wall-mounted or flush-mounted flat antenna for satellite television

摘要

wall-mounted or flush-mounted flat antenna for satellite television, comprising a coaxial input line (11), a power splitter, n coaxial output lines and antenna array of n (1311, 1312, 1313 .. 131n) antenna units, where n is an integer greater than or equal to unity, and wherein the coaxial input line and the coaxial output line both, an inner conductor and an outer conductor, and wherein the coaxial input line and the coaxial output line both, a connecting said power splitter and a mating end of the external devices, which have signal end, and wherein the antenna unit (1311, 1312, 1313 .. 131n) is a signal input end, and wherein the power splitter includes an inner space, an input-side metal wall on the side of the inner space and an output-side metal wall with respect to the input-side metal wall on the other side of the inner space, and wherein a medium in the inner space is filled, characterized in that the outer conductor to the connecting end of the coaxial input line to the input-side metal wall of the power splitter is connected, and wherein the inner conductor, the end of the coaxial input line by the inner space of the power splitter, and on the output-side metal wall of the power splitter is connected, and wherein the signal input end each antenna unit (1311, 1312, 1313 .. 131n) with the inner conductors on the connecting end of a coaxial output lines is connected to and the inner space of said power splitter, and the metal wall of the power splitter is connected, and wherein the outer conductor at the connecting end of all of the coaxial output lines is potential-free hovers.
