Datasheet: ASO-2154 Series Cavity Backed Spiral Antennas

Cobham Sensor Systems' ASO-2154 two-inch diameter spiral antennas provide superior performance for use in applications requiring circular polarization. With excellent input VSWR, these antennas provide smooth broadband gain, low axial ratios, and consistent pattern performance over 2 - 18 GHz. This model was designed and developed for applications requiring extremely close unit-to-unit phase matching, and is an excellent choice for airborne interferometry and direction finding systems. Two-inch diameter spirals allow close element spacing in arrays for better system performance. ASO-2154 is available with SMA Female connector.
