Zusammenfassung:This invention relates generally to vehicle electronic components which communicate in the electromagnetic spectrum. More particularly, this invention relates to a single vehicle antenna system which receives signals for a plurality of electronic components which operate in different spaced apart frequency bands. An antenna system includes a diplexer connected to at least two vehicle electronic components which communicate through signals in spaced apart frequency bands. The antenna is coupled to the diplexer at a common branch. The radio is connected to a first equipment branch of the diplexer by a first transmission line and the RKE system is connected to a second equipment branch of the diplexer unit by a second transmission line. In a preferred embodiment, the first transmission line is of a length equal to one forth the wavelength of the second signal, while the second transmission line is of a length equal to one forth the wavelength of the first signal. Accordingly, by relating the length of the first and second transmission lines, each operates as a short in relation to the signal carried by the other which substantially eliminates attenuation.
