I was designing a microstrip patch array antenna with inset feed on a bent structure, But I am facing issues while assigning port. I have already designed a unit patch on the bent structure, so plz help me with the array.
Thanks in advance.
Nonplanar lumped or wave ports seem not feasible. The voltage and current line sources could work, but they offer little port information. The recommended way is by including the actual feeding structure in the model, such as a short piece of coaxial line, or simply an SMA.
If not, for CST, a discrete port assigned based on two points could work. In HFSS, regarding microstrip line-type feed on a curved surface, it is possible to draw an auxiliary feedline (a non-model sheet) on the ground and define a planar inset lumped port cut through the two feedlines. The aligning line of this port is defined by the midpoints of the intersecting line of the two feedlines and the port surface.
Boyuan Ma Sir, please provide me with the steps as I am not getting the terms like how to draw auxiliary feed, as I am a beginner. I f you have any video kindly give me the link
Thank you so much for helping every1
Boyuan Ma Thank you so much, sir for this much help. I ran the program but it's showing some error and I am not getting that. I am trying to work on it.
Habeeba Khan I created a simplified model since yours is too large for my PC. I have run the simulation. It worked.
By saying "auxiliary", I meant assigning non-model parts in HFSS to facilitate modeling.
My HFSS version is 2019, yours is 2020 R2. I am not sure about the compatibility.
Besides, for curved objects, the "Assign mesh operation -> surface approximation // Apply curvilinear meshing" function is recommended to ensure accuracy.
Boyuan Ma sir it's working, thank you so much sir for helping in such a hard time.
Habeeba Khan Select the post and define the line of the port. Hope this will help.
