PROBLEM TO BE SOLVED: To provide a wideband antenna which is reduced in size and weight in comparison with a conventional discone antenna while maintaining an input impedance. SOLUTION: The antenna is provided with a cone whose top is composed of a supply point, a radiating conductor composed of a structure which is formed by sequentially adhering and integrating m (m≥1) pieces of truncated cones and/or cylindrical objects to the bottom of the cone and a flat conductor including the supply point in the radiating conductor. Alternatively, the wideband antenna is provided with an n-angular pyramid (n≥3) whose top is composed of a supply point, a radiating conductor composed of a structure which is formed by sequentially adhering and integrating m (m≥1) pieces of frustums of n-angular pyramid and/or n-angular prisms to the bottom of the n-angular pyramid and a flat conductor including the supply point in the radiating conductor.
