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.
- Last week
-
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)
-
Use THIS is more PRECISE (PS: also try rotating the tube gradually to get the POLARIZATION in the SWEET SPOT) Good work!

Dear Sir, After a long gap, I revisited this website and designed an dual band 2.4GHz and 5GHz omnidirectional antenna based on approximate online dimensions. I attempted to set up a wave port, but encountered meshing issues. I have attached the design file. Could you kindly help simulate the antenna? Thanks in advance. Omni_2.4GHz_5GHz.cst

These are what I've got as an improvement, You can see the speed was increasing a little bit. I've been expecting something better, however this is the best I can do and get so far!
-
Here is the built that I've just made. I attached the biquad into a PVC pipe, and I drew the coax from inside the pipe. The PVC pipe can slide inside the hole (see the 4th picture below). The last image showed the final work on its stand. I've got no measuring equipment or anything similar, but just relying on the windows stuffs. Tell me if there is something to adjust or to correct from my construction.
