For example, some 0.5mm ceramic piece can give nice signal improvement if glued above DC decoupling gaps. I have doubts about how it works. Because sometimes covering part of gap gives better result, so maybe it alters impedancea a bit and works as matching? For example, if we currently somewhere on a Smith chart, where small changes in line lengths gives big impedance change. Or dielectric plate reflects radiated signal back to microstrips and nothing to do with impedance matching?
