Abstract
A biconical antenna according to the present invention includes a columnar dielectric member having frustum-shaped cavities extending respectively from an upper surface and a lower surface toward a center of the columnar dielectric member, wherein flat surfaces of apex portions of the frustum-shaped cavities are parallel and in opposition to one another; a frustum-shaped feeder portion made of a conductive film provided on an inner surface of the upper cavity; and a frustum-shaped ground portion made of a conductive film provided on an inner surface of the lower cavity. The present invention realizes a more compact biconical antenna by filling the dielectric member between the feeder portion and the ground portion of the biconical antenna.
