Document Type and Number:
WIPO Patent Application WO/2015/105066
Kind Code:
A1
Abstract:
[Problem] To control application of a bias voltage appropriately in accordance with characteristics of a variable capacitance element. [Solution] A control device according to the present invention is provided with (A) a variable capacitance device including a variable capacitance element, and (B) a control unit configured to apply a control voltage having a first polarity to the variable capacitance device during a third time period including a first time period to perform communication using the variable capacitance device and a second time period not to perform communication before the first time period, and configured to apply a control voltage having a second polarity opposite to the first polarity to the variable capacitance device during a sixth time period including a fourth period to perform communication and a fifth period not to perform communication before the fourth period.
