okay i see now

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

this is just small-ish magloop

i’ve seen some people make magloops out of bike rims, it’s similar sized. the smaller it is the lower radiation resistance, higher currents and voltage on capacitor, narrower bandwidth, and lower efficiency. i don’t remember how it scales but efficiency goes up fast with size, 1m dia magloop is already better. downside is that tuning becomes impossible on higher bands (capacitance required for this is below minimum capacitance of capacitor that you have)

will it antenna? i think it will

split ring resonator has already two different lengths of paths so - even without accounting on how these two interact - you could expect two different frequencies where it’s resonant, with peaks perhaps overlapping to a useful degree making a decently wide band possible. it looks a bit like halo antenna with parasitic, downside being that it’s probably a bit hard to feed it, circumference has to be halfwave on lowest frequency and if made for HF it’d be gigantic

i think it’s more useful to think of magloop as extremely shortened, low impedance, low bandwith halo antenna

I hear that this happens sometimes, but nowhere near normal times, more like during evacuations from warzone and so on
