1. A radio frequency IC device comprising:

  • a radio frequency IC element including an input/output electrode;

    a first base including an intermediate electrode; and

    a second base including a radiation electrode;

    whereinthe intermediate electrode is capacitively coupled to the input/output electrode via a first capacitance having a capacitance value C1;

    the radiation electrode is capacitively coupled to the intermediate electrode via a second capacitance having a capacitance value C2;

    the first capacitance and the second capacitance are connected in series with one another between the radio frequency IC element and the radiation electrode; and

    the capacitance value C2 is greater than the capacitance value C1.
