Abstract

PURPOSE:To minimize an antenna space and to prevent the layout of a small receiver from being influenced by the impedance of an antenna by forming the inductance between two facing conductors by a plate conductor. CONSTITUTION:A spacer (d) is equipped between an antenna element (a) and a bottom board 2, and a plate transmission line with a constant interval is formed. Between two conductors to which the element (a) and the bottom board (b) face, a flexible printing substrate (c) is provided, and by the waving line on a substrate (c), an inductance is formed. Respectively both edges (l) and (m) or the waving line are connected through the element (a) and the base board to a small receiver circuit, an intermediate point (n) is connected to a feeding edge, the substrate (c) executes the same function as the transformer and an antenna space is smaller. By the waving pitch change, the position of the intermediate point (n) is not changed, and the impedance matching of the antenna and the small receiver and a circuit is executed without being influenced by the impedance of the antenna.
