Description

Technical Field

[0001] The utility model relates to the technical field of miniature base station antenna auxiliary equipment, in particular to an antenna for a miniature base station. Background Art

[0002] The basic principle of antennas is that when alternating current flows on a wire, electromagnetic radiation is generated, thereby transmitting signals through electromagnetic radiation. Existing micro base station antennas mostly use "plate antennas", which are shaped like a plate and are usually installed outdoors at high places and mostly on poles. Plate antennas are directional antennas, with the plate facing the coverage direction and tilted downward at a certain angle.

[0003] However, since the plate-shaped antennas of micro base stations are mostly installed at outdoor high places such as rooftops and building roofs, their installation posture is easily affected by the weather, and the existing pole installation equipment for plate-shaped antennas mainly relies on the clamping force between the clamp and the column to maintain the stability of the antenna. If the bolts of the clamp are loose, the antenna may slide down along the column. And when the antenna is affected by lateral wind, the antenna will also rotate axially along the column, causing the antenna's plate surface to change in the coverage direction. Therefore, those skilled in the art hereby propose a technical solution for a micro base station antenna to solve this problem. Utility Model Content

[0029] A plurality of grooves 23 are provided in an annular array on the outer surface of the convex ring 22, and a circle of annular grooves 211 coupled with the convex ring 22 are provided on the inner surface of the clamp 210. The width of the annular groove 211 is 2 / 3 of the width of the clamp 210, and the depth of the annular groove 211 is adapted to the thickness of the convex ring 22. A plurality of convex strips are arranged and fixed in an annular array on the inner cavity side wall of the annular groove 211, and the convex strips and the grooves 23 are coupled to each other.

[0030] The clamp 210 is annular in shape as a whole, and locking bolts 24 are provided at both ends of the clamp 210. A sleeve 26 is fixed to the end of the L-shaped connecting rod 29 away from the clamp 210, and the sleeve 26 is fixed to the outer ring surface of the double-headed screw 25.
