The invention relates to a low-profile conformal antenna, which comprises a feed network, a dielectric substrate, a metal sheet and a metal back cavity plate which are fixedly connected in a layered manner in sequence. The overall low-profile conformal antenna is in an arc-shaped lath form; the profile height is 1/30-1/50 of wavelength of the center frequency of the low-profile conformal antenna and is much less than those of a waveguide slot antenna and a microstrip patch; and the requirement of a modern carrier on low air resistance is met. The feed network comprises an input end and at least four output ends; at least four radiating slots are evenly distributed in the metal sheet; at least four cavities are evenly distributed on one side surface of the metal back cavity plate; and a coaxial feed joint is arranged at the middle part of the other side surface of the metal back cavity plate. More than two low-profile conformal antennas are connected in parallel to form a low-profile conformal antenna array. T
