摘要

UAVs are generally an order of magnitude less expensive and smaller than piloted vehicles, but still must possess air vehicle essentials such as propulsion, flight control, and payload. Antennas used for communication, navigation and mission function present unique challenges because they generally cannot be reduced in size without degradation in electrical performance or increase in weight. Typical UAV telemetry systems operate at UHF or L-band frequencies and employ blade antennas that mount on the fuselage exterior and protrude many inches into the air stream. These parasitic antennas degrade aerodynamics, increase drag, increase weight, usually provide less than optimal antenna performance because of blockage by surrounding structure, and are prone to physical damage due to its obstructive locations. These problems can be largely eliminated by embedding antennas into existing composite structures on the UAV, such as wings or stabilizers. Such antennas have been embedded in UAV flight control structures and have demonstrated improved RF performance, lower weight and lower total cost compared to conventional blade antennas. This paper presents results of the antenna demonstration program, including details of the design, integration, manufacture, and electrical test results.
