Problems solved by technology

Under such circumstances, the problems of heavy weight, high cost and complicated installation of metal (metal die-casting / aluminum stamping) materials in the past have become very prominent, and the industry has begun to pay attention to the feasibility of plastic vibrators as a mainstream solution.
At the same time, with the sharp increase in the frequency band of 5G applications, under the trend of high frequency, high speed, large capacity and miniaturization, the performance requirements of related materials have undergone subversive changes, such as surface metallization, dimensional stability, and high heat resistance. , the balance of good dielectric properties, processability and mechanical properties has great technical challenges, resulting in no mature enough solutions.

Abstract

The invention provides a manufacturing method of an antenna oscillator. The manufacturing method comprises the step of designing and manufacturing the antenna oscillator by adopting the combination of powder spraying and a laser direct structuring process, wherein the oscillator element is made of metal, then the laser direct forming plastic is adsorbed on the base material on the surface of the oscillator element in a powder spraying mode, and a coating is formed. Therefore, various complex fine array circuit designs can be realized on the surface of the antenna oscillator, a conductive circuit is formed after laser activation and chemical plating, and meanwhile, good adhesive force is formed between a plating layer and a base material. Aiming at the development trend of 5G high frequency, high speed, large capacity and miniaturization, the problems in structural design and performance balance when metal or plastic is singly adopted in the field of 5G antenna oscillators can be solved through innovative combination of the two processes.

Description

Technical field [0001] The present invention belongs to the composite material and communication technology, and in particular to a method and product of a 5 g of antenna vibrator. Background technique [0002] Antenna vibrator is a radiation unit for amplifying and receiving electromagnetic waves, one of the key components of an antenna structure. In the field of the antenna, different manufacturers of design, production process, material and radiation efficiency are very different, and the corresponding electrical performance and cost is very different. In the 4G era, the basic type of antenna vibrator is usually divided into two categories of half-wave vibrators and patch vibrators. Among them, half-wave vibrators are the most mature product applications and are currently generally used. The material of conventional half-wave antenna vibrator is mainly metal, and its disadvantages are complex assembly, high cost, and large weight. Relatively, the patch antenna vibrator has the...
