Description

Technical Field

[0001] This application relates to the technical field of satellite antennas, and in particular to a mast antenna with an integrated backfeed feed unit. Background Technology

[0002] 5G network is the fifth generation of mobile communication network. During the construction process, the antenna needs to be fixed with the pole using mounting parts. The waist-shaped hanging plate is horizontally attached to one side of the pole, and then the clamps are used to hinge the waist-shaped hanging plate to both sides and pass through the pole to fix it in the middle position. Then the antenna is installed on the outside of the hanging plate.

[0003] Commonly known satellite antennas typically include a reflector, a bracket, and an extension rod. The reflector is connected to the bracket, and the extension rod extends from the bracket toward the front of the reflector. In this known technology, the extension rod is prone to interference with the reflector during retraction. After the end user assembles the satellite antenna, the connection between the reflector and the antenna rod can become unstable, causing the reflector to wobble and thus affecting signal reception. Utility Model Content

[0004] To address the aforementioned technical issues, this application provides a mast antenna with an integrated back-feed feed unit.

[0005] This application provides a mast antenna with an integrated back-feed feed unit, employing the following technical solution:

[0006] A mast antenna with a rear-feed integrated feed unit includes a mast assembly, an angle adjustment assembly, an integrated feed unit, and a reflector. The angle adjustment assembly is connected to the mast assembly and fixed to the antenna mast. The integrated feed unit is detachably connected to the angle adjustment assembly and its angle can be adjusted by the angle adjustment assembly. The integrated feed unit is detachably connected to the bottom of the reflector. The mast assembly has a slot, and the angle adjustment assembly has a fixing hole. Positioning bolt assemblies for fixing the two are inserted into the slot and the fixing hole. A reinforcing rod is detachably connected to the angle adjustment assembly next to the positioning bolt assembly, and a reinforcing bolt assembly for fixing the two is provided between the reinforcing rod and the positioning bolt assembly.

[0007] By adopting the above technical solution, a strip groove is set on the mast assembly, so that the positioning bolt assembly does not need to be adapted to the hole diameter, making it easier to fix the mast assembly and the angle adjustment assembly to each other; at the same time, the reinforcing rod can further stabilize the fixing of the positioning bolt assembly when the connection is unstable, thereby improving safety performance and signal stability.

[0008] Preferably, the feedhorn integrated unit includes a feedhorn housing, inside which are arranged a duplexer, a satellite modem module, a satellite encryption module, a satellite control module, a power supply module, and a WIFI module; the WIFI module is located at the edge of the feedhorn housing, and a WIFI external antenna is arranged on the feedhorn housing at the position corresponding to the WIFI module.

[0009] Preferably, the duplexer includes a duplexer bracket, a connecting flange on the duplexer bracket and fixed to the feed box body by the connecting flange, a filter and a power amplifier are respectively provided at both ends of the duplexer bracket, and a low noise amplifier is connected to the filter.

[0010] Preferably, a receiving antenna is fixedly connected to the dual-position bracket, and the receiving antenna passes through the reflector to receive satellite signals.

[0011] Preferably, a vent valve is provided on the side of the feed box.

[0012] By adopting the above technical solution and using the ventilation valve, the heat inside the box can be dissipated through the ventilation valve, while maintaining a consistent pressure inside and outside the feed box. This prevents the problem of high-temperature gas generated by internal electronic components during operation from being difficult to dissipate, and can effectively improve the service life of the product.

[0013] Preferably, the mast assembly includes a mast bracket, on which multiple positioning rods are provided. The multiple positioning rods are divided into two groups and respectively abut against both sides of the antenna mast. A positioning plate is provided between the outer ends of the positioning rods. The positioning rods pass through the positioning plate and the outer ends of the positioning rods are threadedly connected to an adjusting bolt assembly that can drive the positioning plate closer to the mast bracket.

[0014] By adopting the above technical solution, multiple positioning rods are set to abut against both sides of the antenna mast, and then fixed by the positioning plate. By rotating the adjusting bolt assembly, the positioning plate and the mast bracket can be tightly abutted against the antenna mast, thereby achieving stable fixation of the entire device.

[0015] Preferably, the opposing surfaces of the mast bracket and the positioning plate are provided with U-shaped slots, and the mast bracket and the positioning plate are attached to the antenna mast through the U-shaped slots.

[0016] By adopting the above technical solution and setting a U-shaped slot, the contact surface between the mast bracket and the positioning plate and the antenna mast is larger, thereby achieving a more stable fixation of the mast bracket to the antenna mast.

[0017] Preferably, the angle adjustment component includes a connecting frame, which is detachably connected to the pole support. The connecting frame has an arc-shaped groove, and a connecting rod is provided on the feed box body at a position corresponding to the arc-shaped groove. The connecting rod is inserted into the arc-shaped groove and fixed by a connecting bolt assembly.

[0018] By adopting the above technical solution, a connecting rod is set on the feed box. The connecting rod is inserted into the arc groove and then fixed by the connecting bolt assembly. When necessary, the position of the connecting rod in the arc groove can be adjusted, thereby adjusting the relative position of the feed box and the relative angle of the feed box, making the operation simpler and more convenient.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] By setting multiple positioning rods to abut against both sides of the antenna mast, and then fixing them with positioning plates, the positioning plates and mast brackets can be tightly pressed against the antenna mast by rotating the adjusting bolt assembly, thereby achieving stable fixation of the entire device.

[0021] The groove on the pole assembly eliminates the need for the positioning bolt assembly to be fitted with a suitable hole diameter, making it easier to fix the pole assembly and the angle adjustment assembly together. At the same time, the reinforcing rod can further stabilize the connection of the positioning bolt assembly if it is unstable, thus improving safety performance. Attached Figure Description
