Before revision: Conformal antennas were developed in the 1980s as avionics antennas embedded in the curving skin of military aircraft, replacing conventional antenna designs which project from the aircraft surface, in order to reduce aerodynamic drag.
After revision: Conformal antennas were developed in the 1980s as avionics antennas integrated into the curving skin of military aircraft, replacing conventional antenna designs which project from the aircraft surface, in order to reduce aerodynamic drag.
