COMBINED BROADBAND ZIGZAG ANTENNA Russian patent published in 2007 - IPC H01Q21/30 

FIELD: antenna engineering.

SUBSTANCE: incomplete-zigzag dipole has two identical open triangular loops with additional conductors connected to sides of the latter and is bent along vertical symmetry axis toward antenna directivity forming aperture angle in horizontal plane and three-dimensional structure. Additional conductors are made in the form of semi-arms obtained by setting apart components of complete flat zigzag dipole assembled of two similar rhombic open loops and are mounted between sides of triangular loops to form at least one complete separated zigzag dipole of higher-frequency band connected through junction conductors and two-wire collecting line to power supply points of incomplete zigzag dipole.

EFFECT: enhanced gain and extended operating frequency band.
