Abstract
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.

An array antenna device comprising:
- a substrate;
- a linear 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,
- wherein 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,
- wherein a first portion of each of the loop elements which is closest to the linear strip conductor is spaced from the linear strip conductor by a prescribed distance with an air gap, and
- wherein a cut part of each of the loop elements is arranged at a position other than both of the first portion of each of the loop elements and a second portion of each of the loop elements which is opposite to the first portion.
