BICONICAL ANTENNA Russian patent published in 2013 - IPC H01Q11/10 

FIELD: radio engineering, communication.

SUBSTANCE: biconical dipole antenna has a pair of coaxial hollow cones facing each other with their vertices, and a feed line connected to the vertices of the cones. The cones are formed by 2N metal strips which are dipole arms and lie in pairs opposite each other on lateral conical surfaces which are bounded by the base in form of a circle; the inner volume of said cones is divided by circular metal plates which are parallel to the base of the cone into a row of cavities filled with a dielectric material with given relative permittivity ε_r, and which form a serial chain of semitransparent hollow resonators whose resonance frequencies form a log-periodic series or a series close to log-periodic. In such cases, a multi-resonant conical antenna, which is capable of operating in a wide frequency range without using loop lines, is used. In said antenna systems, antenna standing-wave ratio can be reduced (or reduction of the sufficient number of resonators).

EFFECT: wider operating frequency range.
