Abstract

The invention discloses a plastic metallization oscillator unit, which is characterized in that a first supporting column and an oscillator side wall are respectively and directly connected with an antenna metal floor, so that a first metal layer, the first supporting column, the oscillator side wall and the antenna metal floor jointly form a resonant cavity; the formed resonant cavity effectively isolates surface current crosstalk between the oscillators and between the arrays, and the first metal layer, the first supporting column, the second supporting column and the oscillator side wall are the integrally formed plastic metallization substrate, so that the whole plastic substrate can be manufactured in an electroplating manner; the process steps of laser etching, deplating, re-electroplating and the like are avoided, the production cost is greatly reduced, meanwhile, mutual coupling between the arrays is reduced, and the isolation degree between the arrays is improved.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a plastic metallized vibrator unit and communication equipment. Background technique [0002] As the frequency band of the 5G (5th generation mobile networks, fifth-generation mobile communication technology) network moves up, the coverage capability of a single base station is weakened. At the same time, with the rapid growth of 5G user data traffic, the number of base stations and the number of antennas used have increased significantly. Therefore, 5G base stations will adopt Massive MIMO (Multiple Input Multiple Output) array antennas on a large scale. However, a large antenna array usually needs to carry dozens of dipoles, which greatly increases the number of dipoles required. At the same time, with the increase in the size of the 5G base station antenna array, the volume, weight and cost of the entire base station antenna array will also greatly increase. Therefore, the...
