Abstract
A planar array antenna using a multi-layer substrate having an intermediate layer conductor in a laminated face comprises: four pieces of planar antenna elements disposed at each of geometrically square shaped apexes; first and second slot lines formed in the intermediate layer conductor, and intersecting each other; first to fourth microstrip lines formed along each side of geometrical squares so as to be coupled to each antenna element, and at the same time, electromagnetically coupled to first and second slot lines at both ends of these slot lines; and fifth and sixth microstrip lines, the top end sides thereof traversing the first and second slot lines, respectively, so as to be electromagnetically coupled to the first and second slot lines.
