Abstract: An antenna for multi-band communication includes a plurality of radiators which are physically separated from each other. Each radiator is disposed on different planes and is used to jointly function as one or more dipoles. Further, each radiator contributes to resonances at two or more non-overlapping bands. This compact, multi-layered antenna structure is designed for space-efficient operation in multiple frequency bands. It is particularly suitable for portable communication devices with size constraints, as it provides transmit and/or receive capabilities across different bands while occupying minimal space.

Abstract: An antenna is provided. The antenna includes a first radiator positioned at a first level and connected to a ground plane at a second level. In a top view, the first radiator has a first edge, a second edge, a third edge, a fourth edge and a first arc edge. The second edge and the third edge are connected to opposite ends of the first edge. The fourth edge is connected to an end of the third edge opposite to the first edge. The first arc edge with a first radius has opposite ends respectively connected to the second edge and the fourth edge. The first arc edge has a first arc length corresponding to a first central angle, which is less than 90 degrees.
