Abstract
A system of antennas, each having disparity operating frequencies, are incorporated into the same aircraft body panels. HF antennas define loops with large internal areas; additional higher frequency antennas are disposed within that large internal area. The higher frequency antennas are sufficiently different so as to prevent coupling. Antennas operating in the same frequency range, disposed on different parallel surfaces are operated in concert as a steerable array.
