ABSTRACT:
To realize a receiving system that can excellently receive radio signals before and after a body insertable device, which is a radio signal source, is inserted into a subject, the receiving system has a first receiving antenna (1), a second receiving antenna (2), and a receiving apparatus (3). The first receiving antenna (1) is used when the body insertable device is outside the subject. The second receiving antenna (2) is used when the body insertable device is inserted into the subject. The receiving apparatus (3) performs a receiving processing on radio signals received through the first receiving antenna (1) or the second receiving antenna (2). In the receiving system, a receiving antenna connected to an antenna connector (13) provided in the receiving apparatus (3) is switched between the first receiving antenna (1) and the second receiving antenna (2) corresponding to a difference in propagation states of radio signals transmitted from the body insertable device before and after the body insertable device is inserted into the subject. Consequently, the receiving system that can excellently receive the radio signals before and after the body insertable device is inserted into the subject is realized.
