Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please refer to Fig. 1 to Fig. 3, the manufacture method of the Anneta module that the embodiment of the present invention provides, comprises the following steps:
Hardware is provided;
Making antenna body 10, carries out punch forming to obtain antenna body 10 according to antenna pattern to described hardware;
There is provided injection molding machine and for the first plastic mold in described injection molding machine and described second plastic mold, the shape and size of described first plastic mold and described second plastic mold and described antenna body 10 adapt,
First time injection molding, described antenna body 10 to be positioned in described first plastic mold and first time injection mo(u)lding carried out to described antenna body 10, obtaining semi-finished product;
Described semi-finished product to be positioned in described second plastic mold and to carry out second time injection mo(u)lding to described antenna body 10 by second time injection molding.
The manufacture method of the Anneta module that the embodiment of the present invention provides utilizes Sheet Metal Forming Technology to obtain antenna body 10, and utilizes twice encapsulate injection mo(u)lding to be subject to reliable protection with the size and dimension of the hardware structure guaranteeing antenna body 10, guarantees antenna performance.This guard method is simple, can avoiding using oversize antenna to improve gain, reducing portability and the ease of use of whole terminal equipment; And ensure that the miniaturization of antenna simultaneously, reduce overall size, provide cost savings.
In this embodiment, with the antenna body 10 formed hardware, there is stable form and fixing structure by first time injection mo(u)lding, play preliminary protection and constitutionally stable object; By second time injection mo(u)lding to protect antenna body 10 and to fix, obtain modular antenna structure.
In this embodiment, described injection mo(u)lding can be completed by twice or above injection moulding process, and the number of times of its injection mo(u)lding does not limit, for the purpose of the described antenna body 10 that adequately protects.
Please refer to Fig. 1 and Fig. 2, further, the material of described antenna body 10 is laminar hardware.
Please refer to Fig. 1 to Fig. 3, further, in the step of making antenna body 10, described antenna body 10 comprises radiant body 12 and two signal pins 14 along the outstanding extension of described radiant body 12.Preferably, two described signal pins 14 are respectively the loop connecting pin that the Signal transmissions pin that is connected to signal mainboard and signal carry out ground connection.
The antenna that the embodiment of the present invention provides is processed by the manufacture method of above-mentioned Anneta module, described antenna comprises by the stamping forming antenna body 10 of hardware and the package casing 20 by injection mo(u)lding, and described antenna body 10 comprises and is wrapped in radiant body 12 in described package casing 20 and extends along described radiant body 12 is outstanding and extend out to two signal pins 14 outside described package casing 20.
