PROBLEM TO BE SOLVED: To provide an aperture antenna having high radiation efficiency in which variation in radiation characteristics is suppressed. SOLUTION: The aperture antenna comprises a dielectric layer 2, a high frequency line 1 comprising a line conductor 3 and a first ground conductor layer 4, a slot 5 formed to intersect the line conductor 3, a second ground conductor layer 8 having an aperture opposing the slot 5, and a shield conductor 6. Connection region of the shield conductor 6 in the second ground conductor layer 8 is projecting into the aperture of the second ground conductor layer 8. COPYRIGHT: (C)2008,JPO&INPIT
