TOUCH PAD WITH ANTENNA
First Claim
1. A touch pad with an antenna, comprising:
- an electrode;
a control unit configured to detect proximity of an object to the electrode and a position of the object based on a change in capacitance which is associated with the proximity of the object to the electrode;
an antenna; and
an antenna driving unit configured to supply power to the antenna,wherein the control unit is further configured to control the antenna driving unit to;
drive the antenna at a first power level such that the antenna has a normal output when the proximity of the object is not detected; and
drive the antenna at a second power level lower than the first power level such that the antenna has to an attenuated output or zero output when the proximity of the object is detected.

Abstract
A touch pad with an antenna includes an electrode, control means for detecting proximity and a proximate position of an object on the basis of a change in capacitance which is associated with the proximity of the object to the electrode, an antenna, and antenna driving means for supplying power to the antenna. When the proximity of the object is not detected, the control means controls driving of the antenna driving means to set an output of the antenna to an output during ordinary driving. When the proximity of the object is detected, the control means controls driving of the antenna driving means to attenuate the output of the antenna with respect to the output during ordinary driving or to set the output of the antenna to zero.
