Abstract: Antenna structures or an electronic device 10 comprise conductive members of a resonant antenna element where parasitic coupling 336 is present. The parasitic coupling 336 may be between a second antenna 40W resonating element 306 and a first antenna 40F resonating element 108 and/or an inductor 214 of a split return path from a first antenna element 108 to a ground member 104 terminals 204. The antenna structures may comprise multiple antennas which may include an inverted- F antenna as a first antenna 40F element and an additional antenna as a second antenna 40W resonating element. The antenna elements may be formed from portions of the peripheral conductive electronic device housing structure present at either end of a device 10, including, for example, a display bezel. A conductive portion of a device’s display may be used to form at least a portion of an antenna ground member. Impedance matching circuitry may be used within the antenna structures. The second antenna 40W may be formed in a cut-out region of a ground member 104. The structures may be formed from various metals and dielectric materials and may provide a compact, efficient and detuning resistant antenna for electronic devices.

Abstract: Antenna structures at a given end of an electronic device may include antenna structures that are shared between multiple antennas. The device may include an antenna with an inverted-F antenna resonating element formed from portions of a peripheral conductive electronic device housing structure and may have an antenna ground that is separated from the antenna resonating element by a gap. A short circuit path may bridge the gap. The short circuit path may be a split return path coupled between a first point on the inverted-F antenna resonating element arm and second and third points on the antenna ground. The electronic device may include an additional antenna that includes the antenna ground and metal traces that form an antenna resonating element arm. The antenna resonating element arm of the additional antenna may be parasitically coupled to the inverted-F antenna resonating element and a portion of the split return path.
