description The purpose of the present invention is to further reduce the size of a compact slot-type antenna in which a slot and a stripline are electromagnetically coupled. In a compact slot-type antenna 20, a stripline 40 is used rather than an electrical connection to perform electromagnetically coupled power feeding for feeding electric power by electromagnetic coupling. The stripline 40 is configured from a first line section 41 extending in the longitudinal direction of the slot 21, and a second line section 42 extending in an orthogonal direction, the second line section 42 being connected to the first line section 41, and the first line section 41 being arranged inside the projection region of the slot 21. One end side of the second line section 42 is connected to the first line section 41, and the other end side is connected to a high-frequency circuit. A compact slot-type antenna can be devised because the first line section 41, which is the tip portion of the stripline 40, is arranged inside the slot 21. Also, the antenna can be made even smaller at the same frequency on the basis of the new finding that forming a slit 22 that extends from the slot 21 to the side of a metal substrate 11 reduces the resonance frequency f.
