Abstract: Embodiments discussed herein refer to systems, methods, and circuits for establishing EHF contactless communications links. The EHF contactless communication link may serve as an alternative to conventional board-to-board and device-to-device connectors. The link may be a low-latency protocol-transparent communication link capable of supporting a range of data rates. The link may be established through a close proximity coupling between devices, each including at least one EHF communication unit. Each EHF unit involved in establishing an EHF communication link may progress through a series of steps before data can be transferred between the devices. These steps may be controlled by one or more state machines that are being implemented in each EHF communication unit.

Abstract: A scalable, high-bandwidth connectivity architecture for portable storage devices and memory modules may utilize EHF communication link chip packages mounted in various two-dimensional and three-dimensional configurations on planar surfaces such as printed circuit boards. Multiple electromagnetic communication links between devices distributed on major faces of card-like devices may be provided with respectively aligned pairs of communication units on each device. Adjacent communication units on a printed circuit board may transmit or receive electromagnetic radiation having different polarization, such as linear or elliptical polarization. Power and communication between communication devices may both be provided wirelessly.

Abstract: An electronic device may include a dielectric substrate, an electronic circuit supported by the substrate, for processing data, and a communication unit having an antenna. The communication unit may be mounted to the substrate in communication with the electronic circuit for converting between a first EHF electromagnetic signal containing digital information and a data signal conducted by the electronic circuit. The electromagnetic signal may be transmitted or received along a signal path by the antenna. An electromagnetic signal guide assembly may include a dielectric element made of a dielectric material disposed proximate the antenna in the signal path. The electromagnetic signal guide may have sides extending along the signal path. A sleeve element may extend around the dielectric element along sides of the dielectric element. The sleeve element may impede transmission of the electromagnetic signal through the sides of the dielectric element.

Abstract: Shielded extremely high frequency (EHF) connector assemblies are disclosed herein. In some embodiments, a first extremely high frequency (EHF) shielded connector assembly configured to be coupled with a second EHF shielded connector assembly. The first EHF connector assembly can include a first EHF communication unit operative to contactlessly communicate EHF signals with a second EHF communication unit included in the second EHF shielded connector assembly. The first connector can include a connector interface that includes a configuration to interface with a respective connector interface of the second EHF shield connector assembly, and several different material compositions that, in conjunction with the configuration, provide shielding to prevent or substantially reduce EHF signal leakage when the first EHF assembly connector is coupled to the second EHF assembly connector and the first EHF communication unit is contactlessly communicating EHF signals with the second EHF communication unit.

Abstract: “Smart” connectors with embedded processors, measurement circuits and control circuits are disclosed for establishing a “contactless” radio frequency (RF) electromagnetic (EM) Extremely High Frequency (EHF) communications link between two electronic devices having host systems. The connectors are capable of monitoring, controlling, and directing (managing) link operation to dynamically adapt to conditions, as well as monitoring and altering (or modifying) data passing through the connector, and selecting a protocol suitable for a communications session. The connectors are capable of identifying the type of content being transferred, providing authentication and security services, and enabling application support for the host systems based on the type of connection or the type of content. The connectors may operate independently of the host systems, and may perform at least one of sensing proximity of a nearby object; detecting a shape of a nearby object; and detecting vibrations.
