1. An apparatus for wireless communication, comprising:
- a first antenna array comprising a first plurality of antenna elements in a first planar configuration and adapted to send and receive wireless signals in a first frequency range, wherein at least one of the first plurality of antenna elements comprises a microstrip patch antenna that comprises a first patch element and a second patch element parasitically coupled to the first patch element;
a second antenna array comprising a second plurality of antenna elements in a second planar configuration and adapted to send and receive wireless signals in a second frequency range, the second frequency range being different from the first frequency range; and
a configuration wherein the first and second antenna arrays together comprise a dual aperture antenna array.

Abstract
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).
