Hi researchers, I am searching for some accurate way to do the circuit modeling of planar CPW-fed monopole antennas. I have gone through the literature where mostly circuit modeling is done using Foster canonical forms. If so then ;
1. How can I calculate the inductance and capacitance values apart from the resistance which I have found directly from real impedance in CST? It is mentioned to use ADS software for calculation. I couldn't understand how to get the input impedance plot.
2. I have somehow understood how to model the antenna alone but if the antenna is backed by AMC surface then how it could be realized?
Looking for the best possible answer to my above questions. Thank you so much.
