Abstract

3-D FDTD simulation of a planar broadband Ka-band (25-35 GHz) antipodal linearly-tapered slot antenna (ALTSA) and experimental measurements are presented. The Berenger matched layer absorbing boundary condition (PML-abc) is used for the FDTD computation. A printed ALTSA has been realized by using the RT/Duroid PCB substrate. Good agreement between simulation and measurement is achieved
