Abstract

Described herein are architectures, platforms and methods for implementing an orientation-agnostic mm-wave antenna(s) that includes an integrated second mechanism on a waveguide structure of the mm-wave antenna. The second mechanism, for example, operates on a second signal and is co-running with an operation of the waveguide structure. The second mechanism may include an audio sub-system such as an audio speaker and/or an audio microphone, or other mechanisms such as a sound or a signal detector, signal transmitter/receiver, or the like.
