Abstract:
A vehicle navigational receiver module, comprising:a first planar antenna configured to receive navigational radio signals; a first signal processing circuit connected to the first planar antenna; a second planar antenna configured to receive telematic radio signals, the second planar antenna arranged so as to at least partially overlap the first planar antenna; a second signal processing circuit that is connected to the second planar antenna; a common connector configured to output the navigational radio signals and input/output the telematic signals, navigational radio signals and telematic radio signals being transmitted in different frequency ranges via the common connector; wherein a DC component of one of the navigational radio signals and the telematic radio signals applied at the common connector functions as a power source for the first signal processing circuit and the second signal processing circuit, and a control signal for switching over a signal processing circuit of the telematic signal between the transmitting and the receiving modes is transmitted in a further frequency range via the common connector.
