# Step 5: Edge resistance approximation (cavity model) Rin0 = 90 * (er**2 / (er - 1)) * (L / W)

Choose your material (e.g., FR-4 or Rogers) and note the height ( ) and dielectric constant ( ϵrepsilon sub r patch antenna inset feed calculator

The impedance varies sinusoidally along the length of the patch. The standard equation governing the input impedance $R_in(y_0)$ at a distance $y_0$ from the edge is derived from the transmission line model: # Step 5: Edge resistance approximation (cavity model)

A high-quality is not magic; it is deterministic. To get correct results, you must provide accurate inputs. Here is what the calculator requires: patch antenna inset feed calculator

): The distance the feed line must penetrate the patch to reach the 50 Ωcap omega point is often approximated by:
