Remcom has announced a suite of new tools designed to address the evolving challenges of modern antenna design in the latest release of XFdtd® 3D EM Simulation Software, including a phase difference post-processing tool for phased array analysis, enhanced flexibility for far-zone pattern visualization, and significant performance improvements to expedite workflows.
The highlight of the release is a new far-zone post-processing tool that enables engineers to calculate and plot the phase difference between antenna elements. This capability is critical for designers of phased arrays used in angle of arrival (AoA) estimation for direction-finding systems. With the rapid growth of ultra-wideband (UWB) technology for high-precision indoor localization and tracking, the ability to accurately simulate phase difference of arrival (PDoA) is essential for predicting system performance. By including a phase unwrapping option, XFdtd aims to automatically resolve a key signal processing challenge in PDoA systems, providing engineers with unambiguous results that are comparable to real-world measurements and eliminating a time-consuming manual correction step.
