Abstract
To obtain a more favorable radiation pattern even in a case of arraying a plurality of antenna elements. An antenna device includes a dielectric substrate, a plurality of antenna elements that disposed along a first direction and respectively transmits or receives a first wireless signal and a second wireless signal having different polarization directions from one another, and a ground plate provided with a long slot to extend in a second direction in a region corresponding to a region between first and second antenna elements next to each other, and a length L in the second direction of the slop satisfies a conditional expression below where a wavelength of the wireless signal is λ, a relative dielectric constant of the dielectric substrate is ε, and a relative dielectric constant of a dielectric located on an opposite side of the dielectric substrate with respect to the ground plate is ε.
