In embodiments of the present invention, what described FPC plate adopted is the FPC plate of on & off switch. The FPC plate of prior art breaker in middle key comprises three shown in Fig. 2 pad, and wherein the pad of Far Left (from the orientation shown in Fig. 2) is reserved pad, and its top is originally with Pu Tongqu and is connected. The top of reserved pad and paving copper are separated and leave by the present invention, and using the input terminus of reserved pad as antenna modulation signal, i.e. sky heat input feedback point; The main body of the antenna feedback of sky heat input point PAD1, ground pad PAD3 and Pu Tongqu being joined together to form again, is equivalent to become the FPC plate of original on & off switch antenna; Meanwhile, on & off switch energy feedback point PAD2 and on & off switch shell fragment 201 are electrically connected, then this FPC plate 20 also retains the function of original on & off switch, material is thus formed the FPC plate 20 that is integrated with antenna and on & off switch. The FPC plate of embodiment of the present invention system selector switch key, as the main body of antenna, is make it be subject to ectocine less because the control mode circuit simple, peripheral of on & off switch is less, makes that performance after antenna is relatively stable, better effects if. If selecting other buttons, such as sound size key or digital keys, its operation is comparatively frequent, and circuit placement-and-routing and control mode more complicated, it is easy to affect the work of antenna.
Should be understood that, in prior art, FPC plate has multiple layer, the Pu Tongqu of the FPC plate 20 of the antenna integrated and on & off switch of the present invention, sky heat input present some PAD1, on & off switch energy feedback point PAD2, ground pad PAD3 and on & off switch shell fragment 201 is all arranged on same layer, and sky heat input feedback PAD1, ground pad PAD3 and Pu Tong district are linked together by conductor (copper) in this layer.And on & off switch energy feedback point PAD2 and on & off switch shell fragment 201 are that the line of walking by another layer links together, it is electric connection.
Wherein, described sky heat input feedback point PAD1, the feedback of on & off switch energy point PAD2, ground pad PAD3 are disposed adjacent successively.
