Adaptive direction control of multiple antenna used for radio frequency communication such as Bluetooth (RTM)

摘要

The system has two HF units [RF1,RF2] configured for the Bluetooth (RTM) standard and these communicate base band signals to a base band unit [BBT]. A number of antenna [AN1-AN6] connect with a direction control unit [PHS] having control inputs from a unit [PST] responding to the base band signals. Optimum antenna directions for each frequency group are determined based on measured parameters.
