Gain, efficiency, impedance, S-parameters, and dissipated power are all common output quantities that are generated. Simulated devices may be excited by an assortment of input options, such as point source voltages and currents or distributed sources including a variety of waveguide ports.

Virtually all aspects of a project may be parameterized, allowing for rapid characterization of design variables. Sophisticated device designs can be created in XFdtd using a full-featured CAD modeler or imported files in many standard formats. Learn more about XFdtd’s High Performance Computing Options for EM simulations. XFdtd simulations are capable of analyzing very complex devices efficiently and are not limited by any computational barriers projects spanning over 500 cubic wavelengths are possible. The vast simulation space covered by XFdtd encompasses traditional antenna designs such as wire antennas, microstrip patches, and horns, as well as newer technologies such as 5G antenna arrays at millimeter wave frequencies, Internet-of-Things (IoT) devices such as smart speakers and cameras, and cutting-edge, next-generation 6G antennas in the terahertz range and beyond. The advanced processing features in XFdtd are also capable of handling fifth generation cellular standards at millimeter wave frequencies that involve antenna arrays and more complex processing.īroad Spectrum of Antenna Analysis ApplicationsĪntenna engineers have long used EM software for optimizing designs virtually, reducing the expense and time of fabricating hardware prototypes while rapidly evaluating numerous device configurations. Our XFdtd 3D Electromagnetic Simulation Software is a full-wave solver based on the Finite-Difference Time-Domain (FDTD) method and is well-suited for analyzing designs ranging from simple dipoles and patches to the latest mobile devices consisting of hundreds of components and multiple antennas. Justin G0KSC has videos, drawings, and photos to assist hams homebrewing antennas.Antennas are ubiquitous in today’s technology and span the spectrum from low frequency, to microwaves, to terahertz and beyond.
