Abstract
An antenna substrate includes an antenna, a ground member arranged at an interval from the antenna in a thickness direction, and a feed line layer located between the antenna and the ground member in the thickness direction. An intermediate ground member electrically connected to the ground member and a feed line are arranged on the feed line layer. An excitation slit extending in a direction orthogonal to the thickness direction and a line slit extending in a direction orthogonal to both the direction in which the excitation slit extends and the thickness direction are formed in the intermediate ground member. The feed line is located inside of the line slit. The excitation slit extends to intersect the feed line as seen in the thickness direction.
