Lossy capacitor replacement?

I'm using Murata GRM caps in an antenna matching circuit at 2.4 GHz,
and having some issues with the third harmonic being too high. Is
there a similar part in 0402 package that would be maybe slightly more
lossy at 2.4, and significantly more lossy at 7.5?

Thanks

Could be better at 7.2 GHz I remember the callsign, but where do
I know you from?

I'm a little fuzzy having been on this problem all night. It's hard
to google on "our caps are really bad at X ghz" Razz
