Abstract :
Three-dimensional finite-difference time-domain (FDTD) and pseudospectral time-domain (PSTD) algorithms, with perfectly matched layer absorbing boundary condition, are presented for analysis of the newly designed W-band linear tapered slot antenna on rectangular-grooved silicon substrate. Compared to its ungrooved version, the W-band coplanar-waveguide-fed antenna shows significantly improved endfire radiation patterns in the whole band. Also, the symmetric patterns together with moderately high gain, high front-to-back ratio, and low sidelobe level are achieved.
