Spheroidal Multi-Solenoid Antenna

A spheroidal antenna, having a spheroidally configured winding. The winding comprises a three-dimensional spiral about an axis with the radius of turns of the winding progressively increasing and then decreasing. The winding may be of a multi-solenoid conductor. It may also be composite, having a primary conductor with a secondary conductor wound toroidally about the primary conductor. The antenna may have a plurality of windings. Two windings may be in the same layer, with the turns thereof being laterally adjacent each other. The antenna may be multi-layered, with the turns of one layer being at an angle to the turns of a super-adjacent layer. The antenna may have a hollow spheroidal former.
