Electronic Devices Having Antennas that Radiate Through Three-Dimensionally Curved Cover Layers

An electronic device having an interior, the electronic device comprising:

• a dielectric cover layer having a three-dimensional curvature about at least one point within the interior of the electronic device;
• a dielectric adapter having a first surface coupled to the dielectric cover layer and a second surface opposite the first surface, wherein the first surface has the three-dimensional curvature;
• an antenna resonating element coupled to the second surface of the dielectric adapter;
• and
• biasing structures that exert a biasing force that presses the antenna resonating element against the dielectric adapter and that presses the dielectric adapter against the dielectric cover layer.

An electronic device having an interior, the electronic device comprising:

• a dielectric antenna carrier;
• an antenna on the dielectric antenna carrier;
• a dielectric adapter having a first surface coupled to the antenna and having an opposing second surface, wherein the second surface has a first non-zero curvature about a first axis extending through the interior of the electronic device, the second surface has a second non-zero curvature about a second axis extending through the interior of the electronic device, and the first axis is oriented at a non-parallel angle with respect to the first axis;
• and
• a dielectric cover layer having an interior surface, wherein the second surface of the dielectric adapter is pressed flush against the interior surface of the dielectric cover layer.
