Hi what are the design equations for elliptical shaped antenna for uwb (3.1-10.6)GHz with partial ground and truncated feedline?

20 July 2025 0 2K Report

i want to know the design equations for ellipse radius (major axis and minor axis) also truncated feedline widths upper and lower and substrates dimensios (i am using polyimide with 0.1mm thickness and epsilon of 3.5).
