Claim 17:
18. A method comprising:
providing a first antenna and a second antenna that are associated with a support structure that comprises a remote communication device that communicates with a vehicle remote communications unit;, transmitting first frequency bands with the first antenna;, transmitting second frequency bands with the second antenna, wherein the second frequency bands are higher than the first frequency bands;
providing a first dual matching network for the first frequency bands that creates a cascade tuning circuit that generates two resonances in an antenna response; and
providing a second dual matching network for the second frequency bands that comprises a second dual band matching circuit comprised of a second set of components to provide two tuning circuits and includes a pi network with first and second branches that present a different impedance for each frequency.
