    • A compact parametric antenna (CPA) employs the principle of stimulating an electric field E and a magnetic field H for synthesis of an electromagnetic wavefront according to the Poynting vector theory S=E .times.H. The CPA includes a dielectric, magnetically-active, open circuit mass core, ampere windings around the mass core and an RF source for driving the windings to produce an electromagnetic wavefront. The principle behind the synthesis of a electromagnetic wavefront is that the RF current source provides a sinusoidal RF current I.sub.0 which drives the ampere windings to stimulate an external electric field E and, through the induction of gyromagnetic, gyroscopic and Faraday effects in the dielectric, magnetically-active, open circuit mass core, an external magnetic field H having an internal magnetic flux density B. The configurations and dimensions of CPAs can be readily engineered such that CPAs can replace the many different types of conventional antennas presently utilized in a wide range of communication applications including tactical and global radio communication, television broadcasts, cellular telephone networks, computer WANs and the like.
