ADS-B in (receive only) antenna does not require a ground plane of any size. A simple TED stick/ball transponder antenna on a bracket will do nicely. Just mount it low in the fuselage with the best possible downward conical exposure (not blocked by metal objects) for the best results.
For ADS-B out (transmit & receive), you will need a ground plane and the appropriate size antenna for the system (1090ES or UAT) you are using. A UAT system would use a slightly longer antenna and larger ground plane than the traditional 1090ES transponder type due to its slightly lower 978 frequency.
120mm square ground plane for transponders (1090ES)
130mm square ground plane for UAT systems and appropriate antenna
Put the antenna in the center, .020 aluminum is fine for this use, radius the corners ¼” or so
I’ve installed several…all work very well.
