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: The invention provides an antenna for multi-broadband and multi-polarization communication, which may include a plurality of radiators configured to jointly function as one or more dipoles, and a plurality of parasitic elements. Each radiator may be configured to contribute to resonances at two or more nonoverlapping bands, and may comprise an arm and a ground wall connecting the arm and a ground plane. The arm may comprise an arm plate and a folded arm. The ground wall may comprise a meandering portion causing a distance between the arm and the ground plane to be shorter than a length of a current conduction path along the ground wall between the arm and the ground plane. On a geometric reference surface, a projection of each parasitic element may extend between two gaps which clamp a projection of an associated one of the radiators.
