The current distribution along a passive dipole may significantly differ from the quasi-sinusoidal distribution of a powered dipole with same length, even for thin elements of dipoles, if the length of dipoles corresponds to the full wave length. Moreover, this current distribution depends on the impedance inserted and/or distributed, along the active and especially, the passive dipole. So these inserted concentrated and/or distributed impedances can be used as efficient means to tune the current distribution along the dipoles to more desired forms. Herewith suggested patent presents application of described phenomenon in realization of a new type of Yagi-Uda antenna with full wave dipoles. Described type of antenna is based on utilization of several new technologies and its main features are: high efficiency (low loss), high directivity and its designed construction is much simpler than with Landstorfer Yagi-Uda antenna. New type of antenna is compatible with technology of printed circuit boards (printed antenna), uses no via and is achieved is in a single layer technology.
