Claim 17:
18. An electronic device comprising:
a substrate;
a first dielectric resonating element having a first proximal end mounted to a surface of the substrate and having a first distal end opposite the first proximal end, the first dielectric resonating element being configured to radiate in a first frequency band, wherein the first dielectric resonating element comprises a first dielectric column and a first feed probe on a surface of the first dielectric column, the first dielectric column having dimensions that are configured, upon excitation by the first feed probe, to establish one or more electromagnetic modes that cause the first dielectric resonating element to radiate in the first frequency band;
a second dielectric resonating element having a second proximal end mounted to the surface of the substrate and having a second distal end opposite the second proximal end, the second dielectric resonating element being configured to radiate in a second frequency band at frequencies greater than the first frequency band and the second dielectric resonating element being offset from the first dielectric resonating element, wherein the second dielectric resonating element comprises a second dielectric column and a second feed probe on a surface of the second dielectric column, the second dielectric column having dimensions that are configured, upon excitation by the second feed probe, to establish one or more electromagnetic modes that cause the second dielectric resonating element to radiate in the second frequency band;
a first conductive cap on the first distal end of the first dielectric resonating element, the first conductive cap being configured to adjust a boundary condition of the one or more electromagnetic modes of the first dielectric resonating element; and
a second conductive cap on the second distal end of the second dielectric resonating element, the second conductive cap being configured to adjust a boundary condition of the one or more electromagnetic modes of the second dielectric resonating element.
