1. A portion of a fuselage of a flying artifact, the portion of the fuselage comprising:
- a conducting surface;
a resonant hole antenna system comprisinga resonant recess formed in the conducting surface, the resonant recess comprising an aperture in the conducting surface, the resonant recess filled at least partially with a dielectric material,a radiating element supported by the dielectric material, the radiating element having a top surface and a perimeter, the radiating element being disposed in the aperture, the top surface being mounted flush with the conducting surface, the perimeter being spaced from an peripheral edge of the aperture by a gap, the gap extending around the perimeter of the radiating element,a feeding element housed in the resonant recess and spaced from the radiating element, the feeding element being electromagnetically coupled with the radiating element for exciting the radiating element with an electromagnetic signal;
wherein the resonant recess comprises a first shape and the radiating element comprises a second shape, the first shape and the second shape being resonant in a predetermined operating frequency.
