RADIO-ELECTRONIC BLOCK WITH IN-BOARD SCREENING Russian patent published in 2005 - IPC

FIELD: radio communications.

SUBSTANCE: device has multi-layer electronic board with outer and inner conductive layers, carrying conductors and electric radio-elements, grouped in screened functional zones using barrier and plane screens. Each screened functional zone has own barrier screen, positioned along its perimeter, and own ground plane, serving as its plane screen, while ground planes and barrier screens are constructively not interconnected, and ground links, connecting ground planes of screened functional zones together and to shown point of Earth potential input, pass through appropriate gaps in screening conductors of barrier screens, while barrier screens are connected to same point of Earth potential input by own ground conductors.

EFFECT: higher efficiency.
