Problems solved by technology
The omnidirectional ceiling antenna of the prior art generally includes a radome, a radiator, a ground plate, a bottom plate, a connecting screw, a mounting nut and cables; the radiator and the ground plate are composed of multiple materials, and are fixed by rivets or other parts , the production process is cumbersome, the production efficiency is low, and the antenna intermodulation index cannot guarantee consistency
At the same time, after the cable of the omnidirectional ceiling antenna in the prior art passes through the connecting screw and is welded to the radiator, the end of the cable lacks protection, and the cable shakes seriously, which affects the intermodulation index of the antenna.
Moreover, the installation order of the omnidirectional ceiling antenna in the prior art is limited, and the installation method is single, which is not conducive to the use in modern multi-scenario and complex environments

The invention provides a broadband low-intermodulation omni-directional ceiling antenna which includes a radome, a radiator, a bottom plate, a connecting screw, a mounting bolt, and a cable. The antenna is characterized in that a mounting nut plate and a plunger are arranged; the radiator is a shell integrally made of a metal material, square slots are uniformly distributed on the shell, and the same number of grounding pieces as the slots are distributed around the shell; the cable passes through the plunger, the connecting screw and the bottom plate, and after the plunger is in threaded connection with the lower end of the connecting screw, the cable is fixed through partial structure deformation of the plunger; and the mounting nut plate is mounted outside the connecting screw, and is open. Compared with the prior art, provided with the integrally formed radiator, the plunger with a fastening function and the open mounting nut plate, the broadband low-intermodulation omni-directional ceiling antenna of the invention has the advantages of wide band, low standing wave and low intermodulation, and meets the requirement of indoor broadband coverage for the LTE technology.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a broadband low-intermodulation omnidirectional ceiling-absorbing antenna used in an indoor distribution system. Background technique [0002] With the continuous development of communication technology, more requirements are put forward for antenna products, especially the requirements for frequency band and intermodulation value are getting higher and higher. The omnidirectional ceiling antenna of the prior art generally includes a radome, a radiator, a ground plate, a bottom plate, a connecting screw, a mounting nut and cables; the radiator and the ground plate are composed of multiple materials, and are fixed by rivets or other parts , the production process is cumbersome, the production efficiency is low, and the consistency of the antenna intermodulation index cannot be guaranteed. At the same time, after the cable of the omnidirectional ceiling antenna in the prior art...
