Synthesis of conformal HF and VHF directional arrays on spherical bodies using surface resonator techniques

A new technique involving the use of low-profile surface resonators that are similar to microstrip patch antennas and are conformal with the body surface is investigated. It is shown that the proposed technique offers good control over radiation patterns and takes full advantage of the directivity available from a body of a given size, while avoiding either significant interference with the interior of the body or large protrusions. The technique is expected to find application in narrow band systems on vehicles where a low-profile system is desirable, e.g., for spacecraft telemetry and remotely piloted vehicles.
