Abstract: An antenna module includes a multilayer board, a phased array antenna that includes antenna elements arranged on an outer face of a second conductor layer included in the multilayer board and adjusts one or more beam directions of the antenna elements, a radio frequency (RF) chip that is arranged on an outer face of first conductor layers included in the multilayer board and outputs the radio frequency signal, a matching circuit that is arranged on the outer face of the first conductor layers and adjusts matching between impedance of the antenna elements and impedance of the RF chip, a through hole that couples the first conductor layers and the second conductor layer, and one or more vias that are on an outer side in a diameter direction of the through hole and couples the first conductor layers.
