TIGHTLY-COUPLED PCB GNSS CIRCUIT AND MANUFACTURING METHOD

摘要

A tightly-coupled printed circuit board (PCB) circuit includes components mounted on a PCB enabling smaller integrations using decoupled lines extending between reference layers, such as ground planes, which lines form isolation islands on the PCB. The decouplers are capacitors, inductors and/or resistors in tandem with ground layers of the PCB. The isolated components can comprise high-frequency RF antennas and receivers, for example in a GNSS antenna-receiver circuit. Multiple antennas can be connected to one or more receivers with multiple, independent RF front end components by RF traces, which are either embedded within the PCB.
