MULTIBAND ZIGZAG-SHAPED LOOP ANTENNA Russian patent published in 2001 - IPC

FIELD: broad- band ultrahigh- and very-high-frequency antennas. SUBSTANCE: antenna using loop and, in particular, zigzag radiators in its operation and designed for operating in television transmission and communication systems, as well as in other fields of application and other wavelengths where capability of operation in broad band and small transversal dimensions (planar design in direction of radiation) are essential has at least one more or several geometrically smaller zigzag-shaped loop radiators for shorter-wave high-frequency bands; radiators are electrically interconnected in series through communication link and phasing lines or in parallel through frequency-selecting filters, or in parallel and in series and supplied with power from feeder; planes of zigzag-shaped loop radiators operating in some wavelength bands are spaced through 0.1- 0.15 of maximal wavelength of respective band from reflector surface. EFFECT: reduced space requirement, facilitated manufacture. 3 dwg
