PHASED-OUT ANTENNA ARRAY Russian patent published in 2001 - IPC

FIELD: microwave engineering; miscellaneous radar stations including on-board mounted ones. SUBSTANCE: antenna array has microwave signal distribution system and set of radiators with ferrite phase shifters in-between each incorporating waveguide that accommodates microwave ferrite insert; it also has external magnetic core, coils connected to inputs of control device, and magnetically permeable plates installed between magnetic cores and waveguide walls of phase shifters. Mentioned plates may be made, for example, of permalloy, electric steel, or ferrite. EFFECT: reduced level of side lobes, enhanced gain and facilitated manufacture of antenna array. 1 dwg
