Description

Изобретение относится к радиотехнике и~ может быть использовано для радиосвязи на коротких волнах.The invention relates to radio engineering and ~ can be used for short-wave radio communications.

Известна антенна, содержащая решетку расположенных в одной плоскости симметричных вибраторов разной длины с общей точкой пи- $ тания, плечи которых разнесены одно от другого на равные углы.An antenna is known that contains a lattice of symmetrical vibrators of different lengths located on the same plane with a common power point, the shoulders of which are spaced from one another at equal angles.

Однако известная антенна имеет узкий рабочий диапазон частот.However, the known antenna has a narrow operating frequency range.

Целью изобретения является расширение рабочего диапазона частот.The aim of the invention is to expand the operating frequency range.

Для этого плечи каждого вибратора выполнены в виде геометрически подобных плоских тел, при этом отношения длин соседних вибраторов выбраны одинаковыми и лежат в пределахFor this, the shoulders of each vibrator are made in the form of geometrically similar flat bodies, while the ratios of the lengths of adjacent vibrators are chosen the same and lie within
