Dear all:
I encounted some problems when simulate a simple antenna structure; the model, zoomed port&lumped element and the s11 resultsas, are all shown in the attached file. The simulation conditions are:
1. discrete port, Gaussian excitation
2. one lumped element, serial RLC ( R = 2.4, L = 2.4e-8, C = 0)
3. frequency range: 0.5~3.5GHz
4. mesh properties:
line per wavelength = 30, lower mesh limit = 30, smallest mesh step = 0.1
5. open boundary, add space = wavelength / 8
6. background matrial: normal
7. simulation accuracy = -50dB, PML = 5 layer
seems everything is ok, but the s11 result is quite strange. I tried a few times, still cannot get some reasonable results.
So, anybody, with experiences of CST MWS simulation, please take a look of my model and s11; kindly give me some suggestion or hint. thanks a lot in advance.
regards,
tenderne
