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.

Abstract: An apparatus 10 comprises an antenna with a resonant element 76 and a metal electronic device housing 12 that forms an antenna ground element for the antenna. The antenna resonant element 76 is attached by a layer of adhesive 76 to the planar surface of a planar dielectric member 52. The planar dielectric member 52 may be a rectangular transparent display cover glass member with an opaque masking layer of black ink located along a peripheral portion of the said glass member where the antenna resonant element 76 may be adhered. A radio-frequency transceiver and transmission line may be coupled to the antenna. The antenna resonant member 76 and/or the transmission line may be formed by a flexible printed circuit using a polymer sheet substrate. The antenna resonating element 76, possibly backed by a conductive cavity, may be held in position by a biasing structure 78, such as foam, which presses the antenna resonant member 46 towards the inner surface of the display glass 52. The biasing structure may extend between the metal housing and the antenna resonant element. The antenna may be inverted-F antenna.
