EM Simulation of Dual-Band and Wideband Dual-Polarized Cylindrical Dielectric Resonator Antennas for WLAN

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). Both designs are from the paper referenced here, and results presented are a good match to the measurements provided in the paper.
