NAWCWD China Lake and Pt. Mugu are seeking an L/S/C telemetry system for the F/A-18 Super Hornet. Toyon Research Corporation is under contract to design, fabricate, and deliver flush-mount antennas in support of the Navy's L/S/C telemetry effort. The telemetry antenna is approximately 5 inches in diameter and recesses into the aircraft about 4 inches. It covers the L band (1435-1535MHz), the S band (2200-2400MHz), and the C bands (4400-4900MHz, 5100-5150MHz, 6100-6700MHz). The patterns of the antenna resemble those of a blade or monopole antenna. The telemetry antenna is located on a panel on the nose section of the aircraft fuselage and a flush-mount L1/L2/L5 GNSS antenna is co-located on the same panel. The pair of antennas require a notch filter at the L1 GPS frequency to avoid self-jamming from the L band telemetry signals to the GPS receiver. The notch filter and telemetry electronics are being fabricated by other aerospace contractors. Toyon has fabricated the antennas and characterized them in an anechoic chamber. The antennas have also been tested against environmental conditions required for flight approval on the F/A-18 Super Hornet. The telemetry antenna can easily be redesigned for other platforms.
