but try to introduce as many voids as possible
ok, so the next version gona have a air gap then
tapering end of side plates into a triangle shape
great idea, gona add that to the next version too
tapering end of side plates into a triangle shape
thought about that too, the capacitor kinda has long leads on it, they could act as circumference extensions for the loop, i tryed shortening the loop a bit and it improved the SWR a bit, i now managed to get it down to 1.46 at 27mhz (before loop shortening it was 2.6). sadly that seams to be the limit of what shortening can do. Now got a SWR of 1.05 at 31,58Mhz…hope the next iteration of the capacitor moves that down to 27Mhz

i was thinking more like, thin external plastic shell and empty cells inside, perhaps with another thin plastic shell on inside, and internal metal shell (on plastic support?) fitting in snugly, for mechanical stability, idk 3dprinting
keeping leads short and nonmagnetic (dramatic reduction in skin layer depth) would be a good thing because of losses, but the longest object in capacitor would be just capacitor plates, and either way in wavelength terms it’s rather small. more precisely you can model it as open transmission line stub with some weird and low impedance, but it’s so small that you don’t have to
