Claim 13:
14. An electronic device comprising:
peripheral conductive housing structures that run around a periphery of the device;
a display mounted to the peripheral conductive housing structures;
a dielectric layer mounted to the peripheral conductive housing structures opposite the display;
a substrate;
a dielectric resonator antenna having a dielectric column mounted to the substrate, wherein the dielectric column has a first surface at the substrate, the dielectric column has a second surface that opposes the first surface, the dielectric resonator antenna is configured to convey radio-frequency signals at a frequency through the dielectric layer, and the dielectric resonator antenna has a feed probe coupled to the dielectric column and configured to excite the dielectric column to radiate at the frequency; and
a conductive patch on the second surface of the dielectric column and separated from the feed probe by a portion of the dielectric column, the conductive patch being configured to adjust a boundary condition of one or more electromagnetic modes that cause the dielectric resonator antenna to radiate at the frequency.
