Formulas available in the literature for the design of the physical properties of rectangular microstrip antenna elements are discussed, and their validity is assessed. Their variations have been experimentally examined by analyzing a set of newly designed antenna elements with substrates satisfying the criterion h ≤ 0.0815λ 0 for 2.22 ≤ ϵ r ≤ 10.2, where λ 0 is the free‐space wavelength, h is the thickness, and ϵ r is the relative permittivity of the dielectric substrate. New formulas that can determine the antenna physical properties and the effective dielectric constant are empirically determined. ©1996 John Wiley & Sons, Inc.
