An antenna device includes: an antenna panel; one input terminal through which a high-frequency signal is input; and a feeding circuit which distributes the high-frequency signal input to the input terminal to a plurality of antenna elements provided on the antenna panel. The feeding circuit includes: at least one first-stage branch circuit which includes one input and two outputs; at least two second-stage branch circuits which receive outputs of the first-stage branch circuit and include one input and two outputs; and a combining circuit which includes two inputs and one output and receives two outputs selected from the outputs of the first-stage branch circuit and outputs of the second-stage branch circuit.
