Communication device

A communication device comprising:

• a communication unit that has adjustable communication characteristics, said communication unit having (i) a communication antenna for transmitting and receiving a carrier wave and (ii) an adjustment unit to adjust one or more of the adjustable communication characteristics;
• a setting unit that sets adjustment values used in adjustment of the communication characteristics of the communication unit on the basis of parameters corresponding to one or more target applications each of which is an application which is a process target among parameters of the adjustable communication characteristics set for applications relating to communication;
• and
• an adjustment control unit that controls the communication unit to adjust the communication characteristics on the basis of the adjustment values,
• in which one of the adjustable communication characteristics is a Q value of the communication antenna, and
• in which the adjustment unit includes a circuit to adjust the Q value of the communication antenna,
• in which when a plurality of target applications are present, the setting unit (i) determines parameters of adjustable communication characteristics including the Q value for all of the target applications which overlap each other and which enable communication to be performed for all of the target applications, and (ii) upon determining presence of overlapping parameters, sets adjustment values corresponding to the parameters of the overlapped communication characteristics including the Q value such that adjustment values corresponding to parameters of non-overlapping communication characteristics are not set and utilized.
