Abstract
A receiving circuit includes: a mixing section configured to mix a local oscillation signal with a positioning signal that is received by an antenna within a constant receiving frequency band that includes a resonance frequency of the antenna, and output a mixed signal of the local oscillation signal and the positioning signal; and a control section configured to sequentially select any of a plurality of carrier frequency bands used in the positioning signal, and configured to switch the resonance frequency of the antenna to a specific frequency within the selected carrier frequency band, and switch a frequency of the local oscillation signal, based on the specific frequency and a frequency of the mixed signal.
