Hi,
i have simulated a 15dB cavity coupler using HFSS.
simulated S-paraameters are not mathcing to measured results......
S(1,1)- Measured S11 is around -20dB, but simulated model is giving around -15dB
S(1,3)- Measured S13 is around -13dB±0.5dB, but simulted model is making around -11.9dB±0.5dB over the frequency band 650-3900MHz. Solution frequency is 2.275GHz.
Is the size of the lumped port only making this or any other problem?
i can send the simulated model.
thanking you in advance
