My rule of thumb is 2 to 3 linewidths, or 2 to 3 substrate thicknesses, whichever is smaller. Beyond 3, it is very hard to predict coupling in microstrip. ...

I'm sure others will answer, but that 2 MHz bandwidth will act to move the microstrip resonators pretty far apart. You would be better off using a coupling...
