PROBLEM TO BE SOLVED: To provide a reflector whose structure can be miniaturized or simplified, with handling of it being easy, and a broadcasting wave reception method using the reflector indoors.SOLUTION: A reflector 11 which reflects terrestrial digital broadcast wave is provided on a wall surface in a room, and indoor antennas are arranged with a predetermined interval on a front surface side thereof. The reception signal of the indoor antenna is inputted in a TV receiver. On the reflector 11, a plurality of resonators 22 (22a, 22b, ..., 22n) are disposed with a predetermined interval in lattice on a front surface of a printed board 21. The resonators 22 are provided with variable reactance circuits 26a, 26b, 28a, and 28b respectively at tip ends of half-wave dipole elements 24 and 25, and the capacitance of a variable reactance circuit is varied by a tuning voltage supplied from a tuning control part. A resonance frequency of each resonator 22 is tuned with a selected channel, and re-radiation is caused with the resonator 22 as a start point. Thus, a random characteristic in reflection caused at the time of wall surface reflection is reduced, for improved reception rate. |
