Embedded antennas in aerostructures and electrically short conformal antennas
A mobile platform communication system includes one or more HF antennas disposed in the surface of the mobile platform. The HF antenna may comprise one or more mesh screens. Alternatively, or in addition, the HF antennas may comprise characteristic mode transducers to excite metallic features on the mobile platform skin. The mobile platform skin includes a lightning strike protection layer that is disposed within the mobile platform skin around in internal surface of the antenna such that the antenna does not distend the mobile platform skin and increase drag.
1. A mobile platform comprising:
one or more high-frequency antenna panels disposed in a body panel of the mobile platform; and
a lightning arresting layer disposed in the body panel configured to allow the one or more high-frequency panels to radiate while maintaining a lightning protection system's integrity,
wherein:
the one or more high-frequency antenna panels are disposed to be flush with an exterior surface of the body panel;
the one or more high-frequency antenna panels are configured and disposed for high-frequency near vertical incident skywave communication; and
the lightning arresting layer is configured to transit from a first depth proximal to the exterior surface to a second, lower depth beneath the one or more high-frequency antenna panels.
2. The mobile platform of claim 1 , wherein at least one of the one or more high-frequency antenna panels are configured for circular polarization.
3. The mobile platform of claim 1 , wherein each of the at least of the one or more high-frequency antenna panels is configured to operate in tandem with at least one other of the at least one of the one or more high-frequency antenna panels.

communicate beyond line-of-site via high-frequency near vertical incident skywave; and
induce an Eigen mode resonance in a metallic skin of the mobile platform; and
wherein the lightning arresting layer is configured to transit from a first depth proximal to an exterior surface of the one or more body panels to a second, lower depth beneath the common mode transducers.
