Claim 16:
17. An automotive antenna system for multiple wireless services, comprising:
a disk-shaped dielectric substrate with an upper surface defining an annular ledge and a central recess with a plurality of pockets;
a disk-shaped MIMO radiator body disposed in the central recess having a lower surface defining a plurality of lobes configured to be disposed in respective ones of the plurality of pockets and having an upper surface defining an outer rim and a sunken central shelf;
a radiator ring disposed at the annular ledge so that the radiator ring and the outer rim converge along an annular gap therebetween, wherein the dielectric substrate, MIMO radiator body, and radiator ring function as an RF lens array with a horizontally-directed radiation pattern adapted for reception and transmission of terrestrial signal radiation for at least a first wireless service; and
at least one low-profile radiator disposed in the sunken central shelf providing a substantially circularly polarized or vertically-directed radiation pattern for at least a second wireless service.
