Hello!
I would like to ask you about this error:Mesh is empty using CST. Any suggestions about which could cause such error ?!
Note: I am simulating a structure which has mm as a unit and GHz FOR THE FREQUENCY unit.
Thank you !!
Greeting!
I want to know how to distinguish between the cases when there is an electrical coupling an those we have a magnetic coupling.
an example is shown in the picture attached where both occur but I couldn't say/explain where or why the couplings occur.
Hope I made myself clear...
thank you very much!
I feel like confused about the figures of volker they don't tell much to me :-(
Ps: could you please specify the planes by xy and yz the terms horizontal and vertical depends on the structure positioning.
thx!
Hallo,
I have a loop monopole antenna while visualizing the E and H patterns I get them swaped (E must be H and
vice versa). Any ideas about what could cause such thing!
Note: I took E plane (phi=0º) and H plane (phi=90º)
Regards!
Thank you, very much for the open sources, I appreciate it!
could you give any arguments for your choice or references , I will be grateful!
because I have been looking into the literature for a quite long period and I can't decide maybe because I am new to this field !
regards!
I didn't build an antenna yet but it will be a slotted one (simple and not stratified).
Now, I am confused about the adequate method that could be applied to get the characteristics (phase constant, attenuation,..etc), as going through the literature most used ones are MoM and Mode Matching...
dear all,
I want to know which method is more adequate to analyse the characteristics of a SIW antenna and what are its advantages compared with the rest of the methods?
many thanks!
Hello!!
Yes, I am using a vector network analyzer (VNA). supposing I will use the cable that comes with the VNA, it will not be useful for any other kind of measurements due to the coaxial-Stripline transition that I have to consider in one end of it.
but I have a doubt a bout the ground plane...
