I would like to assign wavegiude port in CST for '' bent antenna design'' but it does not work and this message below appear when I run simulation (Waveguide ports must be aligned with cartesian coordinate planes for the transient solver.) does anyone know how I can deal with that problem and what's the solution for? Thanks in advance.
u have two ways
Discrete ports (for feeding coaxial connector probes)
Waveguide port but in that way you try to make bending where one end connected to horn while the second open should its aperture be in XZ or YZ or YX planes
It is better to use discrete port. You can trust on it. I have tested CST discrete port to feed a bend design and compared the results with same design in HFSS. Both works almost the same.
thanx for all. I need waveguide port coz it give me good matching S11 compare to discrete port thats why I'm interested in wavegude one
look,it simple. try to make same open as your horn waveguide in xz or yz or xy,ok
then try to loft two surfaces from extension option, but be care two surfaces should be solid. you can make large scaling for that new bending part and subtract the former one from it u will get your hollow bend.
Add a bending to you antenna feeding in order to make it fall into one of the 3 planes.
I am facing the same problem while trying to embed my patch antenna inside 2 material cad design which is imported earlier. Any solution?
I'm also facing this problem..any one plz give a proper way to fix it..
actully i want to connect a waveguide port in the bend antenna..but it didn't work...
when I run simulation (Waveguide ports must be aligned with cartesian coordinate planes for the transient solver.) shows
only solution i came up, not changing the cartesian coordinate planes. instead change the bend structure to fit in.
I didn't get it, why you were changing the cartesian coordinates? I have the same error but my structure is pentagonal shape with multi ports.
i am not sure about your case. but for me, i had to embed antenna in an imported cad model. so, if i move patch antenna to fit in the cad design, waveport doesnt work. Please check if you have overlaps of any surface with assigned waveport.
In case of bent antenna you must be facing this problem. While assigning port in local WCS (u, v, w) you should see that the port should lies in any of plane of the global co-ordinates (X, Y, Z). Its better to bend the other model like voxel model (head, hand..) rather then bending the antenna to avoid this problem.
Problem will be solved if mesh is altered according to feeding. Alignment is important for simulation.
Rotate the port in the way that it is aligned with cartesian coordinate planes.
Maria Paszkiewicz can you little bit explain about this? Basem Aqlan have you get the answer? I ma facing the same error in CST. Can you explain little bit about this error. Thanks
Muhammad Abdul actually I tried this and I don't remember if it helped at the end. What helps for sure is changing the solver to frequency domain.
Basem Aqlan , you can use coaxial SMA port instead of normal waveguide port. You can import SMA port from antenna magus
