FRAME AERIAL Russian patent published in 2009 - IPC H01Q7/04 

FIELD: radio engineering.

SUBSTANCE: proposed device comprises three orthogonal frames with feeders connected thereto. One frame is arranged vertically with its axis aligned with axis of symmetry of two other vertical mutually perpendicular frames. Note here that horizontal frame is placed above aforesaid horizontal frames and separated, by breaks, into four equal parts, symmetric to vertical frame planes. Aforesaid brakes include four horizontal symmetric line sections electrically interconnected at the center either in series or in parallel. Output feeder of horizontal frame represents a symmetric line section arranged along the axis of symmetry of horizontal frames.

EFFECT: higher efficiency.
