As shown in fig. 1, the present embodiment provides an antenna 1, which includes an antenna body and a radome, wherein the antenna body is independently packaged in the radome, and the antenna body realizes conversion between a wired signal and a wireless signal by radiating or receiving an electromagnetic wave to or from a space. The beam width of the electromagnetic wave radiated by the antenna 1 determines the lobe width of the antenna 1, and the lobe width of the antenna 1 refers to the angle at which the fan formed by the electromagnetic wave radiated by the antenna 1 is opened. It should be noted that the lobe width of the antenna 1 is a characteristic parameter of the antenna 1, i.e. a specific engineering parameter of the antenna 1, and is a parameter with a fixed value of the antenna 1.

In general, the antenna 1 is fixed on the holding pole 2 through the antenna bracket 3, and the holding pole 2 is fixed on the top of a building or a steel tower, so as to reduce the influence of ground buildings on electromagnetic wave reflection.

Through the arrangement, when the antenna 1 is installed, the device 4 for measuring the coverage area of the antenna is covered on the antenna cover, and because the included angle between the light beams emitted by the first light beam emitter 45 and the second light beam emitter 46 on the device is the same as the lobe width of the antenna 1, the light beams emitted by the first light beam emitter 45 and the second light beam emitter 46 can be used for simulating the boundary of the electromagnetic wave radiated by the antenna 1, the area between the two light beams is the coverage area of the electromagnetic wave radiated by the antenna 1, and therefore, a constructor can accurately judge the coverage area of the antenna 1 through the light beams. In the installation, when constructor adjusted the angle of antenna 1, the direction of beam transmission changed, and constructor constantly adjusted antenna 1 until the light beam can cover the target area, also is that the electromagnetic wave of antenna 1 covers the target area, is favorable to avoiding like this with the overlapping range coincidence of adjacent antenna 1 for antenna 1's coverage is effectual.

In the installation process, the emitting direction of the light beams is adjusted by rotating the first indicating arm 43 and the second indicating arm 44, and then the included angle between the two light beams can be adjusted, so that the included angle between the two light beams is the same as the lobe width of the antenna 1. Thus, compared with the first beam emitter 45 and the second beam emitter 46 which are clamped on the base 41, the device can change the included angle between the two beams, so that the device can be suitable for antennas 1 with different lobe widths, and the device can be universal.

Wherein the first light beam emitter 45 can be clipped on the end of the free end of the hollow first indicating arm 43, and the second light beam emitter 46 can be clipped on the end of the free end of the hollow second indicating arm 44. Moreover, by arranging the beam emitter at the free end of the indicating arm, the irradiation position of the beam can be extended, so that the constructor can observe the coverage of the beam more clearly and intuitively.

In one example, the device 4 for measuring the coverage area of the antenna further includes a mounting piece and a locking device, the mounting piece is connected with the base 41, the mounting piece extends outwards along a direction departing from the base 41, and an arc-shaped slideway is arranged on the mounting piece; first instruction arm 43 and second instruction arm 44 are all articulated with base 41 through the articulated shaft, and the axis perpendicular to of articulated shaft instructs the central line of arm, is equipped with first slider on the first instruction arm 43, is equipped with the second slider on the second instruction arm 44, and first slider and second slider are all slided and are established in the arc slide.

Preferably, the angle indicating dial 42 is formed with graduation lines, and the first indicating arm 43 is configured with a first alignment line along the axis thereof, and the first alignment line is used for indicating the angle of the axis of the first indicating arm 43 on the angle indicating dial 42; the second indicating arm 44 is provided with a second alignment line along its axis for indicating the angle of the axis of the second indicating arm 44 on the angle indicating plate 42.

The first alignment line and the second alignment line can be formed by marking on the surface of the indicating arm by a construction worker through a marking pen, and can also be formed by cutting the indicating arm through a thermal cutting device.

Illustratively, the angle indicator 42 may have a semicircular shape, the center of the semicircular angle indicator 42 is located on the base 41, and the linear end of the semicircular angle indicator 42 is connected to the base 41. The term "connected" is to be understood broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

For example, the scale lines on the angle indicating dial 42 may be set to 0 to 180 degrees, and the minimum scale value is 1 degree. Wherein, the 0 degree scale mark and the 180 degree scale mark extend reversely with the center of the circle of the angle indicating dial 42 as the midpoint.

