Antenna device

Abstract

An antenna device includes a first conductive plate in a board shape, a second conductive plate in a board shape, a short-circuiting section, and a connecting section. The second conductive plate is disposed to face the first conductive plate with a space therebetween. The short-circuiting section is disposed between the first conductive plate and the second conductive plate, has a housing space housing an electronic component, and is connected to both the first conductive plate and the second conductive plate. The connecting section extends from the electronic component disposed inside the short-circuiting section toward the outside of the short-circuiting section without being electrically connected to the short-circuiting section and the first conductive plate, and extends between the first conductive plate and the second conductive plate from the outside of the short-circuiting section without being electrically connected to the first conductive plate, to be electrically connected to the second conductive plate.
