摘要： The object of the invention is to provide a small-sized noncontact IC card reader/writer that can enhance the efficiency of an amplifier at a low cost. To achieve the object, in the invention, a loop antenna that supplies electric power and a send signal to a noncontact IC card by electromagnetic induction and acquires a receive signal from the noncontact IC card by load fluctuation, a first resonance circuit for resonating the loop antenna with a desired first frequency, a radio transmitter that supplies electric power and send data to the loop antenna via the first resonance circuit and further, a radio receiver that acquires the receive signal from the loop antenna via a second resonance circuit connected to the loop antenna via a coupling capacitor and resonated with a desired second frequency are provided, the radio transmitter and the radio receiver are respectively connected to CPU, and a low-pass filter for removing a high frequency, a class E amplifier and a modulator are connected to the radio transmitter in series.

摘要： An antenna device includes: a radiator having a meander portion; and a conductor shorter than the radiator which is disposed opposite to the radiator. A coaxial cable is connected to the radiator and conductor. Respective line lengths of the radiator and conductor satisfy a predetermined relation with respect to a wavelength of a signal to be transmitted and received. The antenna device achieves at least one of improved antenna characteristics, downsizing, and improved mechanical strength.
