How to improve fabrication tolerance of a circularly polarized microstrip antenna?
Hello everyone. I’m working on a circularly polarized truncated patch antenna, but the design is hyper-sensitive to dimensions. A ±0.1 mm deviation completely collapses the axial ratio, making it impractical for standard fabrication. How can I solve this problem?
Edit: Even if I just increase the meshes without changing anything in the design, the axial ratio collapses.