For another example, the graduation marks on the angle indicating dial 42 may be set to graduation marks of +90 degrees to-90 degrees, and the minimum graduation value is 1 degree. Further, a zero scale line is located in the middle of the angle indicating dial 42, and the +90 degree scale line and the-90 degree scale line extend in opposite directions with the center of the angle indicating dial 42 as the midpoint.

For example, when the lobe width of the antenna 1 is 60 degrees, the first alignment line is aligned with the +30 degree graduation mark, and the second alignment line is aligned with the-30 degree graduation mark.

Further, the device 4 for measuring the coverage of the antenna also comprises a third light beam emitter 47 arranged on the angle indicator disk 42, the light beam emitted by the third light beam emitter 47 being collinear with the zero graduation mark. That is, the third light beam emitter 47 is disposed at the position of the zero scale line of the angle indicating dial 42, and the light beam emitted from the third light beam emitter 47 is emitted in a direction away from the center of the angle indicating dial 42. With such an arrangement, on one hand, a constructor can know the coverage direction of the antenna 1 according to the direction mapped by the light beam emitted by the third light beam emitter 47, and on the other hand, the light beam emitted by the third light beam emitter 47 is positioned in the middle of the light beam emitted by the first light beam emitter 45 and the light beam emitted by the second light beam emitter 46, so that the light beam emitted by the third light beam emitter 47 can be aligned to the middle position of the target area in the installation process, and the target area can be easily covered by the emitted light beam.

In addition to the above embodiments, the first light beam emitter 45, the second light beam emitter 46 and the third light beam emitter 47 may be laser light emitters, or the light emitted by the first light beam emitter 45, the second light beam emitter 46 and the third light beam emitter 47 may be infrared light. Therefore, the penetrating power of the light beam emitted by the light beam emitter is high, and even if the antenna 1 is installed in poor weather, constructors can observe the light beam, so that the device can effectively assist constructors to install. Of course, the light beams emitted by the first light beam emitter 45, the second light beam emitter 46 and the third light beam emitter 47 may be a combination of laser light and infrared light, and the embodiment is not limited thereto.

The means 4 for measuring the antenna coverage also comprise, schematically, a compass 48, the compass 48 being arranged at the centre of the angular indicator disk 42. With this arrangement, the constructor can read the physical azimuth angle of the zero scale line of the angle indicator 42 by using the compass 48, and the physical azimuth angle corresponding to the zero scale line is the horizontal azimuth angle of the antenna 1, so that the constructor can accurately know the horizontal azimuth angle of the antenna 1 adjusted to a proper position.

Specifically, a through hole is formed at the center position of the angle indicating disc 42, the compass 48 can be clamped in the through hole, and the side wall of the compass 48 is adhered to the side wall of the through hole; alternatively, the compass 48 may be bonded to the surface of the angle indicator dial 42 on which the scale lines are formed.

On the basis of the above embodiment, the two ends of the base 41 are respectively provided with the first clamping plate and the second clamping plate, and the first clamping plate and the second clamping plate are used for clamping two opposite sides of the radome. Therefore, the device is clamped on the antenna cover, the connection mode is simple, and the assembly and disassembly are convenient.

In some examples of the present invention, the first clamping plate and the second clamping plate are disposed on the bottom surface of the base 41, and the first clamping plate and the second clamping plate are connected by an elastic member. Therefore, the first clamping plate and the second clamping plate are close to each other towards the middle under the action of the elastic force of the elastic piece so as to further clamp the antenna housing, and the connection between the device and the antenna housing is more reliable; moreover, the first clamping plate and the second clamping plate are convenient to be broken away from the middle so as to disassemble the device. For example, the elastic member is a tension spring, one end of which is connected to a side of the first clamping plate facing the second clamping plate, and the other end of which is connected to a side of the second clamping plate facing the first clamping plate.

Schematically, the device 4 for measuring the coverage of the antenna further comprises a first fixing stud and a second fixing stud, a first threaded hole is formed in the first clamping plate, a second threaded hole is formed in the second clamping plate, the first fixing stud penetrates through the first threaded hole and is used for abutting against one side of the antenna housing, and the second fixing stud penetrates through the second threaded hole and is used for abutting against the other side of the antenna housing. Through the arrangement, the stud is utilized to abut against the antenna housing, so that the clamping plate is prevented from sliding relative to the antenna housing, and the connection relation between the device and the antenna housing is firmer.
