Abstract
In an antenna element, a planar ground conductor layer on an insulation substrate is connected to ground. A radiation conductor layer radiates and/or receives high-frequency signals. The radiation conductor layer is in or on the insulation substrate and above the planar ground conductor layer. A lower principal surface of the radiation conductor layer overlaps an upper principal surface of the planar ground conductor layer as viewed in an up-down direction. The ground conductor is in the insulation substrate and connected to the ground potential. An upper end of the ground conductor is above the radiation conductor layer. The ground conductor layer is spaced away from the radiation conductor layer as viewed in the up-down direction. Only a conductor through which the high-frequency signals are transmitted and a conductor connected to the ground potential are between the ground conductor and the radiation conductor layer.
