Description

(54) УСТРОЙСТВО СВЯЗИ ПРЯМОУГОЛЬНОГО ВОЛНОВОДА С КРУГЛЫМ ВОЛНОВОДОМ(54) DEVICE OF COMMUNICATION OF RECTANGULAR WAVEGULL WITH ROUND WAVEGULL

с одного конца отрезка 2 волновода, а его другой конец св зан с согласованной нагрузкой .from one end of the waveguide section 2, and its other end is connected to a matched load.

В момент нахождени  электромагнитной волны типа TEoi или ТЕо в отрезке 2 волновода круглого поперечного сечени  через отверсти  3 св зи в отрезке 1 волновода пр моугольного поперечного сечени  возбуждаетс  волна типа Г юРассто ние d между центрами отверстий 3 св зи выбираетс  таким образом, что исключаетс  распространение обратной волны .When an electromagnetic wave of the type TEoi or TEO is located in section 2 of a circular cross-section waveguide, through connection holes 3 in section 1 of a rectangular cross-section waveguide, a type G wave is excited. The distance d between the centers of the communication holes 3 is selected so that propagation of the inverse is avoided. the waves.

Диаметр отверстий 3 св зи и рассто ние d между их центрами выбираетс  в завис мости от числа отверстий св зи, определ емого длиной св зи, дл  обеспечени  требуемого ослаблени  между отрезком 1 волновода пр моугольного поперечного сечени  и отрезком 2 волновода круглого поперечного сечени .The diameter of the communication holes 3 and the distance d between their centers are chosen depending on the number of communication holes determined by the length of the connection to provide the required attenuation between section 1 of the rectangular waveguide 1 and section 2 of the circular cross section.

В отрезке 2 волновода круглого поперечного сечени  дл  волны типа TEoi отверсти  3 св зи имеют диаметр 1,62 мм, а рассто ние d между их центрами составл ет 2,86 мм; дл  волны типа ТЕо2 диаметр отверстий 3 св зи равен 1,7 мм, а рассто ние d составл ет 2,84 мм, при этом внутренний диаметр отрезка 2 волновода составл ет 10 мм и 18,4 мм соответственно дл  волн типа TEoi и ТЕо2 в полосе частот 40-50 Ггц, что позвол ет улучшить выделение указанных типов волн.In section 2 of a waveguide of circular cross section for a wave of the type TEoi, the communication apertures 3 have a diameter of 1.62 mm and the distance d between their centers is 2.86 mm; for the TEo2 wave, the diameter of the communication holes 3 is 1.7 mm, and the distance d is 2.84 mm, while the inner diameter of the waveguide segment 2 is 10 mm and 18.4 mm, respectively, for the TEoi and TEo2 waves frequency band 40-50 GHz, which allows to improve the allocation of these types of waves.

Дуга сектора круга поперечного сечени  металлического вкладыша 4 дл  волны типа TEoi в области св зи равна 60° (фиг. 5), а дл  волны ТЕо2-90° (фиг. 6).The arc of a sector of a circle of a cross section of a metal insert 4 for a TEoi type wave in the communication region is 60 ° (Fig. 5), and for TEO2-90 ° (Fig. 6).

Металлический вкладыш 4 ослабл ет магнитные волны типов ТМ и электрические волны иных типов, чем волн типа Tfoi и ТЕо2, радиальными составл ющими электрического пол , причем ослабление составл ет более, чем на 20 дБ.The metallic insert 4 attenuates magnetic waves of the TM types and electric waves of other types than the Tfoi and TEo2 types, the radial components of the electric field, the attenuation being more than 20 dB.
