): Before calculating the inset, the calculator determines the impedance at the very edge of the patch, which is significantly higher than 50 Ωcap omega Inset Depth ( patch antenna inset feed calculator
It allows the feed line and patch to be on the same layer, simplifying fabrication. ): Dictates the resonance frequency (roughly half a
This is the relative permittivity of your PCB material (e.g., FR4 is approx. 4.4, Rogers RO4350B is 3.48). Higher constants reduce the size of the antenna but decrease bandwidth and efficiency. FR4 is approx. 4.4
Let’s run a high-frequency example.
