Abstract

The invention relates to an antenna oscillator and a manufacturing method thereof and particularly relates to an antenna oscillator utilizing plastic as a main material and a manufacturing method of the antenna oscillator. The antenna oscillator is characterized in that a main body is a plastic body which is formed by injection molding and has the structure and size of the antenna oscillator; a copper coating with the thickness of 3-25mu m is electroplated on the external surface of the plastic body; and a silver coating or tin coating with the thickness of 2-20mu m is electroplated on the copper coating. The manufacturing method comprises injection molding, electroplating and welding. According to the invention, the plastic is used for replacing steel, the plastic oscillator is electroplated and welded at a low temperature, and then is installed in an antenna; in all tests, the original aluminum oscillator standards can be achieved; and the manufacturing cost and the whole mass of the antenna are greatly lowered.

Description

technical field [0001] The invention relates to an antenna vibrator and a manufacturing method thereof, in particular to an antenna vibrator using plastic as a main material and a manufacturing method thereof. Background technique [0002] The antenna vibrator (hereinafter referred to as the vibrator) is a component on the antenna. The full name is the antenna vibrator, which has the function of guiding and amplifying electromagnetic waves, so that the electromagnetic signal received by the antenna is stronger. The vibrator is made of metal with good conductivity, generally copper (Cu), aluminum (Al), silver (Ag), etc., and tin (Sn) or silver (Ag) is often plated for soldering needs. Some vibrators are rod-shaped, and some have more complex structures. Generally, many vibrators are arranged in parallel on the antenna. [0003] At present, the vibrators are all made of metal. The main problems faced by vibrators made of metal are that they are expensive and heavy, which brin...
