Department of Radiation 19 flows to the earth point 3 of the second Department of Radiation 14.To sum up, in the present embodiment mode on metal shell 1
Form three kinds of antennas.
May be appreciated, it is also possible to by antenna body direct-coupling on metal shell 1.
It should be understood that the feeding classification of the antenna form on metal shell 1 can be directly feedback or coupling
Feedback.
Antenna assembly 100,200,300 in this utility model embodiment is micro-by the first gap 11 and first
Seamed belt 12 forms the first insulating segment and metal shell 1 is separated into the first Department of Radiation 13 and the second Department of Radiation 14,
And the first distributing point 2 is electrically connected to the first Department of Radiation 13 by the first match circuit 4 to carry out feed and makes the
One Department of Radiation 13 becomes the radiation arm of antenna assembly 100, the first Department of Radiation 13 to be electrically connected to earth point 3 to make
Second Department of Radiation 14 forms radiation ground, thus metal shell 1 is formed antenna assembly 100, this antenna assembly
100 by utilizing the structure of mobile terminal metal shell 1, and swept area is big, and need not additional designs sky again
Beta radiation body, not only increases the radiation efficiency of antenna assembly 100, and makes mobile terminal overall structure
Simplify, advantageously reduce the cost of mobile terminal.
Being described in detail this utility model embodiment above, specific case used herein is to this reality
Being set forth by novel principle and embodiment, the explanation of above example is only intended to help to understand this
The method of utility model and core concept thereof；Simultaneously for one of ordinary skill in the art, according to this reality
By novel thought, the most all will change, to sum up, this explanation
Book content should not be construed as restriction of the present utility model.
