Hi guys, could anyone share your experience on how to draw/simulate Radial stub in hfss. Because my design is a 3-D stucture (CPW-TO-Microstrip), and i know the RS could be easy simulate just by drag the icon in ADS. But in hfss, I'm newbie. Many thanks.:D:D

I am trying to emulate the single stub matching network example given in Pozar's Microwave Engineering using a microstrip realization on a 14mil FR4 (dielectric constant = 4.4) board. The 50ohm thickness works out to be 0.675mm for this board. However I am not getting anywhere close to 50 ohms at the port in my hfss design. I have att

Please help me in drawing radial stub using hfss. I have tried arc, polyline etc. But I want to have a radial stub with a thickness, which means it is 3D and not 2D.
I need to know how to draw a 3D radial sub in hfss. Radial stub is like a slice of pizza.
Please help!! It is urgent!!!

hffs is a field solver. a double stub tuner is a circuit element. You are using the wrong program to simulate the double stub tuner. Start off on a linear simulator that uses S parameters and treats transmission lines as black boxes with a length, impedance, and deielectric constant.
you are tying to use a pneumatic Jackhammer to drive a tiny t

1. The most important excitations are the waveport and the lumped port, and in my experience the second is even more important - but the solutions are/can be slightly less accurate. The waveport is actually a 2D eigenmode solver itself, so it finds (or tries to find) the correct excitation modes to apply. It can be used only on (perfect) conducting

The probe length is generally chosen to be less than the height of the DRA, to avoid probe radiation. YOu might consider a stub on the other side for tuning the antenna. (Added) other side of DRA on same surface.

The models are implemented in practically every simulation software.
I usually proceed the following way. For example a radial stub to substitute a open stub in the bias network of an amplifier. I design the square stub and then it its a starting point for optimization.
