Abstract
A communication device including a ground plane and an antenna element is provided. An edge of the ground plane is embedded with a notch, which has at least a first edge and a second edge. The antenna element, disposed at the notch, has at least a first operating frequency band and a second operating frequency band. The antenna element includes a first conductive portion and a second conductive portion. The first conductive portion has a starting terminal, electrically coupled to the first edge of the notch through a signal source, as a feeding terminal of the antenna element. A capacitive coupling portion is formed between an end terminal of the first conductive portion and the ground plane. The second conductive portion has a shorting terminal electrically coupled or connected to the second edge of the notch.
