I am currently working on a project that involves creating a custom PCB. The board has a UBLOX MAX-M8 GPS Module, as well as a Rainsun GPS1003 SMD GPS Antenna.
I’ve created versions of this PCB in the past with the antenna right next to the GPS module as shown in the old_pcb photo below. This system would get GPS time after a few minutes, but never was able to get a position fix. I had to solder a LED leg to the pad and antenna to separate it from the PCB to get it to work.
I noticed on other boards that use this GPS and similar antennas that the antenna is separated from the main PCB on a section that usually sticks out and is separated from other components. In my new PCB, I did something similar (as you can see in the new_pcb photo), but I wanted to see if anyone had any insight on this.
