FEATURED PUBLICATIONS

  • In 5G and 6G, mmWaves bring the promise of new, high bandwidth frequency bands. Propagation losses and fast fading due to increasingly mobile devices and short wavelengths pose challenges for these new concepts. This paper explores the effectiveness of massive MIMO beamforming at mitigating mmWave propagation challenges using Wireless InSite and its mmWave hybrid beamformer capabilities to transmit data streams to a sedan driving in central Manhattan.

  • In this example, a 140 GHz slot antenna array excited by a substrate integrated cavity is demonstrated for use in wireless communications.

  • This paper introduces XFdtd’s transient EM/circuit co-simulation capability, which combines the strength of 3D full-wave electromagnetic simulation with the flexibility of circuit solvers.

  • This example discusses the performance, as simulated by XFdtd EM Simulation Software, of a generic remote camera that provides video surveillance around the house for security monitoring.

  • In this example, a design is evaluated with XFdtd EM Simulation Software, using a conical horn to radiate a lower frequency band at 94 GHz with a tapered dielectric strip to carry the higher band of 340 GHz. The dual-band horn design shows good performance at both frequencies with high gain, symmetrical beams and low sidelobes.

  • Dielectric resonator antennas (DRAs) are a good choice for millimeter wave applications due to their low loss and high efficiency. Designing the resonator for a fundamental mode can be complex due to the small size and sensitivity of the resonator to fabrication errors. In this example, a larger cylindrical dielectric resonator is simulated in XFdtd to show how the excitation of the higher order modes HEM113 and HEM115 can be used to produce wide bandwidth and good gain performance. 

  • Dielectric resonator antennas have numerous characteristics that make them useful, including low loss, high efficiency, and compact size. This example demonstrates how XFdtd analyzes two similar cylindrical dielectric resonator antennas (DRA) which have been developed for dual-polarization performance for different bands. The first antenna is dual-band for covering DCS (1.71-1.88 GHz) and WLAN (2.4-2.48 GHz) bands. The second design is wideband covering the WLAN and parts of the WiMAX band (up to 2.69 GHz).

  • This example demonstrates how XFdtd simulates a 60 GHz cylindrical dielectric resonator antenna that is constructed on a silicon base to emulate on-chip designs. The antenna could be used for a wireless personal area network (WPAN), which would provide communication in the immediate vicinity of a user’s workspace. The antenna has a peak gain of about 2.5 dBi, a bandwidth of over 2.5 GHz, and positive gain of about +/- 55 degrees off boresight.

  • In this example, a circularly polarized dielectric resonator antenna intended for use as part of a compass navigation satellite system (CNSS) is simulated in XFdtd to generate return loss, gain patterns, broadside gain versus frequency, and axial ratio.

  • In this example, Remcom uses XFdtd to demonstrate the performance of a MU-MIMO WiFi routerwith antenna arrays for 2.4, 5, and 6-7 GHz ranges. The maximum coverage possible with different antenna array combinations is discussed to demonstrate the performance capabilities of the device.
