ABSTRACT:
An antenna device of the invention comprises divider/combiner means12that divides or combines a received signal into signals having a first phase distribution represented by an odd function, phase adding/removing means14-1that adds phases having a second phase distribution represented by an even function to the signals, or removes the phases from the signals, and a plurality of antenna elements20arranged in an array configuration, that transmits or receives the signals to which the phases have been added.
