Abstract
The disclosure provides a communication device including a ground plane, an antenna and an extended grounding structure. The ground plane has a first side and a second side opposite to each other. The antenna is disposed at the first side and has a first feeding end. The extended grounding structure is disposed at the second side and includes a connection portion and a symmetrical structure. The symmetrical structure is electrically connected to the ground plane via the connection portion, wherein the symmetrical structure is symmetrical along a symmetry axis, and an extension line of the symmetry axis passes through the first side and the second side. The disclosure can effectively prevent antenna efficiency from being degraded due to an insufficient size of the ground plane, so as to significantly enhance communication quality.
