Abstract
An electronic device and its stylus pen having an FM antenna functionality are provided. The stylus pen includes a pen tip, a penholder, and a metal element spirally surrounding the penholder from a first end portion to a second end portion of the penholder. The pen tip is made of conductive material, the penholder is made of insulated material, and at least one end portion of the metal element is electrically coupled to the pen tip. When the pen tip is inserted into an antenna jack defined in the electronic device, the metal element of the stylus pen is electrically coupled via the pen tip to a radio receiving circuit arranged inside the electronic device. The metal element is thereby enabled to act as an FM antenna and is enabled to receive wireless signals from the radio receiving circuit and transmit wireless signals to the radio receiving circuit.
