Abstract (en)
[origin: CA1194946A] . A pivoting joint connects two rectangular waveguides, connecting transmission-reception equipment on board a satellite to an antenna, which is only opened out when the satellite has been placed in orbit. These waveguides comprise a fixed section and a moving section, pivoting about the longitudinal axis common to the two sections. They issue or open out in facing manner on two parallel planar faces separated by a nonzero distance, but which is very small compared with the wavelength. One of these faces has a quarter wave trap ensuring the radio seal of the joint. An abutment defines the position in which the two guides are in an extension of one another. When the satellite reaches orbit, antenna is opened out and the joint pivots to this position.
