Abstract
An antenna device includes a ground plate, a patch section parallel to, and spaced apart from, the ground plate, a first short circuit section having a plurality of first conductive elements that electrically connect the patch section and the ground plate, and a second short circuit section having a plurality of second conductive elements electrically connected at one end to the ground plate. The plurality of first conductive elements are arranged in a circle with a first radius from a patch center point and provide a preset inductance. The plurality of second conductive elements are arranged in a circle with a second radius from the patch center point and provide a preset inductance.
