Abstract
An area-reading antenna (in RF linkage with myriad RF tags) is dynamically tuned. It may be dynamically tuned as to its transmission of a power/clock field, or dynamically tuned as to its transmission of a data signal, or dynamically tuned as to its reception of a data signal, or some combination of all three. In this way, a base station has an improved ability to communicate with a greater fraction of the RF tags within its reading area, despite detuning of individual tags due to proximity of detuning influences such as metal or liquids.
