    Abstract: An antenna includes a radiator and a balun structure. The radiator includes a first branch for a first current to flow through and a second branch for a second current to flow through. The first branch and the second branch are arranged on two opposite sides of the balun structure. A direction of the first current is at least partially opposite to that of the second current. The first branch is spaced from the balun structure by a first slot. The second branch is spaced from the balun structure by a second slot. The first slot is configured to form a first horizontally-radiated electric field by the first current and a current on the balun structure. The second slot is configured to form a second horizontally-radiated electric field by the second current and the current on the balun structure.

    Abstract: An electronic device comprises a first radiator coupled to a second radiator. One end of a second branch of the second radiator is connected between a head end and a tail end of a first branch of the second radiator. The other end of the second branch is connected between a head end and a tail end of a third branch of the second radiator. A projection of a reference face of the first branch on the first radiator is a first projection. The first projection partly overlaps the first radiator, or a distance between the first projection and the first radiator is within a range of 0 to 3 millimeters. A ratio of a first center distance between an end face of the third branch and the reference face, and a second center distance between the other end face of the third branch and the reference face is within a range of 0.5 to 2.

    Abstract: An antenna structure includes a first signal connector and a second signal connector. The antenna structure further includes a cavity antenna defined by a set of planar walls. The cavity antenna is coupled to the first signal connector and configured to emit a field polarized linearly in a first direction when driven by a signal at the first signal connector. The antenna structure further includes a dipole antenna defined by a pair of arms that are integrated with a wall of the cavity antenna. The dipole antenna is coupled to the second signal connector and configured to a field polarized linearly in a second direction offset from the first direction when driven by a signal at the second signal connector.
