Methods, systems, and apparatus for using antennas for millimeter wave contactless communication. One of the apparatuses is a communication device that includes a transducer configured to convert electrical signals into extremely high frequency (EHF) electromagnetic signals, the EHF electromagnetic signals substantially emitted from a first surface of the communication device, wherein the transducer is positioned on a substrate of the communication device, and an integrated circuit coupled to the substrate, wherein the transducer includes multiple parallel resonant antenna elements in an array.

Antennas for millimeter wave contactless communications

Embodiments discussed herein refer to systems and structures for focusing dispersal of electromagnetic signals. Focusing of the electromagnetic signals is achieved by a reflective lens that is constructed from several extremely high frequency focusing layers. Each focusing layer can include an extremely high frequency focusing window that, collectively, define the geometry of a cavity backed reflective lens and its ability to focus electromagnetic signal dispersion.

Electromagnetic signal focusing structures

Conduit structures for guiding extremely high frequency (EHF) signals are disclosed herein. The conduit structures can include EHF containment channels that define EHF signal pathways through which EHF signal energy is directed. The conduit structures can minimize or eliminate crosstalk among adjacent paths within a device and across devices. Launch structures that interface with waveguides are also disclosed herein. Launch structures can control the EHF interface impedance between a contactless communication unit and the waveguide. Waveguide structures discussed herein are designed to provide maximum bandwidth with minimal jitter over a desired distance.
