ABSTRACT:
The antenna circuit and wrist radio instrument of the present invention compensates for slippage in the resonance frequency of antenna circuits caused by such as the wrist thickness of the person wearing them, and by being worn on the wrist and then not worn, and can always tune to a set frequency. Accordingly, the present invention is one that can automatically receive a set frequency signal stably and with a set sensitivity, with no need for special adjustments.
