Product Details
The UWB700-D is an antipodal Vivaldi antenna covering 700 MHz to 8 GHz, an 11:1 bandwidth, in a single thin panel. It provides directional radiation patterns and typical end-fire gain of up to 8 dBi from a lightweight FR-4 board under a quarter-inch thick, making it an easy, low-cost addition to a test bench, mast, or enclosure. It is well suited to software-defined radio, wideband sensing and monitoring, electronic warfare and signals intelligence, direction finding, and university research.
- Antipodal Vivaldi covering 700 MHz to 8 GHz (an 11:1 bandwidth) in a single directional antenna.
- Typical end-fire gain of 8 dBi with directional radiation patterns; VSWR typically below 2.5:1 across the band.
- Thin, lightweight FR-4 board (7.4 × 7.9 in, under 0.25 in thick including the SMA connector).
- Linearly polarized, 50 Ω, SMA female, ideal for SDR, monitoring, and direction finding.
- Versatile across SDR, EW and SIGINT, direction finding, cellular / WiFi / LoRa / IoT, and radar and university research.
- Typical performance data (.txt) available for download.
