I have decided to use M20057-1 as an active GPS antenna. I am using Quectel L96 GNSS module. There is an internal chip antenna on L96 module and I have tried the performance of L96 without M20057-1 before. I have achieved to get location data while the device at outdoor but I couldn't get the location data at indoor. That's why I have decided to use an active antenna to improve performance. I have just received the PCB with M20057 and I am not able to get the location data for both indoor and outdoor with M20057-1. So It is obvious that there is a problem with the design of the printed circuit board. But I don't know that the problem is matching circuit(does it affect the performance that much), layout or schematic. So Could you please review my schematic and layout to check is there any problem? I know that it quite hard to detect the problem in this way but even your approaches might be pretty useful. I am going to share screenshots of schematics and layout. Waiting for your responses. Best Regards.
