ANTENNAS MOUNTED UNDER DIELECTRIC PLATES
First Claim
1. An electronic device, comprising:
- a display having a transparent planar display member through which the display presents images;
a patterned opaque masking layer on an inner surface of the transparent planar display member, wherein the patterned opaque masking layer is located along a peripheral portion of the transparent planar display member; and
an antenna having an antenna resonating element; and
adhesive that is interposed between the antenna resonating element and the patterned opaque masking layer and that adheres the antenna resonating element to the inner surface.

Abstract
Electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry and antenna structures. The antenna structures may include antennas such as inverted-F antennas that contain antenna resonating elements and antenna ground elements. Antenna resonating elements may be formed from patterned conductive traces on substrates such as flex circuit substrates. Antenna ground elements may be formed from conductive device structures such as metal housing walls. Support and biasing structures such as dielectric support members and layer of foam may be used to support and bias antenna resonating elements against planar device structures. The planar device structures against which the antenna resonating elements are biased may be planar dielectric members such as transparent layers of display cover glass or other planar structures. Adhesive may be interposed between the planar structures and the antenna resonating elements.
