ABSTRACT:
A smart antenna device includes: first and second weighting units provided to correspond to two antennas disposed apart from each other so as to weight received signals inputted from the antennas, respectively; an operating unit that obtains a ratio of a weight of the second weighting unit to a weight of the first weighting unit; an adding unit that adds a signal outputted from the first weighting unit and a signal outputted from the second weighting unit to each other; and a phase shifting unit that makes phases of the two signals equal to each other.
