Biconical antenna

Small biconical microwave antennas (up: 1–18 GHz, down: 0.5–3 GHz)

DIY DVB-T butterfly antenna, applicable in the so-called core area

In radio systems, a biconical antenna is a broad-bandwidth antenna made of two roughly conical conductive objects, nearly touching at their points. Biconical antennas are broadband dipole antennas, typically exhibiting a bandwidth of three octaves or more. A common subtype is the bowtie antenna, essentially a two-dimensional version of the biconial design which is often used for short-range UHF television reception. These are also sometimes referred to as butterfly antennas.
