Abstract: Conduit structures for redirecting extremely high frequency (EHF) signals are disclosed herein. The conduit structures discussed herein are designed to re-direct EHF or RF signal energy from a first signal path to a second signal path. The conduit structures according to embodiments discussed herein can re-direct the RF signal energy while simultaneously adhering to specified signaling characteristic of the RF signal and minimizing stray RF signal radiation within a device to support device-to-device contactless communications.

Abstract: 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.

Abstract: 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.
