OSCILLATING AND PASSIVE RIBBON DIPOLES Russian patent published in 1997 - IPC

FIELD: linearly polarized printed antennas; radio communications, television, and phased-out antenna arrays. SUBSTANCE: device has solid dipole on one side of insulating sheet and open section of conductor (stub) on its other end, as well as passive dipole located near them; novelty is that passive dipole is placed at short distance from oscillating dipole and is provided with rather heavy electromagnetic coupling with the former; power feeder conductors are connected to open section of conductor and to dipole. EFFECT: reduced resonant frequency, production of unidirectional radiation, improved radiation efficiency, and reduced size. 4 dwg
