Preferably, the fixation hole is at least one.
Preferably, the metallic antenna layer includes copper plate and nickel coating, and the copper plate is set under nickel coating
Side.
Preferably, the thickness of coated copper layer range is 6-12UM, and the nickel plating layer thick range is 2-4UM.
The beneficial effect of LDS antenna disclosed by the utility model is: antenna is activated antenna holder surface laser is radium-shine
Slot, chemical plating wants metallic antenna layer in antenna slot, and antenna holder is made to have LDS antenna function.It is also opened up on antenna holder
Ground slot, metallic antenna layer extend to ground slot inner wall and bottom surface, and metallic ground diaphragm one end is connect with ground slot, metallic ground
Diaphragm is in contact with the metallic antenna layer in ground slot, realizes the connection of metallic ground diaphragm and LDS antenna, has LDS antenna
There is ground structure.And metallic ground diaphragm and ground slot are attached by fixing piece, more convenient metallic ground diaphragm with connect
Geosyncline is attached, while people also being facilitated to replace or safeguard metallic ground diaphragm.Metallic ground diaphragm and ground slot
Area, ground slot can be opened up out by pre-set area, by fixing piece can preferably by metallic ground diaphragm with
Ground slot is fixed, it is not necessary to occupy biggish LDS antenna area, reduce the contact surface of metallic ground diaphragm Yu LDS antenna
Product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model LDS antenna；
Fig. 2 is the cross-sectional view in the utility model LDS antenna diagram 1 at A-A.
Specific embodiment
The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below: LDS- laser
Straight forming technology is referred to and directly circuit pattern is transferred on moulded plastic original part surface using digital control laser, utilizes solid
The three-dimensional surface of workpiece forms the technology of circuit interworking architecture.
Fig. 1 and Fig. 2, a kind of LDS antenna, including antenna holder 10 and metallic ground diaphragm 30 are please referred to, on antenna holder
Offer the mounting hole 11 for installing LDS antenna, the day for the LDS antenna that 10 surface of antenna holder is activated by laser
Wire casing, antenna holder 10 activate ground slot 12 by laser along side, and antenna slot connects with ground slot 12, antenna slot internalization
Be coated with metallic antenna layer 20, and metallic antenna layer 20 includes copper plate 21 and nickel coating 22, and copper plate 21 is set on nickel coating 22
Side makes antenna holder 10 have LDS antenna function, and the production for carrying out antenna using LDS technology is more convenient to be designed antenna
And processing, while the volume of antenna is also saved, more spaces are provided, and more convenient people are designed row to antenna
Cloth designs more reasonable antenna.
