COMBINED PSEUDO SHUNT-FED ZIG-ZAG ANTENNA Russian patent published in 2009 - IPC H01Q19/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering. The antenna is comprised two structures. One structure is big and operates within low-frequency band. The other zig-zag structure is smaller and operates in high-frequency band and acts as shunts within low-frequency band. The zig-zag structure is inside the big structure. Both structures are in the same common plane. Each structure is represented as two rhomboid sections. The rhomboid sections of both structures have unclosed ends. The said ends are directed toward each other. The unclosed ends of the big structure are connected with each other. The unclosed ends of small structure are interconnected via double-wire line. Two sides of each rhomboid section in small structure are connected with double-wire line and made up from shunting conductors. Two other sides of sections are represented as parts of adjacent sides of rhomboid section in big structure. Depending on connection points of shunting conductors, dimensions of rhomboid sections of zigzag structure can be changed and antenna amplification factor can be corrected.

EFFECT: wide bandwidth and increase of antenna amplification factor within high frequency band.
