Hi all,
I am trying to simulate a circular antenna with Momentum in ADS. It has 20 turns and the its a 2 layer PCB, where the top layer has the antenna.
I measured the antenna with the LCR Meter and Network analyzer and got the Resistance to be around 9.3 Ohms and impedance around 6.6 uH.
But, when simulating with ADS, i am not getting correct resistance value. I have used 1 oz copper
layer desc..
top - 1.37 mil thickness
prepreg - 59.05 mil thickness
bottom - 1.37 mil thickness
Also model: Sheet
material:conductivity (sigma): 5.7e7 siemens/m is given as input to ADS
Whereas the inductance value is accurate as measured in those meters.
Can someone please guide me why this mistake would have happened?
