LOG-PERIODIC RESONANT ANTENNA Russian patent published in 1997 - IPC

FIELD: radio engineering. SUBSTANCE: antenna has linear grip of slot radiators 1 cut in walls of resonators 2. Every resonator is made as truncated cone with sector recess at angle α. Edges of recess are coupled to flat metal surfaces 4. Truncated cones are made of full cone 3 the axis of which coincides with common edge of surfaces 4. Resonators are excited by supply line 9 to which exciters 15 are connected via tubular conductors 14. Relations of dimensions of construction members are given at which maximum gain factor and antenna efficiency are obtained. EFFECT: more efficient construction. 3 cl, 5 dwg
