Abstract: An electronic device may be provided with a display and wireless circuits. The wireless circuits may include antenna structures and radio-frequency transceiver circuitry that transmits and receives radio-frequency signals using the antenna structures. A ground plane for the antenna structures may be located in the center of the electronic device under the display. A resonating element may be used to reduce signal interference that otherwise arises when simultaneously operating the display and the antenna structures. The resonating element may be implemented using an L-shaped structure have an arm that extends parallel to one of the edges of the display.

Abstract: An electronic device may contain clock circuits, transmitters, and other circuits that serve as sources of noise signals. The noise signals may be characterized by a noise spectrum. The noise spectrum produced by a noise source can be adjusted by adjusting spread spectrum clock circuitry in a clock circuit, by adjusting data scrambling circuitry in a transmitter circuit, or by making other dynamic adjustments to the circuitry of the electronic device. During operation of the electronic device, sensitive circuitry in the device such as wireless receiver circuitry may be adversely affected by the presence of noise from a noise source in the device. Based on information such as which receiver bands and/or channels are being actively received and target sensitivity levels for the receiver circuitry, control circuitry within the electronic device can determine in real time how to minimize interference between the noise source and the wireless receiver circuitry.
