Hello
I am designing an antenna on Si substrate (resistivity = 300 ohm -cm) at 24
Ghz.I want to calculate the loss tangent for this substrate .I calculate it as
follows
conductivity = 1/ resistivity
Tan d = conductivity /( epsilon * 2* pi* f)
I get a value of 0.25 .My question is that if this calculation is right then
why loss tangent decreases with the increase in frequency and if this
calculation is not right then whats the right way to calculate the loss tangent
from resistivity alone.
Thanks
Atif
