Abstract
A radio communication system for a vehicle includes a first radio unit to communicate using a first channel within a designated radio frequency band, a second radio unit to communicate using a second channel within the designated radio frequency band, a common receive antenna shared by the first and second radio units, a signal splitter having a splitter input port coupled to the antenna, a first splitter output port, and a second splitter output port, a first circulator, and a second circulator. The first circulator has an input port coupled to the first splitter output port, an output port coupled to the first radio unit, and a termination port coupled to a matched load. The second circulator has an input port coupled to the second splitter output port, an output port coupled to the second radio unit, and a termination port coupled to a second matched load.
