Abstract
An EM emitter includes at least three orthogonal coils driven by an oscillating voltage source, with the coils being electrically in parallel or series. When used in a vehicle, particularly an airplane, and the vehicle is lost, e.g., sinks, the emitter's EM signal passes through water with little attenuation and can be detected and the vehicle located.
Claims16
An emitter comprising:
- three planar surfaces, each of the planar surfaces including a coil, the coils being orthogonal to each other;
- and
- an oscillating voltage source connecting the coils in parallel or in series;
- at least one printed circuit board forming at least one of said planar surfaces;
- wherein at least one of said three orthogonal coils is formed as a spiral on said at least one printed circuit board;
- and
- wherein at least one of the planar surfaces includes a hole therethrough, with the coil on that at least one of the planar surfaces being centered at said hole.
