  • XFdtd Simulation Of A Millimeter Wave, Wideband Dielectric Resonator Antenna

    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. 

  • Wi-Fi Chipset/Device Characterization And Compliance Testing

    Characterization and compliance testing of Wi-Fi chipsets and devices is complex and involves significant challenges for design and test engineers. The new Synchronized Independent Gate mode eliminates the need to make these compromises by enabling packet power measurements on multiple synchronous or asynchronous transmit chains across multiple power sensors. The combination of the new measurement capability and the industry leading performance specifications allows the Boonton RTP Series of RF power sensors an ideal solution to characterize today’s advanced Wi-Fi chipsets and devices. 

  • 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).

  • XFdtd Simulation Of A mmWave On-Chip Cylindrical Dielectric Resonator Antenna For WPAN

    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.
