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 a housing and an antenna having a resonating element. The resonating element may have first and second arms extending from opposing sides of a feed. The first arm and a portion of the housing may radiate in a cellular ultra-high band. The first arm may have a fundamental mode that radiates in a first ultra-wideband (UWB) communications band at 6.5 GHz. The second arm may have a fundamental mode that radiates in a 5.0 GHz wireless local area network band. The first and second arms may have a harmonic mode that radiates in a second UWB communications band at 8.0 GHz. The antenna may convey radio-frequency signals in each of these communications bands without the need for adjusting components in the antenna to switch between the UWB communications bands.
