Description
Известны антенные снстемы, предназначенные дл работы в УКВ диапазоне и состо щие из четырех сннфазно включенных направленных антенн, размещенных в верщпнах пр моугольника, одна нз сторон которого расноложена нараллельно земной поверхности.Antenna circuits are known that are designed to operate in the VHF band and consist of four directional antennas that are four phase-wise, located in the vertices of a rectangle, one of which is located on a parallel surface of the earth.
Недостаток подобных антенных спстем состоит в значительном уровне напр женности боковых лепесткоз в вертикальной п горизонтальной плоскост х, что приводит к снижению коэффициента усилени антеииы и не дает возможности обеспечить однонаправленность ее действи .The lack of such antenna systems consists in a significant level of intensity of the side lobe in the vertical and horizontal planes, which leads to a decrease in the anteiia gain factor and makes it impossible to ensure unidirectionality of its action.
Отличительна особенность описываемой антенной системы состоит в том, что антенны размещены в вершинах ромба, одна нз диагонале которого расположена нерпенд :кул рно земной поверхности.A distinctive feature of the described antenna system is that the antennas are placed at the tops of a rhombus, one of which has a nerpend located in its diagonal: it is cool on the earth's surface.
Индивидуальные антенны могут быть выполнены в виде простых вибраторов с рефлекторами, в виде антенн типа «волновой канал н т. д.Individual antennas can be made in the form of simple vibrators with reflectors, in the form of wave channel type antennas, etc.
Размещение антенн в вершинах ромба производ т так, чтобы либо больща , либо меньша диагональ была бы располол ена перпендикул рно к земной поверхности.Antenna placement at the tops of the rhombus is made so that either a larger or smaller diagonal is perpendicular to the earth's surface.
При таком размещении антенн удаетс обеспечить подавление боковых лепестков не менее чем на 14 дб по сравнению с главным. Угол раствора главного лепестка при этом не измен етс . Изменение вертикального размера описываемой антенной системы не оказывает вли ни на диаграмму ианравленности в горизонтальной нлоскости, однако дает возможность формировать диаграмму направленности во взаимно-периендпкул рныл плсскост х незав:1симо друг от друга.With this arrangement of antennas, it is possible to provide side lobe suppression of not less than 14 dB compared to the main one. The angle of the main lobe solution does not change. A change in the vertical size of the described antenna system does not affect the diagram and the alignment in the horizontal plane, however, it makes it possible to form a radiation pattern in the mutual periennefractive direction without any distance: 1 from each other.
Предмет изобретени Subject invention
Антенна система, работающа в УКВ диапазоне и состо ща из четырех синфазно включенных направленных антеии, отличающа е тем, что, с целью снижени уровн напр жеииости боковых лепестков в вертикальной и горизонтальных плоскост х, антенны размещены в вершинах ромба, одна из диагоналей которого расположена перпендикул рно земной поверхности.Antenna system operating in the VHF range and consisting of four in-phase directional directed anthias, characterized in that, in order to reduce the tension level of the side lobes in the vertical and horizontal planes, the antennas are placed in the tops of the rhombus, one of the diagonals of which is perpendicular rno the earth's surface.
