  1. EM Simulation Of Dual-Band and Wideband Dual-Polarized Cylindrical Dielectric Resonator Antennas For WLAN 3/1/2021

    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).

  2. XFdtd Simulation Of A mmWave On-Chip Cylindrical Dielectric Resonator Antenna For WPAN 3/1/2021

    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.

  6. 60 GHz Phased Array Antenna Design Using XFdtd For WiGig Application Presentation 9/16/2020

    In this presentation, Remcom discusses analyzing and optimizing an aperture coupled 1x4 patch antenna array with a compact, fan-shaped feeding network for operation in 60 GHz band using Remcom’s full-wave electromagnetic simulation product, XFdtd. We also demonstrate superposition and antenna array optimization. The superposition simulation provides a means for checking the performance of individual elements in an array, each with a different input power and phase. The array optimization feature allows users to estimate the excitation for each element in the array for a specified EIRP. Further, the total spatial coverage of designed phased arrays will be accurately estimated.
