Full wave matching circuit optimization (FW-MCO) is a new technology that combines full wave, 3D EM simulation with circuit optimization into a novel approach for solving an age-old RF problem: determining which component values provide the desired match for a given matching network layout. This article describes the design process using the design of a matching circuit for a GPS-Bluetooth antenna.
XF’s Circuit Element Optimizer utilizes full wave analysis to select the component values for a given printed circuit board (PCB) layout. The tool allows design engineers to optimize matching circuit lumped element values directly in the EM layout where the coupling from multiple antennas and the ground return current paths are taken into account. This whitepaper gives an overview of how the Circuit Element Optimizer works and the benefits it provides.
This whitepaper demonstrates how XFdtd's time-domain approach enables rapid development by allowing engineers to determine the performance of a fully detailed sensor model installed behind a piece of fascia without needing to build prototypes and run tests in an anechoic chamber. The analysis of a 25 GHz sensor frames the discussion.
With XFdtd, there is no limit to the resources you can exploit to solve your EM calculations. This report quantifies the performance profile of XF's GPU and MPI technologies. We demonstrate the pros and cons of different combinations of equipment and techniques, including cost considerations for those researching available hardware.
The design of a matched antenna is a fairly involved process. This webinar shows how XFdtd simplifies this process by providing tools to parameterize the unmatched antenna, determine S11, synthesize a matching network topology with Optenni Lab, and determine the final component values using the Circuit Element Optimizer.
Remcom’s Circuit Element Optimizer for XFdtd is a unique tool for full wave matching circuit optimization. This webinar introduces the capability and provides an example of how it is used. A GPS/Bluetooth antenna and an LTE antenna are used for the demonstration.
