Selection of suitable material is a critical step in microstrip antenna design. Dielectric constant, thermal expansion coefficient, conductivity, mechanical properties and weight are the leading material properties in material selection. In addition to these factors, environmental impact, cost and size are among the most prominent design criteria. In this study a multi criteria decision making (MCDM) structure for material selection analysis in microstrip antenna production, is proposed. In this context, CRITIC-MAIRCA integration which is one of the MCDM approaches utilized to determine the best material for microstrip antenna. Dielectric constant, loss tangent and thermal expansion coefficient criteria are considered to select the best among eighteen different materials. The impact of each criterion on selection process is computed via CRITIC. To rank the alternatives taking into account criteria weights, MAIRCA was utilized. As a result, BaSrTi2O6 (bulk form) was found to be the best material for microstrip antenna manufacturing. This study provides an initial insight to practical material selection.
