Specific embodiments
Embodiment below in conjunction with accompanying drawing describes the present invention in detail.In order to describe the present invention more intuitively, 2, accompanying drawing
It is the part intercepting accompanying drawing 1, it is accordingly required in particular to it is noted that the radio-frequency (RF) switch in the accompanying drawing of all antennas is all with an electricity
Sense carrys out symbolistic instead of.
As an embodiment, described PCB top and low side have clearance zone, putting for antenna module
Put, wherein the left side of 2 main antenna placement PCB, for placement symmetrical above and below；2 high frequencies are placed on the back of the body of PCB
Right side of face, is placement symmetrical above and below equally.
As an embodiment, described becket has 6 gaps, wherein in the middle of top and middle each one of low side, the right side
Side becket and each 2 gaps of left side becket, these gaps are all that symmetry is cracked and size is identical, and the size in gap is permissible
The most effectively adjust.It is same because becket is divided into 6 parts, described becket by these 6 gaps
