Cavity Backed Spiral Antennas

Cobham SASL’s ASO-2045 six-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 500 MHz to 4 GHz. This model was designed and developed for applications requiring unit-to-unit amplitude and phase matching, and is an excellent choice for airborne interferometry and direction finding systems. The six-inch diameter by three-inch depth spiral allows close element spacing in arrays to satisfy geometry for upper frequency ambiguity resolution. The ASO-2045 uses a SMA Female connector and has mounting edge for ground plane installation to allow for “clocking” of the elements.
