A single aperture antenna fed by N parallel strip lines

A single aperture antenna with N parallel equally spaced strip lines (probes), constructed using a triplate transmission (TT)-line, has been analysed using the FDTD method. The analysis is classified into two cases: (1) an infinite size case, where the upper and lower conducting plates of the TT-line are of infinite extent; and (2) a finite size case, where the upper and lower conducting plates are of finite extent.
