Here this is done by increasing the loss tangent of the dielectric, \(\tan\delta\), to \(0.1\). This is much higher than that of any useful substrate. The reflection coefficient of the high loss line is shown in Figure \(\PageIndex{4}\).
WebiMAPS New England Chapter WebOct 28, 2024 · In this study, software named CST Microwave Studio was used for microstrip patch antenna design. Polylactic Acid from Esun (Esun PLA+) with a relative dielectric constant of 2.54 and a loss tangent of 0.015 was chosen as the suitable substrate material for the designed antenna.
WebFeb 19, 2005 · Yes it's correct that tan δ = σ/ωε. Loss tangent is the ration b/w the imaginary and real parts of the complex permittivity. where the complex permittivity can be defined as εc = ε-j (σ/ω) The valie of the loss tangent describes how lossy a material is, if σ » ω ε, it represents a very lossy material or a very good conductor. WebJan 28, 2024 · Prominent materials considered for substrate parts are: Denim fabrics with the relative permittivity $\unicode{x20AC}\mathrm{r}=1.67$, and the loss tangent tan $\delta=0.085$ and FR4 (lossy) with the dielectric constant $\unicode{x20AC}\mathrm{r}=4.3$, and loss tangenttan $\delta=0.025$ material, while …
