Abstract

Systems and methods are disclosed for antenna optimization in an information handling system. A portable information handling system includes a chassis and a plurality of antennas coupled to the chassis. The plurality of antennas is capable of communicating in a multiple-input and multiple-output (MIMO) antenna configuration with a wireless-enabled device. The system includes an antenna control module communicatively coupled to the plurality of antennas. The antenna control module is configured to detect a change in at least one of a physical configuration of the chassis and an environment surrounding the portable information handling system, the change affecting a performance one or more of the plurality of antennas. The antenna control module is also configured to, based on the change, update a MIMO antenna list from the plurality of antennas. The MIMO antenna list represents active antennas for communicating with the wireless-enabled device.

determine an interference between one or more of the plurality of antennas based on the angle of the lid relative to the base; and update the MIMO antenna list to avoid the interference.

5 . The system of claim 1 , wherein detecting a change in the environment surrounding the portable information handling system includes determining a degradation in the performance of one or more of the plurality of antennas based on an object in proximity to the chassis.

6 . The system of claim 1 , wherein detecting a change in the environment surrounding the portable information handling system includes receiving a signal from a sensor, the sensor detecting an object in proximity to the chassis.

7 . The system of claim 1 , wherein the antenna control module is further configured to retrain antennas in the MIMO antenna list after updating the MIMO antenna list.

8 . The system of claim 1 , wherein the antenna control module is further configured to account for a power and a data usage of the portable information handling system in updating the MIMO antenna list.
