Abstract
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.
Claims20
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;
- at least one 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 at least one antenna and to process an incoming RF signal from the at least one antenna;
- at least one RF tuner connecting the at least one RF transceiver to the at least one 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.
A method of tuning at least one antenna of a portable electronic device when a second device is physically attached to the portable electronic device, the at least one antenna having at least one associated tuner, the method comprising:
- detecting physical attachment of the second device to the portable electronic device;
- detecting an ID associated with the second device;
- resolving the detected ID to a set of RF tuning parameters;
- and
- configuring the at least one RF tuner in accordance with the set of RF tuning parameters.
A modular portable device system comprising a first portable electronic device and a second portable electronic device, wherein the first portable device includes an interconnect array to electrically connect the first portable electronic device to a second portable electronic device when the second portable electronic device is physically attached to the first portable electronic device, an antenna, a radio frequency (RF) transceiver, an RF tuner connecting the at least one RF transceiver to the at least one antenna, and a controller configured to detect physical attachment of the second portable electronic device to the first 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.
