Single Port Coplanar Waveguide Resonator for measuring reflection

Hi all,
I am trying to simulate a coplanar waveguide resonator and obtain the resonant frequency and Q-factor using RF module in COMSOL. I used the lumped port boundary condition and with two ports (with wave excitation ON for one of them), I get resonance at around 90 GHz. However, I want to simulate a CPW resonator with a single port, as experimentally I will be measuring the reflection (with resonance corresponding to a dip in 
).
When I remove the second port, I see no sign of resonance despite sweeping frequency from 2 to 250 GHz. is always > 
dB.
It would be great if someone could give some pointers about anything that I may be missing here!
Tl;dr: I want a CPW resonator with a single port to show a dip in indicating resonance.
Thanks!
