摘要： An array antenna device includes a substrate, a strip conductor formed on one surface of the substrate, plural loop elements formed on the one surface of the substrate, and a conductor plate formed on the other surface of the substrate. Each of the loop elements has a circumferential length that is approximately equal to one wavelength of a radiated radio wave, and is disposed at such a position as to be coupled with the strip conductor electromagnetically, and the loop elements are arranged alongside the strip conductor at distances that are equal to the one wavelength.
