description A high-frequency antenna module includes: a substrate; an input port to which an RF signal is inputted; a distribution circuit configured to distribute the RF signal inputted to the input port; a plurality of amplification units which each have a plurality of cascade-connected amplifiers configured to amplify the RF signal distributed by the distribution circuit, and which are arranged on a side of the substrate provided with the distribution circuit to be rotationally symmetric about the distribution circuit; a plurality of antennas provided on a side of the substrate opposite to the side provided with the amplification units, and each configured to emit the RF signal amplified by the amplification unit corresponding thereto to a space; and a plurality of RF signal supplying portions each configured to supply the RF signal amplified by the amplification unit to the antenna corresponding thereto.
