Abstract: An electronic device may be provided with a liquid crystal polymer (LCP) printed circuit having conductive trace and a hole. A conductive flange may be soldered to the conductive trace and may extend into the hole. The end of the conductive flange may laterally surround a central opening within the hole. A conductive contact may be inserted into the central opening. Solder may be deposited over the conductive flange and in the central opening. The solder may couple the conductive contact to the conductive flange and thus the conductive trace. This may ensure a robust mechanical and electrical connection between the conductive contact and the conductive trace on the printed circuit despite the printed circuit being formed from LCP, which may not support copper-plated through vias for coupling to the conductive contact.

Abstract: An electronic device may be provided with peripheral conductive housing structures having a segment that forms a resonating element for an antenna. A speaker may be mounted to a mid-chassis of the electronic device. A printed circuit may be mounted to the speaker and may have a ground trace for the antenna. A conductive spring may extend through the printed circuit and the speaker to couple the ground trace to the mid-chassis. A conductive contact pad may be welded to an aluminum layer such as an aluminum layer used to form the mid-chassis. A conductive spring such as the conductive spring coupled to the ground traces may press against the contact pad. The contact pad may include gold or nickel-plated stainless steel. The contact pad may provide a strong electrical connection between the conductive spring and the aluminum layer.

Abstract: An electronic device may be provided with a sensor module and an antenna having an antenna arm, ground structures, and a tuner. The tuner may be mounted to a printed circuit overlapping the sensor module. A spring may be mounted to the printed circuit and may couple the tuner to a conductive chassis of the sensor module. The sensor module may include optical sensors that gather sensor data through a display and may form ground paths from the tuner to the ground structures. Conductive interconnect structures such as springs may exert biasing forces in different directions to couple the ground paths to different layers of the ground structures. This may serve to couple the antenna to the ground structures as close as possible to the tuner, thereby maximizing antenna performance, despite the presence of the sensor module.

Abstract: An electronic device may have a display. A display cover layer and a transparent inner display member may overlap a display pixel layer. The display pixel layer may have an array of display pixels for displaying images for a user. A touch sensor layer may be interposed between the display pixel layer and the transparent display member. A ferromagnetic shielding layer may be mounted below the display pixel layer. A flexible printed circuit containing coils of metal signal lines that form a near-field communications loop antenna may be interposed between the ferromagnetic shielding layer and the display pixel layer. A non-near-field antenna such as an inverted-F antenna may have a resonating element mounted on an inner surface of the display cover layer. The resonating element may be interposed between the transparent display member and the display cover layer.

Abstract: A device with near-field communications (NFC) capabilities is provided. A housing may include first and second segments and a support plate separated from the segments by a slot. A first inductor may be coupled between the first segment and the plate. A second inductor may be coupled between the second segment and the plate. A transceiver may have a first signal terminal coupled to the first segment over a first path and a second signal terminal coupled to the second segment over a second path. The transceiver may convey differential signals in an NFC band over a loop path for an NFC antenna that includes the first conductive path, the first segment, the first inductor, a portion of the plate between the first and second inductors, the second inductor, the second segment, and the second conductive path. This may optimize wireless performance and volume for the NFC antenna.

Abstract: An electronic device may be provided with wireless circuitry. The wireless circuitry may include antenna structures such as an antenna resonating element arm and an antenna ground. A split return path may be coupled between the antenna resonating element arm and the antenna ground. The antenna structures may form one or more inverted-F antennas when operated at non-near-field communications frequencies. The antenna structures may be coupled to near-field communications transceiver circuitry using a conductive path. When operated at near-field communications frequencies, near-field communications signals may be conveyed using the conductive path, the antenna resonating element arm, the return path, and the antenna ground. A capacitor may be coupled between the conductive path and an antenna ground. The capacitor may short non-near-field communications signals to the antenna ground and block near-field communications signals from passing from the conductive path to the antenna ground.
