Vivaldi antenna in cst
I am trying to model a vivaldi antenna in cst and am having a lot of trouble getting the geometry to work. Does anyone have a model file i can look at or any advice for creating my model?
reference impedance
In CST i created a model using a waveguide port and when i look at the smith chart the reference impedance is listed as varying. How do i define the reference impedance for this model?
Parametric sweep in FEKO
How do i perform a parametric sweep in feko? i want to plot the impedance vs. distance between two antennas.
advice??

Is no one smart enough to answer this question?
Antenna Feeding
When using software such as cst or feko is it necessary to simulate how the antenna is "excited". For example if i know i will be using a balun to connect a dipole antenna to a coax line do i need to simulate the balun with the coax or can i just use a port to excite the...
I am fairly new to CST and I am trying to determine if it is possible to plot specific frequency values for the smith chart and S-parameter polar plot. Currently the results provide a trace over the range of all frequencies, but I would like to be able to set specific frequencies for which to...
How do i create a polar plot of an antennas farfield as a function of spherical angle phi? I can only generate a 3D plot and I'm basically trying to get a cutplane of this result.
graphing input impedance
How would I create multiple curves on one frequency graph with each curve representing a different diameter for the antenna. I would like to have a plot of impedance vs. frequency with several curves representing various antenna diameters.
