Street lamp structure with built-in antenna

Abstract

The invention discloses a street lamp structure with a built-in antenna, and the structure comprises a lamp cap and a lamp holder; a lamp post is connected between the lamp cap and the lamp holder; the lamp post also serves as an antenna body, and an omnidirectional antenna is arranged in the antenna body; the lamp holder is fixed to a cement foundation through foundation bolts, and a wiring pipeis arranged in the cement foundation. The omnidirectional antenna comprises a dielectric substrate, and a plurality of groups of radiation units are arranged on the dielectric substrate, wherein any radiation unit comprises a first radiation arm arranged on the front surface of the dielectric substrate and a second radiation arm arranged on the back surface of the dielectric substrate, the first radiation arm and the second radiation arm are symmetrically arranged up and down, and a feed device connected with a cable device is arranged between the first radiation arm and the second radiation arm. According to the invention, signal coverage of the frequency band of 806-960 MHz can be achieved while normal lighting is met; meanwhile, the advantages of good concealment, small size, light weight and low cost are achieved, and panic of community residents to the electromagnetic environment can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of lighting and wireless communication, and in particular relates to a built-in antenna type street lamp structure. Background technique [0002] With the continuous development of all walks of life and the increasing pace of urban construction, it is often difficult for base station signals to be completely covered in cities with many high-rise buildings. Outdoor distributed antennas are used as transfer stations for base station signals, which can effectively monitor complex environments. Full coverage. [0003] The traditional base station signal relay reception is either a directional antenna installed on the wall or a low-gain omnidirectional antenna. The coverage effect is not very ideal. Therefore, if a high-gain, omnidirectional coverage and low-cost antenna can be provided , will be adopted by major operators. [0004] Based on this, this case provides a street lamp structure with a built-in anten...
