Biconical antenna

A biconical antenna consists of an arrangement of two conical conductors, which is driven by potential, charge, or an alternating magnetic field (and the associated alternating electric current) at the vertex. The conductors have a common axis and vertex. The two cones face in opposite directions. Biconical antennas are broadband dipole antennas, typically exhibiting a bandwidth of 3 octaves or more.

A common variant is the Discone antenna, where one of the cones has a vertex angle of 180 degrees (or is reduced to a plane).

A simple "conical monopole" antenna is a wire approximation of the solid biconical antenna and has increased bandwidth (over a simple monopole). A "bowtie antenna" is simple broadband wire approximation in two dimensions of a biconical antenna (commonly used for UHF transception).
