[ L = \fracc2f\sqrt\varepsilon_reff - 2\Delta L ]

A microstrip patch antenna consists of a flat rectangular (or circular) conductive patch on a dielectric substrate (circuit board material), with a ground plane on the opposite side. patch antenna calculator

[ \frac\Delta Lh = 0.412 \frac(\varepsilon_reff + 0.3)(W/h + 0.264)(\varepsilon_reff - 0.258)(W/h + 0.8) ] [ L = \fracc2f\sqrt\varepsilon_reff - 2\Delta L ]
