Biconical antenna are dipole antenna composed of two roughly conical conductive components which nearly touch at their points. The appearance of the cones gives it the nicknames of bowtie antennas and butterfly antennas. Biconical antenna achieve a broadband frequency bandwidth through their double-cone structure, their signals amplified by the cones' enhanced conductivity. An omnidirectional radiation pattern is generated in the H-plane by the structure and a coaxial feed is connected to the antenna’s center. Biconical antennas are used for electromagnetic compatibility applications including emission testing, immunity testing, measuring the efficiency of RF shielding and more. Biconical antenna simplify bipolar conductive emission testing compared to previous iterations like half-wave dipoles, which do not allow for continuous sweeps like biconical antenna do.
