Title:
HIGH-FREQUENCY ANTENNA MODULE AND ARRAY ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/073644
Kind Code:
A1
Abstract:
A high-frequency antenna module is provided with: a substrate (1); an input port (6) to which an RF signal is inputted; a distribution circuit (8) which distributes the RF signal inputted to the input port (6); a plurality of amplification units (3) which each comprise a plurality of amplifiers (11, 12, 13) that are cascade-connected and each amplify the RF signal distributed by the distribution circuit (8), and which are disposed to be rotationally symmetric around the distribution circuit (8) on the same side as the distribution circuit (8) of the substrate (1); a plurality of antennas (2) which are provided on the opposite side to the side on which the amplification units are provided of the substrate (1), and each radiate the RF signal amplified by the amplification unit (3) corresponding thereto to space; and a plurality of RF signal supply parts (15) which each supply the RF signal amplified by the amplification unit (3) to the antenna (2) corresponding thereto.
