The latest release of Remcom’s XFdtd® 3D EM simulation software enhances the design tools for 5G mmWave antenna arrays, matching network design and simulation accuracy for higher frequency antennas.
XFdtd provides performance metrics for 5G beam steering applications, including the effective isotropic radiated power (EIRP). By simulating the radiation patterns with the different phasing used to steer the array or subarrays, XFdtd predicts the cumulative distribution function (CDF) of the EIRP of the full array. EIRP is an important quality indicator of an array’s coverage, particularly valuable for analyzing 5G devices supporting multi-user MIMO (MU-MIMO). The CDF of the EIRP is important because carriers are requiring devices to meet stricter quality and performance thresholds, and customers designing mobile devices must compute the gain of many signals propagating in different directions. The new EIRP CDF simulation helps engineers design devices for the demands of 5G. Remcom is at the forefront of this emerging technology.
The matching network design workflow has also been enhanced by expanding XFdtd’s integration with Optenni Lab™ matching circuit optimization software. Optenni’s optimized matching topology data can now be imported into XFdtd, providing users with immediate feedback on circuit behavior and eliminating additional simulations. S-parameters, efficiency and dissipated power are provided for analyzing system performance, which greatly simplifies the matching process for intricate devices with many frequency bands.
This release introduces new modeling options to improve the simulation accuracy for the higher frequency antennas used in the latest-generation devices, including a new feed designed for exciting microstrip, surface current measurement and a user-defined input for the surface roughness of conductors.
