Abstract

PLANAR SLOT ANTENNA GRID ABSTRACT A planar slot antenna grid containing a number of waveguide-slot radiators (1) having wide reverse side and wide outer side faces (3a, 5a) in which there are obtained, respectively, exciting slots (9) of coupling and radiating slots (8), the said faces lying correspondingly in two parallel planes, and a waveguide-feeder network (10) formed by waveguide distributors (14) of power and feeding wave- guides (13), channels (12a) of which are communicating with the exciting slots of coupling. The waveguide-slot radiators (1) represent strip-line waveguides (1a) comprising a common dielectric substrate (2),the reverse side of which is covered by metallized coating (3) serving as a common wide reverse side face (3a) of the waveguide-slot radiators (1), each wide outer side face (5a) of which represents a strip-line (5) made of alternating narrow and wide segments (6, 7) formed on outer side face (4) of the dielectric substrate (2).
