Abstract
Exemplary embodiments are provided of apparatus and methods relating to antenna multiplexers and demultiplexers are disclosed. In exemplary embodiments, antenna multiplexers include two or more inputs for receiving a corresponding number of signals from multiple antennas. The antennas may include world cell antennas, AM/FM antennas, SDARS antennas, GPS antennas, and/or antennas combining the preceding. Exemplary antenna multiplexers also include an output for simultaneously outputting the combined signals received by the multiplexer. Demultiplexers for receiving such combined signals and outputting each signal via a separate output are also disclosed.
