摘要：To form a signal processing circuit and an antenna apparatus that do not need acircuit for adjusting the resonant frequency of a resonant circuit or resonant-frequencyadjustment work and that are downsized. An antenna coil (AL) and a capacitor (CO) forman antenna resonant circuit (AR). An impedance matching circuit composed of capacitors(C1, C2, C3), a first coil (L1), and a second coil (L2) is provided between the antennaresonant circuit (AR) and a wireless IC (11). The first coil (L1) and the second coil (L2) aremagnetically coupled.
