发明名称 Helical antenna with adjoining insulator units
摘要 A helical antenna permitting a diminution in dielectric loss includes an antenna section divided into short insulator units with a molded body over which antenna elements are helically would, and the insulator units are connected in tandem. The relationship among the insulator units is so configured that, when they are fitted into one another for connection, the end faces of element units constituting the antenna elements are brought into electric face contact with each other.
