COMPUTER INPUT STYLUS WITH MULTIPLE ANTENNAS

摘要

The present disclosure provides a stylus for enabling inputs to be made to a host electronic device. The stylus has multiple antennas that are displaced from each other and the tip of the stylus body. In operation, the antennas are excited to each radiate an electromagnetic field directed towards the tip of the stylus. The radiated electromagnetic fields may be sensed by the host electronic device to determine the position of the tip relative to a sensing surface.
