COMBINED DOUBLE FOLDED DIPOLE ANTENNA Russian patent published in 2010 - IPC H01Q21/30 

FIELD: physics; radio.

SUBSTANCE: invention relates to antenna technology. According to the invention, the combined double folded dipole antenna contains three integrated antennae. One antenna is an incomplete zig-zag dipole consisting of two identical open triangular frames. The triangular frames lie in a single vertical plane one on top of the other and they are connected to each other with formation of array feed points. This dipole operates in the low-frequency metre wavelength range. The other two antennae are folded dipoles. The folded dipole is made in form of a flat rectangular figure. Each folded dipole adjoins the corresponding base of the triangular frame of the incomplete zig-zag dipole. The base of each triangular frame serves as a side of the corresponding folded dipole at the same time. There is an opening in the side of the folded dipole lying opposite the base of the frame. The opening is ended by feed points of the folded dipoles. These feed points are connected crosswise to array feed points through connecting lines.

EFFECT: increased amplification constant.
