Split Ring Resonator (at 20 GHz) loaded with CPW (Coplanar Waveguide) [G-S-G] with pitch size (of GSG probe) 0.15 mm!
50 Ohm impedance of CPW was matched, but after loading SRR no resonance occurred. S11 and S21 curves are appearing totally flat. I loaded CSRR also, and changed different parameters but it seems coupling is not occurring (one possibility why resonance is not there). Could any one suggest me? I am intending to resonate SRR/CSRR at 20 GHz. I checked S11,S21, and Impedance (real, Imaginary) graphs till 80 GHz, but no resonance !

re(Z11) =750 Ohms thus if loaded with 50 Ohms, Q<<1
Should I increase the impedance of signal line?
I could not understand.
