Abstract
An electronic device may have multiple near-field communications antennas. Multiplexer circuitry may have a transceiver port that is coupled to a near-field communications transceiver, and multiple antenna ports coupled to respective near-field communications antennas. Non-near-field communications antennas may be used by non-near-field communications circuitry. The electronic device may have a housing with opposing first and second ends and a display. One of the near-field communications antennas and one of the non-near-field communications antenna may be formed from shared antenna structures at the first end. Another of the near-field communications antennas and another of the non-near-field communications antennas may be formed from shared antenna structures at the second end. An additional near field communications antenna may be overlapped by the display.
