[ W = \fracc2f \sqrt\frac\varepsilon_r + 12 ] where (c) = speed of light ((3\times10^8) m/s)

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
