ABSTRACT:
An antenna device forms a discone antenna and comprises a pole-shaped base member10acomposed of dielectric material. The pole-shaped base member10ahas a cone-shaped inner space formed therein. In an inside surface of the pole-shaped base member10a, a first antenna element11is formed by patterning a metal conductor layer. Further, on a plain surface facing the outside of the pole-shaped base member10a, a second antenna element12is formed also by circularly patterning a metal conductor layer at the side of a top of the first antenna element11with a predetermined space being kept between the top of the first antenna element11and the second antenna element12. The first antenna element11and the second antenna element12are located with respective rotation central axes thereof being corresponding with each other.
