Abstract
A radio communication device of the present invention comprises a first antenna, a second antenna, a phase varying section which varies a phase of a first RF signal received by or transmitted from the first antenna, and a phase control means which causes the phase varying section to vary a phase amount which is a varied amount of the phase of the first RF signal received by or transmitted from the first antenna. Thus, it is possible to prevent that a size of a device configuration increases and avoid that a reception electric field level is lowered in a localized area.
Claims11
A radio communication device comprising:
- a first antenna;
- a second antenna;
- a phase varying means which varies a phase of a RF signal received by or transmitted from the first antenna;
- and
- a phase control means which causes the phase varying section to vary a phase amount which is a varied amount of the phase of the RF signal received by or transmitted from the first antenna,
- wherein the radio communication device is configured to receive packet data having the same content sequentially via the first antenna and the second antenna,
- wherein the phase control means causes the phase varying means to vary the phase amount repetitively in fixed cycles, and
- wherein when a cycle T1 in which the phase control means causes the phase varying means to vary the phase amount repetitively is T1 and a time length of data transmitted and received in a state in which the data is incorporated in the RF signal is T3, the phase control means causes the phase varying means to vary the phase amount such that a relationship of T1>T3 is satisfied.
