ULTRABROADBAND LOG-PERIODIC ANTENNA

摘要

FIELD: antenna equipment.;SUBSTANCE: invention refers to the antenna equipment, namely to the ultra-wideband antennas, which operate in the continuous range of ultrahigh (UHF), superhigh (SHF) and extremely high (EHF) frequencies and intended for use in the radio systems of various purposes. Antenna consists of two identical flat metallic log-periodic structures, which are mounted at the angle to each other, both log-periodic structures are designed in the form of the printed circuit board on one side of the flexible foil dielectric plate, which is bent to the desired angle at the gap between the crests of the structures.;EFFECT: technical result consists in extending the operating frequency range of the antenna to the high-frequency range.;1 cl, 2 dwg
