Abstract
An information handling system stylus transmits a wireless signal at a writing tip to enhance touch detection of the writing tip by a touchscreen display and receives wireless signals from the touchscreen display at a receiving antenna. To enhance control of wireless energy distributed at the writing tip, the receiving antenna is selectively coupled to the writing tip, such as by transitioning from a float of the receiving antenna to an interface with the stylus power source at transmit by the writing tip. Charge at the receiving antenna helps to shape the energy distribution from the writing tip, such as to match the energy distribution of other styluses in use at the touchscreen display.
