Abstract

The conformal finite-difference time-domain (CFDTD) method is applied to characterize the dual elliptically tapered antipodal slot antenna (DETASA) for UWB applications. DETASA antenna consists of the metallization on two sides of the substrate and presented by two polygons. The CFDTD method with uniaxial perfectly match layer is suitable to model the patch with curved surface and edges of these polygons. This paper demonstrates the capability of this simulation method for UWB antenna design. This method is examined with experimental approach.
