    Fixing an monopole simulation in CST

    sorry for the latest reply, i've doing a lot of simulation here. And i haven't open the edaboard until these weeks It means: 1. lines per length --> make it higher 2. Click the mesh properties. and chose the specials, and find the "refine at PEC/lossy metal" to make it higher than 5. I am...

    how to reduce sidelobe of Antenna waveguide using CST?

    thank you for your reply. What do you mean a corrugations? actually i am using Artificial Magnetic Conductor. It's related with the EBG. but, anyway, i couldn't find the sidelobe reduce significantly. Do you know why? thank you very much...

    Reducing side lobes of antenna over EBG ground plane

    Hi everyone,sorry for asking this. I really need to talk about this topic because it was related. i would like to ask about the sidelobe suppression. I'm using CST and also an antenna waveguide 8 s a lot. Anyway, i have found the frequency of my Antenna around 9.4 GHz. But, the sidelobe really...

    Fixing an monopole simulation in CST

    you could check on the mesh definition view. Maybe you could adjust the lines per wavelength to the high. and the equil~ ratio to the high. i forgot the name. sorry. I think, if you get the mesh high than 1 million, it would be more accurate. And also, if you use the transient solver, you...

    How to reduce the first sidelobe level of microstrip antenna array

    you could use the Electronic Band GAp structures, that's for the sidelobe suppression and also the backlobe reducing.

    how to reduce sidelobe of Antenna waveguide using CST?

    Hi everyone, i would like to ask about the sidelobe suppression. I'm using CST and also an antenna waveguide 8 s a lot. Anyway, i have found the frequency of my Antenna around 9.4 GHz. But, the sidelobe really spread off. Im using EBG to reduce it, with Taconic TLY epsilon 3.2, and also with...
