WIDE-BAND SHORT-WAVE ZENITH-RADIATION ANTENNA Russian patent published in 2004 - IPC

FIELD: antenna engineering; mobile radio centers of short-wave communication systems.

SUBSTANCE: antenna sheet is horizontally mounted and attached to tops of four vertical masts at height h; antenna wires forming square sides are halved and mechanically joined together at points where they cross insulators. These halves of wires are interconnected in pairs by means of two additional sheets incorporating at least two wires and passed through geometric center of square wherein antenna power supply points are disposed. Two adjusting components are arranged in diagonals of two small squares formed by wire halves and additional sheets. Rectangular reflector disposed in vertical plane crossing zero potential points has its vertical sides of height h/3 forming masts and horizontal ones are made of antenna wire. This reflector is provided with circuit lying directly on ground.

EFFECT: enhanced directivity factor of antenna in zenith direction.
