Transmission device and antenna

Abstract

A transmission device including: a transmission substrate for transmitting a signal, the transmission substrate including a feeding line and a capacitive coupling conductor that are provided on one side of a plate-shaped dielectric substrate and a ground conductor that is provided on other side of the dielectric substrate; and a connector for inputting and outputting a signal, the connector including an inner conductor and an outer conductor that is provided outside of the inner conductor, wherein the connector is provided on the one side of the dielectric substrate on which the feeding line and the capacitive coupling conductor of the transmission substrate are provided, and the inner conductor of the connector is connected to the feeding line, the outer conductor is connected to the capacitive coupling conductor, and the ground conductor of the transmission substrate is not connected to the outer conductor of the connector.
