    Abstract: Eine elektronische Vorrichtung kann mit einer dielektrischen Deckschicht, einem dielektrischen Substrat und einem phasengesteuerten Antennen-Array auf dem dielektrischen Substrat zum Übertragen von Millimeterwellensignalen durch die dielektrische Deckschicht versehen sein. Das Array kann Leiterbahnen einschließen, die an der dielektrischen Schicht angebracht sind. Die Leiterbahnen können Patch-Elemente oder parasitäre Elemente für das phasengesteuerte Antennen-Array bilden. Die dielektrische Schicht kann eine Dielektrizitätskonstante und eine Dicke aufweisen, die ausgewählt ist, um einen Viertelwellenimpedanzwandler für das Array in einer Betriebswellenlänge des Arrays zu bilden. Das Substrat kann Einzäunungen von leitfähigen Durchkontaktierungen aufweisen, die jede der Antennen innerhalb des Arrays seitlich umgeben. Wenn auf diese Weise konfiguriert, können Signaldämpfung, destruktive Interferenz und die Erzeugung von Oberflächenwellen, die mit der Präsenz der dielektrischen Schicht über dem phasengesteuerten Antennen-Array einhergehen, minimiert werden.

    Abstract: Abstract of the Disclosure An electronic device may have a display in a housing with a metal wall. An antenna may have an antenna ground formed from the wall and an antenna resonating element. Transceiver circuitry may be coupled to an antenna feed that extends between the antenna resonating element and the antenna ground. A return path may extend between the antenna resonating element and the antenna ground in parallel with the feed. The antenna resonating element may have segments that are coupled by a frequency dependent filter. At a first frequency, the filter may have a low impedance so that the antenna resonating element has a first effectively length. At a second frequency that is greater than the first frequency, the filter may have a high impedance so that the antenna resonating element has a second effective length that is shorter than the first effective length.

    Abstract: Abstract of the Disclosure An electronic device may have hybrid antennas that include slot antenna resonating elements formed from slots in a ground plane and planar inverted-F antenna resonating elements. The planar inverted-F antenna resonating elements may each have a planar metal member that overlaps one of the slots. The slot of each slot antenna resonating element may divide the ground plane into first and second portions. A return path and feed may be coupled in parallel between the planar metal member and the first portion of the ground plane. Tunable components such as tunable inductors may be used to tune the hybrid antennas. A tunable inductor may bridge the slot in hybrid antenna, may be coupled between the planar metal member of the planar inverted-F antenna resonating element and the ground plane, or multiple tunable inductors may bridge the slot on opposing sides of the planar inverted-F antenna resonating element.

    Abstract: Abstract of the Disclosure Electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry and antenna structures. A parallel 5 fed loop antenna may be formed from portions of a conductive bezel and a ground plane. The antenna may operate in multiple communications bands. The bezel may surround a peripheral portion of a display that is mounted to the front of an electronic device. The bezel may 10 contain a gap. Antenna feed terminals for the antenna may be located on opposing sides of the gap. A variable capacitor may bridge the gap. An inductive element may bridge the gap and the antenna feed terminals. A switchable inductor may be coupled in parallel with the 15 inductive element. Tunable matching circuitry may be coupled between one of the antenna feed terminals and a conductor in a coaxial cable connecting the transceiver circuitry to the antenna.
