Multiband antenna receiver system with LNA, AMP, combiner, voltage regulator, splitter, noise filter and common single feeder

摘要

An antenna unit and a receiver having such an antenna are disclosed. The antenna includes an antenna body; a first antenna provided on the antenna body for receiving signals transmitted from satellites; at least one second antenna provided on the antenna body for receiving signals transmitted over the earth; a mixer provided in the antenna body for mixing or combining the signals received by the first and second antennas to output the mixed signals as a single output. Further, the receiver includes, in addition to these elements of the antenna unit, a signal separating device for separating the mixed signals into the signal received by the first antenna and the signal received by the second antenna, respectively and then outputting them; and a single cable which connects the mixer and the single separating device to supply the mixed signals thereto. Accordingly, since the antenna unit is provided with the mixer which combines or mixes the received signals and outputs the mixed signals as a single output, only one cable it required to connect the antenna unit to the signal separating device, thereby enabling to reduce the number of cables used for connecting respective antennas with respective corresponding electrical devices.
