hfss rlc boundary

hiall,
how to simulation with RLC boundary condition in HFSS?.. For eg. if i have a CPW with RLC termination how to define it?.Just define a sheet and proceed like defining a port? theres nothing abt this in teh manual
kindly clarify
thanks in advance
 

yes, just like defining lumped port. Do keep its dimension as smaller as it could be.

Regards,
 

thanx.
can this RLC be inside the box(for radiation boundary condtion). i.e. i'll have a box then inside it i'll have cPW or mustrip. one end of the tr.line will have one port(touching the box) other end will be terminated with RLC(wont touch the box)
i'll simulate and see
thanx

sorry one more doubts...

in microstrip the RLC must the defined between strip and ground. no problem

BUT in CPW do we need to define it between signal line and one ground or BOTH ground....do we need to connect Z/2 to both gnds or just Z to one gnd?
 

yes, you can put it inside the computational domain (air box), I didnt see any problem.

for CPW RLC termination, I suggest this structure:

thankyou very much. i'll simulate and discuss with u
 

why "Do keep its dimension as smaller as it could be." Will you please ellaborate more on this point? such as how small should it be? How will it affect the result? any general rule? Many thank!
