XFdtd’s schematic editor provides the capability to connect two voltage sources to a single antenna, improving workflow efficiency for diplex matched antenna use cases. System and radiation efficiencies can be effortlessly computed from a single schematic for two operating modes. This tutorial demonstrates XF's workflow for evaluating a diplex matched antenna and analyzing two different matching network states simultaneously.
The antenna in this workflow example is a dual-band antenna designed for the GPS L1 band and the 2.4 GHz WiFi band containing channels 1 - 14. First, the characteristic impedance of the antenna is determined via an FDTD simulation and then a matching network is evaluated to see the matched performance of delivered power.
