  • XFdtd Analyzes Complex Beam Steering Antenna Arrays
    characterizing the performance of arrays of antennas for beamforming and beam steering applications. In this article from the July 2020 issue of Microwave Journal, we demonstrate how XF's superposition and array optimization features simplify the process for understanding device performance by providing
  • Simulating a Beam Scanning Substrate Integrated Waveguide Leaky Wave Antenna in XFdtd
    An antenna based on a transverse slotted rectangular waveguide design is realized in a substrate integrated waveguide structure and simulated in XFdtd (R) EM Simulation Software. The antenna scans narrow beams from near broadside to near end fire as a function of frequency. The antenna performance
  • Design & Test a 3D Printed Horn Antenna
    The horn antenna is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves into a beam. 3D printing is a fast-growing technology for rapid prototyping of mechanical structures at a relatively low cost. This enables quick production and demonstrations
  • Beamforming for an 8x8 Planar Phased Patch Antenna Array for 5G at 28 GHz
    An 8x8 planar antenna array creates narrow beams capable of scanning large sectors in front of the antenna. This example focuses on displaying typical simulation results for beams and possible plots of coverage from the full array and combinations of sub-arrays.
  • Analysis of a Terahertz Dual-Band, Dielectric-Loaded Horn Antenna
    radiates the 94 GHz signal while a tapered dielectric block in the center of the structure guides the 340 GHz fields. The antenna has a strong single beam with a peak gain around 18 dBi that is symmetrical in the E and H planes.
  • EM Simulation of 28 GHz Series-Fed Patch Antenna Array for 5G
    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
  • Nano Connections in Phased Array Beam Forming of Laser and Antenna Systems
    Information collection and transmission systems are undergoing significant upgrades to accommodate the need for focused higher transmission speeds and massively increased digital information.
  • A 5G, 60 GHz Antenna Array for use with mmWave Wireless Virtual Reality Headsets
    A 60 GHz antenna array design is simulated in XFdtd to demonstrate suitability for use on wireless Virtual Reality headsets. The antenna array is comprised of elements each containing two patches and a parasitic element. The resulting array produces a fan beam which may be steered by varying
