- Biconical antenna
A biconical antenna consists of an arrangement of two conical conductors, which is driven by
potential , charge, or an alternatingmagnetic 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).
