Abstract : The patent describes a ferrite rod positioned between two parallel foil conductor strips. The strips terminate in perpendicular tabs which form a half-wavelength dipole antenna. Electromagnetic energy is coupled from free space to the ferrite rod by the dipole tabs. The energy propagates down the rod until reflected by a short circuit section connecting the ends of the conductor strips, opposite the tabs. After reflection, the energy propagates in a reverse direction. A coil carrying high frequency A.C. modulates the phase of the energy during propagation in both directions through the ferrite. When the energy is reflected back to the dipole tabs, the phase modulated energy is radiated to free space.
