ANTENNA ASSEMBLY Russian patent published in 2005 - IPC

FIELD: antenna engineering; television and corporative, departmental, and public radiophone communications.

SUBSTANCE: novelty is that separating screen is newly inserted in antennaassemly metal reflector in the form of cylindrical surface with part of (O.6 - 1.4)λ width cut along generating line, where λ is wavelength; this screen is disposed in symmetry axis within reflector to create two in-phase excited apertures and functions to narrow directivity pattern in H-plane. In this way proposed antenna incorporates provision for two-fold narrowing of directivity pattern in H-plane (to 30 - 60 deg.) while maintaining narrow (about 20 deg.) directivity pattern in E-plane.

EFFECT: enlarged functional capabilities of antenna assembly.
