MODULE OF SIGNALS RECEIVER IN SATELLITE RADIO NAVIGATION SYSTEMS Russian patent published in 2010 - IPC H05K1/14 H05K1/18 

FIELD: radio engineering.

SUBSTANCE: module comprises multi-layer printed circuit board with conducting and insulating layers and metallised holes, which are used to provide interlayer electric connections, and board carriers printed conductors and electric radio elements of electric circuit intended for reception and processing of signals in satellite radio navigation systems (SRNS). Printed conductors and electric radio elements related to units of analog signal processing are grouped in zone of analog signal processing. Printed conductors and electric radio elements related to units of digital signal processing are grouped in zone of digital signal processing. Intermediate zone with screening ground planes is arranged between zones of analog and digital signal processing. Multi-layer printed circuit board consists of three joined multi-layer fragments - upper, medium and lower ones, interacting with each other by adjacent contact sites arranged at edges of according conducting layers in neighboring fragments. At the same time upper fragment includes group of those related to zone of analog signal processing, lower fragment - group of those related to zone of digital signal processing, and medium fragment - group of those related to intermediate zone. Medium fragment has H-shaped profile of cross section, which forms inner cavities of multi-layer printed circuit board, where inner electric radio elements of analog and digital signal processing zones are arranged. At the same time in lower external conducting layer of digital signal processing zone there are external electric radio elements of this zone and contact sites arranged along edges and serving for external connections, and in upper external conducting layer of analog signal processing zone there is a ground plane connected to underlying surface of receiving antenna separated by dielectric from resonating element connected by vertical pin-probe to input strip line of analog signal processing zone. Specified strip line is made in the form of printed conductor surrounded at sides in its conducting layer, and also on top and bottom in neighbouring conducting layers of analog signal processing zone by screening printed elements.

EFFECT: development of compact module with inbuilt receiving antenna, which requires less area for its location.
