Remcom introduces a suite of innovative new tools designed to tackle the changing demands of modern antenna design in the most recent release of XFdtd 3D EM Simulation Software, featuring a phase difference post-processing tool for phased array analysis, enhanced flexibility for far-zone pattern visualization, and significant performance enhancements to streamline workflows.
The standout feature of this update is a new far-zone post-processing tool that allows engineers to compute and display the phase difference between antenna elements. This functionality is crucial for designers of phased arrays utilized in angle of arrival (AoA) estimation for direction-finding systems. With the expanding use of ultra-wideband (UWB) technology for precise indoor localization and tracking, accurately simulating the phase difference of arrival (PDoA) is vital for predicting system performance. By incorporating a phase unwrapping option, XFdtd automatically resolves a key signal processing challenge in PDoA systems, offering engineers clear results comparable to real-world measurements and eliminating a laborious manual correction process.
Furthermore, the far-zone spherical coordinate system can now be repositioned, enabling users to generate 2D pattern cuts along any desired plane. This provides a more detailed approach for evaluating as-installed antenna performance on complex platforms like vehicles and aircraft. By revealing an antenna’s complete 3D radiation characteristics, engineers can assess devices’ real-world performance, such as a smartphone, in various orientations.
To further enhance simulation accuracy, XFdtd now supports waveguide ports with its XACT Accurate Cell Technology conformal meshing feature. XACT is a sub-cellular conformal meshing technique that enables the FDTD solver to represent curved surfaces and intricate geometric features with precision, without requiring an overly fine and computationally intensive grid. Implementing this technology for waveguide ports enhances simulation precision and delivers higher-fidelity outcomes for complex microwave components such as filters and couplers, all while maintaining speed and efficiency.
