I need to place a trace from transceiver to SMA connector and need 50 Ohm impedance I have looked at several calculator and they all will reference to hte plane below - halfway there for what I need.  These traces will be surrounded by ground on the same layer also.  What I am looking for the formula that will specify clearance required for same layer at a specific frequency.  These are RF signals I am playing with any help is appreciated.
