UWB-1 Vivaldi Antenna Nuevo

UWB-1

The design of the "tapered slot" antenna (TSA, aka Vivaldi antenna) was presented by Peter Gibson in 1979. The benefit of this antenna is it's extremely large bandwidth and very simple construction. Due to the exponentially widening of the slot a gradual transformation of impedance is achieved, with very simple geometrical figures at the base of the slot, the feed can be transformed and matched to the required impdance. For details please see the Wikipedia article on Vivaldi antennas.

TSA antennas are either constructed (etched) as a PCB or cut from sheet metal. The UWB-1 is made of solid aluminium sheet metal, the rear end is angled and can be used as a bracket for installation of the antenna. The connector is an SMA female socket, which is the usual connector for microwave applications. The usable frequency range is 430 MHz to 6 GHz for the 9dBi model, and 600 to 6000 MHz for the 13 dBi model. These frequencies cover all services in the UHF and SHF range (GSM, DECT, LTE, Wifi, Wimax, ADS-B, Radar and much more). This makes this antena very well suited for spectrum monitoring with an SDR or a classical spectrum analyser. But also specialised applications like ground penetrating radar or EMC lab measurements are typical applications for such an antenna.

The UWB antenna has a relatively flat SWR response over the entire frequency range, for model UWB-1 the gain is approx. 9 dBi at the center, and 12 dBi for model UWB-2. Each antenna is adjusted individually, a VSWR measurement documentation is included with the antenna. The bracket at the rear of the antenna is suitable to use a 38mm U bolt (not included) for installation on a mast or tripod. The UWB antennas are not intended for permanent outdoor use.
