Abstract

The invention relates to wave transmission-reception techniques. The antenna forming the subject of the invention is of the type comprising a waveguide radiator 1 in the walls of which are made transmitter slots 4 and which is connected to a high-frequency channel 6, and is characterised in that the waveguide radiator 1 is formed of two waveguides 2, 3 with transmitter slots 4, these guides penetrating into one another so as together to form a cruciform cross-section, the entrance of the waveguide radiator 1 being connected by a supply connector 5 to the high-frequency channel 6. The invention can be used in particular in radio systems employed for steering the movements of agricultural machines. <IMAGE>

Description

Изобретение относится к антенной технике и может быть использовано на подвижных транспортных средствах.The invention relates to antenna technology and can be used on mobile vehicles.

Цель изобретения — упрощение конструкции при формировании всенаправленной диаграммы направленности в плоскости, перпендикулярной продольной оси.The purpose of the invention is to simplify the design in the formation of an omnidirectional radiation pattern in a plane perpendicular to the longitudinal axis.

На .чертеже представлена структурная схема антенны.The drawing shows a block diagram of the antenna.

Антенна содержит волноводный излучатель 1, имеющий поперечное сечение крестообразной формы, в узких стенках которого выполнены излучающие щели 2, плавные переходы 3, щелевой мост 4, имеющий первый вход 5, второй вход 6 и выходы 7 и 8.The antenna contains a waveguide emitter 1, having a cross-section of a cruciform shape, in the narrow walls of which radiating slots 2 are made, smooth transitions 3, a slot-hole bridge 4, having a first input 5, a second input 6 and exits 7 and 8.

Антенна работает следующим образом.The antenna works as follows.

В режиме передачи сигнал поступает от генератора на первый вход · 5 щелевогоIn the transfer mode, the signal comes from the generator to the first input · 5 slot

моста 4, при' этом на его выходах 7 и 8 получаются сигналы, равные по амплитуде и сдвинутые по фазе на π/2.bridge 4, with this at its outputs 7 and 8 signals are obtained equal in amplitude and shifted in phase by π / 2.

В результате возбуждения излучающих щелей 2 равноамплитудными квадратурными сигналами в дальнейшей зоне антенны распределение поля в плоскости, перпендикулярной продольной оси антенны, получается равномерным, т.е. формируется всенаправленная диаграмма направленности.As a result of the excitation of the radiating slots 2 with equal amplitude quadrature signals in the further zone of the antenna, the field distribution in the plane perpendicular to the longitudinal axis of the antenna is uniform, i.e. an omnidirectional radiation pattern is formed.

При работе на прием обеспечивается возможность приема с постоянным коэффициентом усиления при любом направлении прихода сигнала.When working at the reception provides the possibility of receiving a constant gain in any direction of arrival of the signal.

Работа антенны на прием и передачу осуществляется без ферритового циркулятора, т.е. обеспечиваются простота конструкции, уменьшение потерь, высокая надежность.The operation of the antenna for receiving and transmitting is carried out without a ferrite circulator, i.e. simplicity of design, reduction of losses, high reliability.
