Abstract
An antenna device includes an electronic substrate having a surface on which an electronic circuit is formed, a plate member having a linear expansion coefficient different from that of the electronic substrate, a fixture that fixes the electronic substrate and the plate member, a feed antenna element provided on the electronic substrate, a parasitic antenna element provided on the plate member at a position facing the feed antenna element, and an inter-element distance adjustment mechanism that adjusts a distance between the feed antenna element and the parasitic antenna element.
