Abstract:
In the present invention, an antenna substrate comprises: an antenna; a ground member gapped from the antenna in the thickness direction; and a feeder layer positioned between the antenna and the ground member in the thickness direction. An intermediate ground member that is electrically connected to the ground member and a feeder line are disposed in the feeder layer. An excitation slit extending in the direction orthogonal to the thickness direction and a line slit extending in the direction orthogonal to both the direction in which the excitation slit extends and the thickness direction are formed in the intermediate ground member. The feeder line is positioned inside the line slit, and the excitation slit extends so as to intersect with the feeder line when viewed from the thickness direction.
