dbDIRECT Broadband Vivaldi Antenna


The dbDIRECT Broadband Antenna features broad frequency range of operation, high gain, small form factor and directional radiation pattern, making it highly attractive for widespread use in test and measurement of emerging wireless technology devices and radars. Contrary to conventional vivaldi antennas limited to operating only at higher frequencies, the dbDIRECT Broadband Antenna design is optimized to operate at a frequency as low as 700 MHz up to 6 GHz. This lightweight and compact antenna design provides excellent matching over a broad frequency range.

The antenna is designed to be placed in a DVTest portable anechoic chamber such as the dbSAFE enclosures for OTA (Over the Air) testing of DUTs. The antennas can be mounted in fixed positions to facilitate repeatable results. When used in conjunction with a rotary positioning mechanism, customers are able to detect the highest point of power sensitivity for enhanced accuracy and repeatability in measurements. In this configuration both the antennas and DUTs can be positioned in order to facilitate the measurement.

Application:

  • RF wireless device testing in Anechoic chambers where directional and high gain link required with DUT
  • 3G, 4G,5G and 5G new radio (5G NR), Carrier aggregation, MIMO
  • LTE, LTE-A, WIMAX, WiFi, Bluetooth, GPS, GSM, Z-Wave, LoRa
  • Spectrum Analysis in DAS environment, radars, IoT
