We have designed a board with a Beltii antenna and a UBLOX Zoe receiver. We have foreseen a Pi-Network on the board. Using a simple solder bridge, the board received sats and can fix positions; not great reception, but it works. The board and the ground plane is very small e.g. 18x18mm.
However, after soldering the recommended match inductance and capacitance (from the measurement with the network analyzer) we don't see any sat's anymore. Can the layout of the PI network prevent the function? Is it possible to provide the layout to Antenova for review as we are planning a new revision of the board?
