Abstract
An array antenna apparatus includes a first antenna element resonating at a first frequency and a second antenna element resonating at the first frequency, and includes a first connecting line that connects the first connection point located in the first antenna element with a third connection point located in the second antenna element, and a second connecting line that connects the second connection point located in the first antenna element with a fourth connection point located in the second antenna element. Electrical lengths of the first and second antenna elements and those of the first and second connecting lines are set so that a phase difference, between first and second high-frequency signals respectively propagating through first and second signal paths, becomes substantially 180 degrees at the first feeding point, and then, the array antenna apparatus resonances at the first frequency and the second frequency.
