Abstract

A radio device includes a rectangular substrate including first and second opposite sides and third and fourth opposite sides; a ground plane formed in the substrate, cut out along the third side from a corner at one end of the second side; a first monopole antenna extending away from the ground plane along the third side from a first feeding unit provided on the third side; a second monopole antenna extending away from the ground plane along the fourth side from a second feeding unit provided on the fourth side; and a ground element formed in the ground plane, extending toward the second side along the third side, from one end of the ground element connected to the ground plane. A length from the first feeding unit through the one end to another end of the ground element corresponds to one fourth of a wavelength of radio waves.
