in a 50 ohm system maximum radiation efficiency occurs when antenna (load) radiation resistance = 50 ohms and total loss resistance in the load = 0 ohms.

antenna radiation efficiency % = radiation resistance divided by radiation resistance + total loss resistance.

in a 50 ohm system resonance occurs when there is no inductive or capacitive reactance present at the antenna (load) feedpoint @ a given frequency

for frequency @ resonance, (X) reactance = 0..
