Product Details
The UWB1400-D is an antipodal Vivaldi antenna covering 1.45 to 8 GHz, a 5.5:1 bandwidth, in a single thin panel. It provides directional radiation patterns and typical end-fire gain of up to 7.5 dBi from a compact, 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 1.45 to 8 GHz (a 5.5:1 bandwidth) in a single directional antenna.
