摘要
An antenna has a rotating magnetic dipole and a rotating electric dipole having parallel axes of rotation, but orthogonal magnetic and electric vectors. The rotational frequency defines the RF carrier to create the electric and magnetic fields necessary to generate the Poynting vector in the immediate vicinity of the antenna. Because there is no energy required to maintain the fields of a permanent magnet or electret, the only power input is that overcoming mechanical friction, and eddy current and hysteretic losses in adjacent conducting structures.
