Now communicate.
Fig. 2 schematically illustrates the planar structure schematic diagram of antenna assembly 13.As shown in Fig. 2, antenna assembly 13 includes
Circuit board 133 and shell 12.
Wherein, as shown in Fig. 2, circuit board 133 is equipped with feed 132, feed 132 is for providing pumping signal.Feed 132
It is connected with and connects device 131, connect device 131 for the pumping signal of feed 132 to be transmitted to antenna.Connect device 131
One end is connected with feed 132, and the other end is connected with antenna.Connecting device 131 includes but is not limited to for metallic screw or metal elastic
Piece can also be other conductive components.
As shown in Figures 2 and 3, shell 12 has surface A, and surface A can be appearance or inner surface.Surface A is equipped with
Conductive part 121 and protective layer 122.The conductive energy of conductive part 121, pumping signal are transmitted to shell 12 through conductive part 121.It leads
Electric portion 121 is including but not limited to feed point or grounding point, can also be other conductive components or conductive structure.Protective layer 122 is
One material layer, protective layer 122 cover conductive part 121, are used for conductive part 121 and air exclusion.Conductive part 121 will not as a result,
It can expose and aoxidize in air.The boundary of protective layer 122 can be located within the boundary of surface A, i.e., protective layer 122 is only spread
It is located on part of the surface A；Alternatively, the boundary of protective layer 122 can be laid on entirely with the boundary of aligned surfaces A, i.e. protective layer 122
In surface A.
It is contacted with protective layer 122 as shown in Fig. 2, connecting device 131 and is electrically connected feed 132 with conductive part 121, with
Pumping signal is transmitted to shell 12 by conductive part 121, makes shell 12 as antenna.12 shell of shell is used to be believed according to excitation
Number electromagnetic wave signal is generated, and electromagnetic wave signal is radiate.It should be understood that antenna assembly 13 may include radio circuit and phase
The feed path answered, so that feed 132 is used as exciting signal source, shell 12 is used as antenna.
In the present embodiment, protective layer 122 can be insulating layer (for insulator), be also possible to conductor layer (for conductor).When
When protective layer 122 is insulating layer, connects device 131 and penetrate in insulating layer and (connect device 131 and 12 interior contact of protective layer) simultaneously
It is contacted with conductive part 121, feed 132 is electrically connected with conductive part 121.When protective layer 122 is conductor layer, due to conductor layer
It is connected with conductive part 121, therefore connect device 131 need to only contact with the surface of conductor layer, it can be by feed 132 and conductive part
121 electrical connections.At this point, conductor layer can have excellent oxidation resistance；Or still can be conductive even if being oxidized, to protect
Card connects the good electrical connection properties of device 131 Yu conductor layer.Certainly, connecting device 131 can also penetrate in conductor layer, then with
Conductive part 121 contacts.
The scheme of the present embodiment, by the covered protection layer 122 on the conductive part 121 of shell 12, protective layer 122 will be led
Electric portion 121 and air exclusion, it is therefore prevented that 121 ingress of air of conductive part and aoxidize.When feed 132 is by connecting device 131 and leading
When electric portion 121 is electrically connected, shell 12 carries out signal radiation as antenna.Since protective layer 122 makees the protection of conductive part 121
With conductive part 121 can continue, stablize conduction, to ensure that the radiance of antenna.
In the present embodiment, it is preferred that protective layer 122 can be the conductive silver slurry layer for being printed on surface A, i.e., by conductive silver paste
It is printed on formation protective layer 122 in surface A.It connects device 131 and can penetrate conductive silver slurry layer and contacted with conductive part 121, or
