Claim 8:
9. 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, wherein the lobes are joined in an Alford loop configuration;
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 covering transmission or reception over a plurality of terrestrial wireless bands for respective wireless services; and
at least one low-profile radiator disposed in the sunken central shelf configured for one of the wireless services other than the respective wireless services of the MIMO radiator body.
