Hyper frequency electronically scanned antenna e.g. wireless point to point communication antenna, feeding splitter for masthead of ship, has body delimiting cavity with higher dimension, and absorbing unit placed at upper end wall of body

摘要

The splitter (10) has a ring shaped hollow body (14) including an upper end wall (20) and a lower end wall and delimiting an elongated rectangular sectioned electromagnetic field propagation cavity whose dimension is higher than wavelength of utilized hyperfrequencies. The body has coaxial inlets (24) and coaxial outlets (26) connected near respective smaller sides of the cavity, where the inlets and the outlets are formed by subminiature version A (SMA) type connectors. An absorbing unit is placed at the upper end wall of the body.
