Abstract

An antenna module () includes a dielectric substrate (), antenna groups (A,B) including a plurality of antenna elements (), RFICs (A,B) configured to supply radio-frequency power to the antenna groups (A,B), a divider () configured to divide a radio-frequency signal between the RFICs (A,B), and a ground electrode (GND). The RFICs (A,B) are mounted at a mounting surface () of the dielectric substrate (). The divider () is provided closer to the mounting surface () than to the layer in which the antenna groups (A,B) are provided. The divider () includes a first path having lower impedance and a second path having higher impedance. When viewed in plan view in a normal-line direction with respect to the mounting surface (), a cavity () is formed at a portion of the ground electrode (GND), the portion facing the second path.
