Antenna radiation body made of low-melting-point metal or metal alloy, and manufacturing method

Abstract

The invention relates to the field of wireless communication technology, in particular to an antenna radiation body made of low-melting-point metal or metal alloy, and a manufacturing method therefor. The manufacturing method for the antenna radiation body made of low-melting-point metal or metal alloy comprises the following steps: (1), a plastic bracket is formed through injection moulding, and a plurality of grooves are formed on the plastic bracket; and (2), molten low-melting-point metal or metal alloy is injected into the grooves of the plastic bracket, and after solidification, the antenna radiation body is made. Compared with the prior art, the manufacture method for the antenna radiation body made of low-melting-point metal or metal alloy material has the advantages that deformation and melting to the plastic bracket can not be caused, and a thinner antenna radiation body can be manufactured; and meanwhile, the electric conductivity is excellent, and the performance of the antenna is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an antenna radiator made of metal or metal alloy with a melting point lower than 300° C. and a manufacturing method thereof. Background technique [0002] At present, antennas are generally used to receive signals on mobile terminal products. Commonly used antennas include: metal shrapnel antennas, flexible circuit board antennas, electroless plating or electroplating antennas, and wire-wound antennas. These commonly used antenna radiators are usually made of conventional metal materials, such as copper alloy, stainless steel, gold, aluminum alloy, zinc alloy and other metal materials with a melting point higher than 300°C. However, these processes have the following drawbacks: [0003] Among the current conventional products, due to the light and thin development and structural characteristics of mobile terminal products, most antenna products are three-dimension...
