Multiband Antenna System for Tactical Aircraft.
Abstract
The ability to extend the frequency range of a 100 MHz to 40 MHz antenna to include the 30 MHz to 100 MHz range was examined through analysis and testing. Antenna impedance, patterns, power handling and gain comparison measurements were made over the extended frequency range. The measurement were made on full scale as well as fifth and quarter scale models. Results show that it is possible to construct an antenna that will radiate from 30 MHz to 400 MHz effectively without the need for active tuning. A single input connector to the antenna is used. A mechanical design study was performed to demonstrate the feasibility of locating this antenna in the vertical stabilizer of the F-4 and F-18 aircraft. In the case of the F-4, retrofit possibilities were investigated and a flyable fincap antenna was fabricated. The results of the mechanical study showed that it is feasible to use the antenna in the F-4 and F-18 as well as other Navy aircraft including the AV-8. (Author)
