Electronic device with near-field antennas

摘要

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.

主权项

1. An electronic device, comprising:
a first near-field communications loop antenna; a second near-field communications loop antenna; near-field communications circuitry that wirelessly communicates using the first and second near-field communications loop antennas; an antenna ground; and an inverted-F antenna resonating element, wherein the first near-field communications loop antenna includes a portion of the inverted-F antenna resonating element and a portion of the antenna ground.
