Patent ID: 8369814

Claim:
A mobile communication device, comprising: a first signal processing means for performing predetermined signal processing on a transmission signal transmitted via a first antenna or a reception signal received via the first antenna; a second signal processing means for performing predetermined signal processing on a transmission signal transmitted via a second antenna or a reception signal received via the second antenna; a reception suppressing means for suppressing the transmission signal transmitted via the second antenna or the reception signal received via the second antenna from being received via the first antenna, while at least one of the predetermined signal processing by the first signal processing means and the predetermined signal processing by the second signal processing means is being performed; wherein, while at least one of the predetermined signal processing by the first signal processing means and the predetermined signal processing by the second signal processing means is being performed, the reception suppressing means performs adjustment such that a resonance frequency of the first antenna is shifted away from a frequency of the transmission signal transmitted via the second antenna or a frequency of the reception signal received via the second antenna, thereby suppressing the transmission signal transmitted via the second antenna or the reception signal received via the second antenna from being received via the first antenna; and wherein, in a case in which a frequency of the transmission signal transmitted via the first antenna or a frequency of the reception signal received via the first antenna is a frequency that is closer to a frequency of the transmission signal transmitted via the second antenna or a frequency of the reception signal received via the second antenna as compared to a predetermined frequency defined in advance, the reception suppressing means performs adjustment such that the resonance frequency of the first antenna is shifted away from the frequency of the transmission signal transmitted via the second antenna or the frequency of the reception signal received via the second antenna, thereby suppressing the transmission signal transmitted via the second antenna or the reception signal received via the second antenna from being received via the first antenna.
