That is unfortunate. I am an RF engineer though. So, I can't help but focus on the single element as well.
I have been reading about feeding techniques. Seems like you can do a lot of improvement on side lobe levels by just scaling the excitation amplitude to be lower for extreme elements. The...
Thanks a lot for the explanation. I have a question though, why do you say that array designers do not spend time on optimizing a single antenna? In the end, the array performance is going to depend on the single element as well.
I am designing an antenna array for base stations. I want to read more about the feeding techniques that are used in arrays. I read somewhere about chebyshev and dolph-chebyshev feeds to reduce the side lobe levels. How to decide which feeding technique is best?
Yeah I thought that I would need to change the type. Will definitely try that. Have you done co-simulation to tune filters? If yes, what do you use to model the coupling between cavities? Shorted transmission lines or series capacitance? What should be the length of the transmission line in that...
I have started co-simulation. But the solution is not optimizing to the goal values. I am using the ratio S11/jS21 as the optimization function. I am not sure what the issue here is. Is it the range of values of capacitances in the co-simulation? Can anyone share some references that guide on...
Thank you for the reply! I have been using driven modal setup since I am exciting a coax cavity using an SMA connector. Do you think I can use driven terminal setup here? I am trying to follow the procedure explained in this paper - https://ieeexplore.ieee.org/document/967097.

Hi, I am trying to setup cosimulation in HFSS to tune cavity filters. What should be the port impedance of the lumped ports assigned between resonator and the ground? Using impdance like 50 or 100ohms will detune the filter. Will this have any effect on the tuning when running circuit simulation?
