    Abstract: A coaxial line includes a central conductor long in one direction, an outer peripheral conductor, and a dielectric located therebetween and having a first end face facing a transmission line. A wall body includes an opening leading to the first end face and including an annular space contacting the first end face. An outer diameter of the annular space is larger than that of a space opposite the first end face in the opening. The central conductor includes a first section having a first thickness and at least partially projecting from the first end face and a second section having a second thickness smaller than the first thickness and located within the dielectric; an end of the first section on an anti-projection side is located between the first end face and a specific position within the dielectric in a longitudinal direction of the central conductor. The specific position is a position separated from the first end face toward the inside of the dielectric by 1/8 of an effective wavelength of a transmission signal.

    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.
