Abstract
The invention provides an antenna manufactured by insert injection molding, and a method for manufacturing the antenna by insert injection molding. Through arranging a heat-insulating protective layer between a first plastic layer and a second plastic layer of an antenna manufactured by LDS and LEP technologies, when the second plastic layer is molded, the heat-insulating protective layer effectively insulates heat and blocks part of impact forces, so that the first plastic layer is protected from being softened or molten when the second plastic layer is molded, and an antenna metal layer is prevented from being damaged. A glue layer is added between the heat-insulating protective layer and the second plastic layer, so as to improve bonding effect of the heat-insulating protective layer and the second plastic layer. The heat-insulating protective layer can be arranged in a multi-layer structure according to practical application scenarios of the antenna, for example, arranging a hardening layer, a shock resistance layer, and a temperature resistance layer, and application occasions of the antenna are effectively enlarged. The antenna structure effectively reduces material restriction on the material of the first layer, so as to reduce cost of the antenna structure. The antenna is very beneficial for popularization of the LDS and LEP technologies.
