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.

Communication device with extended grounding structure to enhance antenna performance

A dipole array antenna includes a plurality of antenna units including a first radiator and a second radiator. The first radiator includes first and second arms extending toward a first direction, the second radiator includes third and fourth arms extending toward an opposite of the first direction. A first current route of the first radiator includes a first direct trace extending from the first transmission line toward at least a quarter of the first arm and the second arm, and a first meandering trace extending from the first direct trace to at most three quarters of the first arm and the second arm. A second current route of the second radiator includes a second direct trace and a second meandering trace with similar layout as the first current route of the first radiator.
