Wideband Antennas

In the ever-evolving landscape of electronic warfare and secure communications, next-generation systems demand operation in the 18โ€“40 GHz frequency range and higher. Nuvotronics is at the cutting edge of this evolution, offering cavity-backed spiral and sinuous antennas designed specifically for military airborne applications. Leveraging our proprietary PolyStrataยฎ feed technology, these antennas deliver low-loss, wideband performance in a compact package.

Together, the spiral and sinuous antennas offer numerous options for configuring a wide FOV antenna above 18 GHz. With the spiral, select right or left polarization with 2.92/2.40/1.85 mm connector options. Upgrade to the sinuous antenna โ€” a groundbreaking development โ€” representing the first to industry dual-polarized four-arm antenna in the 18-40 GHz band that occupies the same footprint of a single 0.5โ€ spiral antenna. Both dual-circular and dual-linear polarization options are available.
