XFdtd Simulation Of A Millimeter Wave, Wideband Dielectric Resonator Antenna
3/5/2021
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.

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).

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.
