AMT Microwave Spiral Antennas
Spiral Antennas
AMT offers a wide range of wide band spiral antenna elements and assemblies. Our cavity backed antennas are available in a range of frequencies with focus on 0.5 - 40 GHz. Most of these Spiral Antenna assemblies are offered in amplitude and/or phase matched sets. Efficient design allows for compact sizes and many different mechanical configurations that allow our Spiral Antenna assemblies to be placed on a variety of platforms including military aircraft, marine platforms, and civilian applications.
We are updating our datasheets and tables and they will shortly be available on this site.
