1. An antenna for multiple wireless services, comprising:
a disk-shaped dielectric substrate with a first 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 first surface defining a plurality of lobes configured to be disposed in respective ones of the plurality of pockets and having a second surface defining an outer rim and a 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;
a plurality of MIMO feed lines providing external connection to respective lobes, wherein the MIMO radiator body and the radiator ring provide a substantially 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 over the central shelf configured for one of the wireless services other than the respective wireless services of the MIMO radiator body.
