Antenna tuning in a modular portable communication device

摘要

A system and method of tuning an antenna of a portable device in a modular device system using a device ID associated with second device to tune one or more antennas of a first device. In an embodiment, the first device resolves the device ID of the second device to a set of tuning parameters which improve tuning of the antenna of the first device in the presence of the second device. In a further embodiment, the first device may also tune an antenna of the second device to improve its performance in the presence of the first device.

主权项

1. A portable electronic device, the portable electronic device comprising:
a battery, a memory, a display and an interconnect array to electrically connect the portable electronic device to a second device via physical attachment; a cellular antenna and a WiFi antenna configured to transmit and receive radio frequency (RF) signals; at least one radio frequency (RF) transceiver configured to send an outgoing RF signal to the cellular antenna and the WiFi antenna and to process an incoming RF signal from the cellular antenna or the WiFi antenna; at least one RF tuner connecting the at least one RF transceiver to the cellular antenna and the WiFi antenna; and a controller configured to detect attachment of the second device to the portable electronic device, detect an ID associated with the second device, resolve the detected ID to a set of RF tuning parameters and to configure the at least one RF tuner in accordance with the set of RF tuning parameters for the cellular antenna and the WiFi antenna.
