Full Wave Matching Circuit Optimization in XFdtd ® Determining the final set of component values in a matching network can be a challenging process. Traditionally, RF engineers have had to simplify and idealize their matching circuits in schematics that are separated from the EM simulation. This simplification into a lumped element schematic requires perfect grounds and leaves out the coupling and transmission line effects of the interconnect metal and the antennas. XFdtd’s Circuit Element Optimizer Simplifies and Speeds the Process of Matching the Antenna XF’s Circuit Element Optimizer determines lumped element component values based on the following goals: Radiation efficiency
