Biconical antenna
Biconical antenna
A biconical antenna consists of an arrangement of two conical conductors, which is driven by potential, charge, or a 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 transceiving signals from 30 MHz to 300 MHz.
If one of the cone's angle at the vertex is 180 degrees (or if one of the cones is reduced to a plane), it is called a discone.
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 of a biconical antenna (commonly used for UHF transception).
