AppCAD_setup.exe ,,,for wave port,on YouTube,search "waveguide port creation tutorial in CST"
-
Sir, may I use the formula provided in CST to determine the size of the wave port in HFSS? Also, could you please advise on the appropriate height of the radiation box?
-
Sir, could you kindly direct me to the website?
-
Another option...
-
I followed this forum and tried to do a simulation for this frequency (L-band 1500-1700 MHz)....for last mystery of maritime communication-satellite Inmarsat!!! https://www.radioscanner.ru/forum/topic50990-11.html

Understood, Sir. Thank you for the clarification.
-
You use WHAT WORKS (that'll be DISCRETE PORT 1st and WAVE Port at the end) Same for Solver mesh settings
-
Besides frequency, is there any other reason you choose a discrete port over a lumped port sir?
-
Actually, my friend worked on this design in HFSS and shared the dimensions with me. He mentioned that some of the values were taken from online sources, while the rest were based on approximations.
-
,,,,where did you get this project from...???
-
Many thanks for pointing out the need to add ground to the coaxial cable. Your advice is truly valuable sir.
-
355.....594 mm
-
,,,must add ground to coaxial cable...!!!!
-
Thank you so much for the clarification and guidance sir. Your explanation really helped me understand the correct way to assign the wave port. I truly appreciate your support and time.
-
I'm glad to have found this website and your support. While I can handle complex designs, I struggle with port assignment and impedance. I look forward to learning from experienced people like you. I’m truly grateful to you sir thank you.
-
Face select inner+pet+shield+outer edge , then assign wave port (ALL of them should be leveled) puting a PORT on the END of an ANTENNA is a NO-NO
-
Still workin on it (good antennas BAD FEED NETWORKS !) I'll upload it if it works give me time After the simulation is OK on Port impedance Z (should be 50 ohms ) Electronics = Cables= Antennas (50Ohms=50Ohms=50ohms)
-
Thank you so much sir, could you please send this corrected design file. And where i can see the OHM stuff in CST.
-
I noticed the simulation includes a connector. Is it necessary to simulate with one? Also, if the antenna ends with a copper rod, I have assigned the wave port by selecting the rod’s end face. Similarly, for a copper tube, I selected the tube’s face and assigned the wave port. Kindly confirm if this method is correct.
-
Those TWO collineal NEED an adapter to SHOW 100 Ohms in the middle (50ohms on coax) Two identical antennas of 50ohms would give 25ohms in the middle not right I ran one alone and is promising...
-
Those TWO collineal (2,4ghz) NEED an adapter to SHOW 100 Ohms in the middle (50ohms on coax) Two identical antennas of 50ohms would give 25ohms in the middle not right
-
Can you tell me the max and the min depth of this 355?
-
First of ALL BOTH Your Coax cable HAVE NO SHIELD... Adding a SHIELD present a NEW problem (they would be DANGLING in the AIR -No Connected to ANYTHING)
