Transforming Antenna Design with Remcom

Remcom, a leader in electromagnetic simulation software, has made significant advancements in antenna design with its latest release of XFdtd® 3D EM Simulation Software. The new update focuses on addressing the contemporary challenges faced by engineers in the field of antenna technology, particularly as the demand for ultra-wideband (UWB) applications grows.

Key Features of the New Release

Among the suite of innovative tools introduced, the highlight is a phase difference post-processing tool. This feature allows engineers to accurately compute and visualize the phase difference between antenna elements, a critical capability for those designing phased arrays used in angle of arrival (AoA) estimation for direction-finding systems. The ability to accurately simulate phase difference of arrival (PDoA) is increasingly vital due to the burgeoning applications of UWB technology in indoor localization and tracking systems.

To enhance the user experience, XFdtd now includes a phase unwrapping option that automatically resolves a common signal processing issue in PDoA systems. This functionality produces results that are unambiguous and more closely aligned with real-world measurements, alleviating the need for a time-consuming manual correction process.

Additionally, the far-zone spherical coordinate system has been upgraded, allowing users to reorient it to generate 2D pattern cuts along any specified plane. This feature provides engineers with a refined method to analyze antenna performance on complex platforms, such as vehicles and aircraft. With these new capabilities, users can gain insights into an antenna's full 3D radiation characteristics, enabling them to evaluate real-world device performance, for instance, how a smartphone operates when held in various orientations.

Another notable enhancement is the support for waveguide ports through the application of XACT Accurate Cell Technology®, a conformal meshing technique that offers high precision on curved surfaces and intricate geometrical features without necessitating a computationally intensive grid. This improvement facilitates higher accuracy and more reliable results in simulating complex microwave components like filters and couplers, without sacrificing overall speed and efficiency.

Supporting Advanced Engineering

“The cornerstone of the XFdtd roadmap is to support engineers who are designing increasingly detailed and crowded devices with accurate, reliable simulation software that predicts behavior in the real world,” said Sam Seidel, the product manager for XFdtd. He emphasized that features like the phase difference tool are essential in helping their customers adapt to rapidly evolving technologies like UWB, ultimately accelerating their time to market while offering trustworthy insights into device performance.
