Abstract
The utility model aims to provide a laser formed stacked GPS (global positioning system) antenna, which comprises a mobile phone housing and an antenna body. The mobile phone housing is made of laser activated modified plastics, the antenna body is in a stacked structure and disposed on the mobile phone housing, and the antenna body is formed on the mobile phone housing by means of the LDS (laser direct structuring) technology. Focused beams are projected to a part, required for making the antenna body, of the mobile phone housing which is made of the laser activated modified plastics, the part of the mobile phone housing is then reacted to separate out metallic oxide, and electroless plating copper is then performed, so that high manufacturing precision of the antenna is guaranteed, and process flow is simplified. Further, the antenna body is stacked technically, a pattern of the antenna body is carved out on a stacked base, and thereby the overall size of an antenna module is reduced while the length of the antenna body is guaranteed, and the purpose of the utility model is achieved.
Description
Technical field
The utility model relates to a kind of gps antenna, particularly a kind of multilayer gps antenna of laser formation.
Background technology
GPS is exactly by accepting satellite-signal, the terminal that positions or navigate.And received signal just must be used antenna.Gps satellite signal is divided into L1 and L2, and frequency is respectively 1575.42MHZ and 1228MHZ, and wherein, L1 is open civil signal, and signal is a Circular Polarisation, and signal strength signal intensity is about 166-DBM, belongs to more weak signal.These characteristics have determined and will prepare special antenna for the reception of gps signal.
Existing gps antenna is divided into perpendicular polarization and Circular Polarisation from polarization mode, and with present technology, the effect of perpendicular polarization is less than Circular Polarisation, and therefore except special circumstances, gps antenna all can adopt Circular Polarisation; And gps antenna is divided into built-in aerial and external antenna from the modes of emplacement.
Present most gps antenna is the right-hand polarization ceramic dielectric, and its part is: ceramic antenna, low noise signaling module, cable, joint.
In existing mobile phone, generally adopt an extra plastic cement antenna holder and an antenna to fix, and then the plastic rubber bracket that will be provided with antenna is solidly connected with the handset shell spiral shell that is provided with the PCB motherboard, thereby finishes being communicated with of antenna and PCB motherboard; The antenna structure of this mobile phone needs earlier antenna to be installed on the plastic rubber bracket, and then plastic rubber bracket and the handset shell that is provided with the PCB mainboard are assembled, and has increased the difficulty of assembling widely, has reduced the qualification rate of assembling simultaneously.Because plastic rubber bracket need carry out die sinking separately, therefore strengthened the cost of material and use mould in addition.
In sum, at the defective of prior art, need a kind of multilayer gps antenna of laser formation especially, to solve above-mentioned problem.
The utility model content
The purpose of this utility model is to provide a kind of multilayer gps antenna of laser formation, solve the defective of above-mentioned prior art, contoured beam antenna on handset shell, antenna adopts sandwich construction, under the prerequisite of the length that guarantees antenna, reduce the overall dimensions of antenna effectively.
The technical problem that the utility model solved can realize by the following technical solutions:
A kind of multilayer gps antenna of laser formation is characterized in that, but it comprises handset shell and the antenna body of being made by the laser activation modified plastics, and described antenna body is a sandwich construction, and described antenna body is arranged on the described handset shell.
In an embodiment of the present utility model, interconnect between every layer the described antenna body.
In an embodiment of the present utility model, the surface of described antenna body is provided with chemical plating copper layer.
In an embodiment of the present utility model, the described antenna body of one deck is at interval the shape of square-wave waveform closely at least.
Further, the described 0.3mm that is spaced apart.
In an embodiment of the present utility model, the described antenna body of one deck is elongated at least, and the length of described antenna body is 13mm, and width is 1mm.
The multilayer gps antenna of laser formation of the present utility model, antenna body adopts the moulding on handset shell of LDS technology, but handset shell is made for the laser activation modified plastics, focused beam is incident upon the part that needs to make antenna body on the handset shell, the handset shell of this part is reacted, the precipitating metal oxide, and then by chemical plating copper facing, guarantee the high accuracy that antenna is made, and technological process is simplified, and antenna body adopts multilayer technique simultaneously, and radium undercuts the pattern of antenna body on multi-layer substrate, under the prerequisite of the length that guarantees antenna body, reduce the overall dimensions of Anneta module, realize the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained to be well understood to.
