For my dipole antenna, i used one EDGE PORT with AWR AXIEM simulator, which is while its simulating shows "port 1 de-embedded" (Great, it worked)..
I have the output simulations with S11, VSWR .. i read my graphs and found that S-Parameters is within the range of 875.13 - 887.16 MHz. And the VSWR, is within the range of 875.1 - 887 MHz. But at the side of each graph, there is some points which i don't understand for S11 (0.9961104 for 875.13 and 0.9961208 for 887.13MHz) & VSWR (54.186 for 875.1 & 54.224 for 887MHz). My question is,
- what are these points? is it input return loss or for something else?
- I read that i can get the radiation patterns graphs from E-field visualization (add annotation, to view the structure mesh and current) by:
+ add new graph > add measurements > Data > (Con_etheta, PPC_ephi and PPC_etheta) to show the output radiation patterns, but when i try that, it shows some errors and ask to disable advanced freq. sweep AFS, or put ports at the sidewalls of the antenna but it slow down my simulation and i can't get any results?
- Is there any mistake i might have done through my simulation or setting options? how by adding annotation could help me with the simulation?
- it shows an error if i used the simulator for the AWR EM & CST MWS- EMSocket co-simulation interface (5:24:19 PM An unexpected error occured in the remote em simulator ( CST MICROWAVE STUDIO ) Error Text = Internal Error : Attempt to access the DC surface resistance of a real conductor)
-I tried to import it to CST Microwave office and i had first to connect the port and define the brick for the substrate but i don't understand two things:
1) Boundaries and (open , electric or magnetic - for yin, zin) what is the suitable option for me?
2) It shows at the message window while its simulating by (transient solver) that (the simulation whould take long time: check the mesh to avoid the mesh small steps) which i don't understand too.?
-besides till now its simulating (Processing excitation, count down: 6325) anyway i will post the results later.
Thank you a lot Mr. Manju for your big help and sharing your knowledge.
Note: I can attach my output graphs or design if that would help.
