FIELD: antenna engineering; ultrashort-wave transceiving antennas for relaying systems. SUBSTANCE: antenna has metal screen 1 mounting four dipoles of first channel 2 fed at progressive 90 deg phase shift, and second-channel radiator 4 in center of screen. Dipoles are, essentially, magnetic-type radiators. Opposing first-channel dipoles are installed in mirror-like position relative to each other. Relationship between different structural components and examples of implementing dipoles are given in description of invention. EFFECT: provision for simultaneous and independent operation of two channels at same frequency and polarization. 5 cl, 10 dwg
