Abstract
Apparatus and techniques can include a planar antenna that can include a folded conductive strip portion coupled to a driven node of a wireless communication circuit, the folded conductive strip portion comprising at least two segments laterally offset from each other and at least partially laterally overlapping with each other, and a first region oriented along a first axis in a plane of the planar antenna and a second region oriented along a second axis in the plane of the planar antenna, the two axes and the two regions specified to provide polarization diversity of radiation from the planar antenna. The planar antenna can include a stub coupled to the folded conductive strip portion, the stub configured to provide a first specified operating frequency range at or near resonance using a mode corresponding to a total physical path length along the folded conductive strip portion.
