i found a calculator for split rings and one with a outer diameter of 66cm and a trace width of 60mm would resonate at 27MHz and needs about 14pF of capacitance on the split of the gap

but what if you put another split ring inside it, it'll be different

i could be wrong but i think the calculator already includes the inner ring https://srrcalculator.blogspot.com/p/calculator.html
