In step 304, judge whether the rotational angle of the bottom of projection with respect to the horizontal plane is more than 0；If more than 0,
Into step 305；If no more than 0, (bottom projected overlaps with horizontal plane, that is to say, that the bottom of terminal is relative to level
Face does not rotate), then into step 306, and within step 306, keeping the antenna of present terminal, constant (i.e. terminal ought
Preceding reception antenna continues as reception antenna).
In step 305, judge whether the bottom of projection with respect to the horizontal plane rotates clockwise；If so, then enter step
307；If it is not, then enter step 308.

Antenna performance is identical, the antenna optimal to obtain current receiving efficiency, it is only necessary to judge the bottom of terminal with respect to the horizontal plane
(such as step 304), if do not rotated, constant (such as step of antenna of present terminal is maintained for either with or without rotating
306)；In the event of rotation, it is only necessary to which the direction for judging to rotate (such as step 305), if rotating clockwise, just can will
The antenna of present terminal top left side (when the screen of terminal is towards people) is as reception antenna, otherwise just by present terminal top
The antenna of (when the screen of terminal is towards people) is as reception antenna on the right side of portion, that is to say, that two days at the top of terminal are linear
