 is fixedly mounted on the second surface 122 through the hoop 160.

The pole 110 is fixed to the second surface 122 of the reflector 120 by the hoop 160, which is suitable for the case where the angle of the communication antenna 100 does not need to be adjusted after installation. Because the hoop 160 has simple structure and light volume, the fixing in this way can greatly simplify the installation process and save the installation cost.

As a second implementation, communication antenna 100 further includes an antenna arm (not shown), and mast 110 is movably mounted on second surface 122 via the antenna arm.

It should be noted that, the pole 110 is movably mounted on the second surface 122 of the reflection plate 120 through the antenna arm, which is suitable for the case that the mounting angle of the communication antenna 100 needs to be adjusted continuously according to the use requirement after the mounting. Compared with the case that the pole 110 is installed on the second surface 122 of the reflection plate 120 through the hoop 160, the installation angle of the communication antenna 100 can be flexibly adjusted in this way, so that the flexibility is higher and the use is more convenient. The structure of the antenna arm is the prior art, and therefore the implementation is not described in detail herein.

Example two

In a second aspect, referring to fig. 1 and 2, the present application further provides a communication antenna apparatus, including an antenna housing 200, a bracket 300, and the communication antenna 100 described in the foregoing embodiments, wherein the antenna housing 200 is disposed on the bracket 300; the communication antenna 100 is fixed in the antenna housing 200, and the feeder interface 150 of the communication antenna 100 is provided on the antenna housing 200.

The antenna cover 200 is disposed outside the reflector 120, and on one hand, it can protect the reflector 120 and the radiator 130 inside, and prevent foreign objects from falling into the antenna cover or damaging the internal structure due to environmental erosion, and on the other hand, it can beautify the appearance of the communication antenna 100, so that the communication antenna will not be accepted by people due to the excessively abrupt structure when being installed on a city building.

The installation method of the feeder interface 150 includes the following two implementation methods:

as a first realisation, the feeder interface 150 is provided at the bottom of the antenna housing 200, the feeder interface 150 being cylindrical.

It should be noted that, when the feeder interface 150 is disposed at the bottom of the antenna housing 200, that is, the antenna housing 200 is disposed above the feeder interface 150, and thus the antenna housing 200 has a protection effect on the feeder interface 150, that is, the antenna housing 200 has a protection effect on the feeder in the feeder interface 150, at this time, the feeder interface 150 is disposed in a cylindrical shape, and the installation direction thereof is along the vertical direction, which can simplify the structural design of the feeder interface 150 and facilitate the access of the feeder in the feeder network 140.

As a second realizable approach, the feed line interface 150 is disposed at a sidewall of the antenna housing 200, and the feed line interface 150 is L-shaped.

It should be noted that, when the feeder interface 150 is disposed on a side wall of the antenna housing 200, that is, the antenna housing 200 is disposed on a side of the feeder interface 150, so that the antenna housing 200 cannot protect the feeder interface 150, that is, the antenna housing 200 cannot protect the feeder in the feeder interface 150, and therefore, in order to protect the feeder in the feeder interface 150, the feeder interface 150 needs to be disposed in an L shape, and when the antenna housing is installed, an opening of the L-shaped feeder interface 150 needs to face downward to protect the feeder therein from water and foreign matters.

In an implementation manner, the communication antenna apparatus further includes a radio frequency unit fixing frame 400, and the radio frequency unit fixing frame is disposed on the bracket 300.

It should be noted that, a radio frequency unit fixing frame 400 is further disposed on the bracket 300 of the communication antenna apparatus, and the radio frequency unit fixing frame 400 is mainly used to facilitate installation of other devices in the communication base station.

In an implementation manner, the bracket 300 includes a first bracket 310 and a second bracket 320 that are connected to each other, the first bracket 310 and the second bracket 320 have an included angle therebetween, the first bracket 310 extends in a vertical direction, and the second bracket 320 is disposed in an inclined manner; the antenna cover 200 is disposed at the junction of the first bracket 310 and the second bracket 320.

It should be noted that the bracket 300 is configured to include two brackets, that is, the first bracket 310 and the second bracket 320, and an included angle is formed between the two brackets, and the included angle ranges from 30 ° to 60 °, for example, the included angle may be any angle between 30 °, 40 °, 50 °, and 60 °, or between 30 ° and 60 °, which is not limited in this embodiment. This is mainly provided to form a triangular structure between the first leg 310, the second leg 320, and the antenna housing 200. The triangular structure formed by disposing the antenna housing 200 at the junction of the first bracket 310 and the second bracket 320 is more reliable and stable due to the stability of the triangle.

In addition, it should be noted that, in order to enable the communication antenna device to be better integrated with the surrounding urban environment, the antenna housing 200 and the bracket 300 may be optimized in shape and structure, for example, the antenna housing 200 and the bracket 300 may be configured to be similar to a solar water heater, that is, the antenna housing 200 is cylindrical and is similar to a water storage tank of the solar water heater, and the bracket 300 is similar to a heat collection pipe bracket of the solar water heater. Compared with the common structure, the antenna housing 200 and the bracket 300 are designed to be similar to the shape of a solar water heater, and on the first hand, the antenna housing 200 similar to the shape of a water storage tank of the solar water heater can protect the communication antenna 100 inside; in the second aspect, the bracket 300 similar to the heat collecting tube bracket of the solar water heater can make the whole structure of the communication antenna device more stable; in a third aspect, the antenna housing 200 and the antenna housing of the bracket 300 are shaped like a solar water heater, so that the antenna housing can beautify the appearance of the communication antenna device, the communication antenna device can better integrate with the life and working environment of people, the trouble caused to people after the communication antenna device is installed can be reduced, and the communication antenna device can be better accepted by people. The shapes of the antenna housing 200 and the bracket 300 are not limited to the shape imitating solar energy, and may be flexibly set according to the beautification requirement in the actual use process, which is not limited in this embodiment.
