摘要： A radio terminal device has an antenna element, a coil, a switch, an RF circuit section and a conductive substrate. The switch is used to switch between a case where current distribution exists only in the antenna element and its vicinities and a case where the current distribution exists not only in the antenna element and its vicinities but also in other places. Additionally, the switch is switched in accordance with the usage pattern in which the user uses the radio terminal device (e.g., telephone call and data communication). This allows the transmission/reception to be performed with the antenna polarization and directivity suitable for the usage pattern. Thus, there can be provided a radio terminal device that exhibits a reception characteristic suitable for a respective situation.

摘要： Antenna elements are provided along a linear line at regular intervals to be parallel to each other. The antenna elements receive signals transmitted from a communicating partner and output the signals to a receiving beam former. In the receiving beam former, phase shifters phase-shift the received signals input from the antenna elements of an even element number by π. A combiner adds the received signals that are phase-shifted by π in phase shifters and the signals input from the antenna elements of an odd number to form a received beam. With this configuration, it is possible to realize an array antenna apparatus of a small and simple configuration that reduces the radiation of radio waves to the human body and to other equipment and that is influenced little by the human body and by other equipment.

摘要： A phase shift section phase-shifts the second band-restricted signal to a first phase-shifted signal and a second phase-shifted signal having a phase that is different from the phase of the first phase-shifted signal by 90 degrees. A first signal mixing section mixes the first band-restricted signal and the first phase-shifted signal. A second signal mixing section mixes the second band-restricted signal and the second phase-shifted signal. A phase difference calculation section calculates the phase difference value from the first mixed signal and the second mixed signal stripped of frequencies other than a desired baseband frequency. A polarization calculation section calculates reception polarization from the first reception field intensity value, second reception field intensity value and phase difference value.
