  1. A 5G, 60 GHz Antenna Array For Use With mmWave Wireless Virtual Reality Headsets
    5/13/2019

    This example demonstrates an antenna array for 5G 60 GHz applications of wireless communication for wearable devices such as virtual reality headsets. The antenna design for this example is from the paper by Hong and Choi of Hanyang University. The array is composed of four elements which each have two patches and a parasitic element. The parasitic element aids in producing a wider beam in one dimension to give better coverage. The beams may be steered by varying the phase shift between elements to provide near hemispherical coverage.

  2. Design And Simulation Of 28 GHz Beamforming System And Antenna Array For 5G Network Base Stations
    4/18/2019

    This example describes a more developed 28 GHz antenna array capable of forming multiple beams for use in applications such as 5G network base stations. The system consists of three parts: a Rotman lens beamformer with seven input ports and eight output ports, a series of stripline Wilkinson power dividers to split each Rotman output into eight equal signals, and an 8x8 patch antenna array. The design process consists of three separate stages. This example will describe the creation of each stage of the device and evaluate the performance of the individual stages and the full device.

    Wireless power transfer is an emerging technology used in many applications, including consumer electronics, electric vehicles, and biomedical implants, and will undoubtedly see continued growth over the next decade and beyond.  This presentation demonstrates how XFdtd can be used to simulate and analyze wireless charging systems.

  5. White Paper: Modeling RF Propagation In Mines Using Wireless InSite
    12/12/2018

    This paper presents results from modeling RF propagation in a mine using Wireless InSite®. The Edgar Mine in Idaho Springs, CO provided the realistic scenario for the model. The path loss exponent was evaluated for a 5m section of the modeled mine by considering three different materials and three different standard deviation of surface roughness values for dry granite. When comparing this simulated data with data retrieved from the Edgar Mine it was determined that the Uniform Theory of Diffraction (UTD) ray tracing code, of Wireless InSite, can portray a communications system within a mine environment.

  6. White Paper: Complex 3D Modeling Of Sea To Land Scenario
    12/12/2018

    This paper presents results from sea to land propagation using Wireless InSite®. The effort explores the effects of various elements in the scene and how they impact the results. The various elements in the scene include the ships out at sea, the ships docked, the docks themselves, the buildings around the dock area, and the material properties of each.

    11/30/2018

    WaveFarer™ is a high-fidelity radar simulator for drive scenario modeling at frequencies up to and beyond 79 GHz. Near-field propagation and scattering methods compute raw radar returns from target objects while considering multi-path interactions from ground reflections and other structures.

  8. Benefits Of Time-Domain Electromagnetic Simulation For Automotive Radar
    11/6/2018

    The requirements for automotive radar sensors in common ranges - such as 24 GHz and 77 GHz - are becoming more stringent and engineers need to understand how design decisions affect performance.  

  9. 5G/4G Combined Antenna Analysis In A Smartphone Using EM Simulation
    10/17/2018

    This example uses XFdtd EM Simulation Software to analyze the performance and interaction of two antenna systems operating at 4G (860 MHz) and 5G (28 GHz) in close proximity in a smartphone design. 

  10. EM Simulation Of 28 GHz Series-Fed Patch Antenna Array For 5G
    8/17/2018

    Series-fed patch elements forming an array are simulated to demonstrate antenna performance and beamforming including S-parameters, gain, and effective isotropic radiated power (EIRP) at 28 GHz. Beam steering is performed in one plane by adjusting the phasing at the input ports to each of eight elements.
