Zusammenfassung:FIELD: antenna engineering; radio links primarily those operating in ultrashort-wave bands. SUBSTANCE: according to first version, antenna assembly has two antennas one of which is connected through phase shifter and other one, directly to first bridge one of whose outputs is connected through second phase shifter and other one directly to inputs of second bridge. One antenna is nondirectional and other one, directional. Five versions implementing antenna assembly circuit are described. EFFECT: provision for controlling directivity pattern shape (directional minimum of reception, positioning angle, two maximums, etc.); improved noise immunity. 10 cl, 15 dwg
