Parallel plate slot coupler modeling using two dimensional frequency domain transmission line matrix method

A slot coupler for coupling between via-defined waveguides is analyzed using the 2D frequency domain transmission line matrix (2D-TLM) method. The general 2D-TLM model for a slot coupling between parallel plate waveguides is useful in the design of advanced low cost millimeter-wave packaging. The via waveguide coupler is modeled and the model verified by comparison to measurement.
