Applied Computational Electromagnetics Society Journal. ISSN: 1054-4887. Vol. 31, N.º 2 (2016), pp. 118-1251054-4887http://hdl.handle.net/10400.21/6647The knowledge of the dielectric properties of materials, for the design of several components and circuits at high frequencies, is mandatory. In this paper, we present a simple method for the estimation of the dissipation factor (loss tangent) of dielectric materials based on the reflection measurement of a single microstrip line, which is applied to some common known materials, such as FR-4 and Rogers RO3010 laminates. The obtained results match well with the data on the literature for the considered materials.engDielectric characterizationloss factor estimationmicrowavespermittivity estimationjournal article
