An improved dipole antenna having unbalanced radio frequency current in
spiral radiating elements operating on a plurality of resonant
frequencies providing a wide range of impedance matching to a device
feeding radio frequency energy to said antenna. Said dipole antenna is
also configured with parasitic spiral elements to provide increased
operational performance. Each said spiral radiating element electrical
parameter enabling said element to be operated alone. Said dipole antenna
operates on any portion of the radio frequency spectrum.
