摘要
The excitation assembly consists of a symmetrical OMT (10) and two splitters (20, 30) respectively connected to two OMT channels. the OMT consists of a cross-connection comprising a central guide (13) and four lateral ports (15, 16, 17, 18) oriented in two directions X, Y, the first distributor (20) consisting of a power input guide (21) operating in a polarization P1 and two output ports (22, 23) coupled to two lateral ports (15, 16), oriented in the X direction, by connection guides (25). , 26) respectively. The first splitter is located on a lateral side of the OMT, orthogonal to the X direction, and its two output ports are arranged one above the other in a side wall of the input guide, the port of upper outlet being placed in front of a first lateral port of the OMT to which it is connected by the first connection guide. The difference in electrical length between the two connection guides is equal to λ / 2.
