hi all. i want to simulate this paper in cst. i create the model in solid works and import it in cst,but i did not know any about appropriate boundaries for this structure,and also i want to know which setting i must use to get the H-plane sum pattern ans E-plane sum pattern? thank you all
I have measure electric field at a point in cst MWS software using TLM and transient solvers. 112005112006 I got ripple in the pattern rather than smooth pattern. But the pattern is correct atleast. Please help me to get smooth pattern. i have to change in the mesh settings or any thing else?
Hi to everyone I have a question that troubles me a lot and would be grateful if I could get a little help. I've designed a simple square patch antenna at 60GHz in cst (attached), frequency domain. The problem that I face is that I can't get the maximum gain at broadside. maximum is tilted by 30 degrees. I changed dimensions of the patch,

I am thinking of designing a Microstrip antenna. I am thinking of making a directive microstrip antenna. Obviously the work that I am thinking of doing should not be done by any one else. It should be unique at least at one area. But due to the lack of knowledge about how to start a project or approch for it I am unable to proceed. Some of the step
Dear all, I am designing a simple slot antenna (just a rectangular cut in the ground plane) at 75GHz on a thick Si substrate . The slot has a length of 740um and a width of 22um as shown in next figure 107466 for a small ground plane (1500 x 1500 um), the radiation pattern is perfect. It resembles that of a dipole but

Earlier i was using Transient Solver to simulate the body and the results were okish (Combined Gain = 7 dB). A friend of mine told me that for better results I shoul
how i can plot e plane and h plane patterns such az attached picture in cst?
I think, in cst, and similar in HFSS, you get to see the radiation patterns using a field monitor. You can select the types of field you want to monitor You can then make the resulting plot options display it as Cartesian or Polar instead of 3D
