Abstract
An antenna device according to an aspect of the present disclosure includes a zeroth-order resonant antenna and a first-order resonant antenna. The zeroth-order resonant antenna includes a base plate, a platy radiation element, and a connection conductor connecting the base plate and the platy radiation element. The zeroth-order resonant antenna is configured to transmit and/or receive a first linearly polarized radio wave in all directions perpendicular to the first linearly polarized radio wave by zeroth order resonance. The first-order resonant antenna includes the base plate shared with the zeroth-order resonant antenna, and a first radiation element located on the same plane as the base plate. The first-order resonant antenna is configured to transmit and/or receive a second linearly polarized radio wave perpendicular to the first linearly polarized radio wave by first order resonance.
