Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the following problem: when an array antenna is to be constructed by arranging a plurality of elements of microstrip antennas on a flat surface, a parallel flat plate mode occurs between first and second ground conductors and coupling between the elements occurs in the parallel flat plate mode and hence a gain of the array antenna lowers and side lobe rises.SOLUTION: Mutual coupling between elements in a parallel flat plate mode is suppressed by arranging connection conductors at sufficiently shorter intervals than a resonance wavelength of a radiation conductor plate between a first ground conductor plate and a second ground plate around a microstrip antenna.
