Methods, systems, and apparatuses are described for wireless communication using the mmW spectrum. In particular, antenna structures may include arrays of antenna elements to deal with line-of-sight issues. Further, antenna structures may be configured to produce a beam (e.g., signal) that is relatively narrow and has a relatively high gain to deal with losses, such as mentioned above. Still further, antenna structures may be configured to provide beam steering (e.g., beamforming) capability. Such antenna structures may be designed to be relatively compact to deal with the limited real estate available on modern wireless communication devices (e.g., cellular telephones).
