| 发明名称 | Stylus and antenna thereof | ||
| 摘要 | A stylus includes a conductive rod, a circuit board, and an antenna. The conductive rod has a first opening. The circuit board is disposed in the conductive rod and includes a ground portion, wherein the conductive rod is electrically connected to the ground portion. The antenna includes a radiating portion and a feeding portion. The feeding portion is electrically connected to the circuit board and extends to the outside of the conductive rod via the first opening. The radiating portion is disposed at the outside of the conductive rod and is electrically connected to the feeding portion. | ||
