PROBLEM TO BE SOLVED: To obtain a laminated aperture surface antenna which can suppress a mode, wherein an electromagnetic wave is propagated in a dielectric layer when the dielectric layer for matching is mounted on a slot and change the direction of the main bean of a radiated electromagnetic wave. SOLUTION: A spatial resonator is surrounded with an antenna conductor wall, composed of an upper main conductor layer 2 having a rectangular aperture part 5 on the top surface of a dielectric substrate 1, a lower than conductor layer 3, multiple through-conductors 6 which electrically connects the upper and lower main conductor layers 2 and 3 at the periphery of the aperture part 5, and a subordinate conductor layer 7 which electrically connects the through- conductors 6 and a slot 4 for power feeding to the lower main conductor layer 3 is formed in parallel to two opposite sides of the aperture part 5. Here, the thickness of the spatial resonator isλ0/8 toλ0/2, and the width between the two opposite sides of the aperture part 5 isλ0/4 to 2λ0, whereλ0 is the signal wavelength of a high-frequency signal in the laminated aperture surface antenna.
