Differential capacitive antenna ports coexistence in wireless capacitive signal reception and transmission systems and/or wireless capacitive power supply transmission systems

Abstract

The invention relates to the field of electronic communication systems. More specifically, the invention relates to antenna devices (ports) for high-speed, short-range, capacitive wireless devices that can be used for stream data and power supply transmission between two adjacent electronic devices, modules, etc. The differential capacitive antenna ports for the wireless capacitive signal reception and transmission, comprise a capacitive transmission port configured to generate electric fields that represent transmitted signals with at least one pair of transmitting terminals, with conductive working surfaces connected to the port inputs at the input feed points, and a capacitive reception port configured to detect electrical fields that represent transmitted signals with at least one pair of receiving terminals, with conductive working surfaces connected to the port outputs at the output feed points where terminals' conductive working surfaces of capacitive ports are positioned to ensure that the conditional straight line crossing the middle of the working surfaces of at least one pair of receiving terminals is approximately perpendicular to the conditional straight line passing through the middle of the working surfaces of at least one pair of transmitting terminals, or that the conditional straight line passing through the output feed points from the working surfaces of at least one pair of receiving terminals is approximately perpendicular to the conditional straight line passing through the input feed points to the working surfaces of at least one pair of transmitting terminals. Differential capacitive antenna ports for the wireless capacitive signal reception and transmission are also configured for a wireless capacitive power supply reception and transmission, both by means of a separate channel and without it.

technical field [0001] The present invention relates to the field of electronic communication systems. More specifically, the present invention relates to antenna devices (ports) for high-speed, short-range, capacitive wireless devices that can be used for communications between two adjacent electronic devices, modules, etc. Streaming data (streaming data) and power transmission. Background technique [0002] Unlike conventional radio systems, wireless communication between multiple electronic devices or multiple blocks of an electronic system can be efficiently implemented by means of capacitive coupling, i.e., sending analog and digital signals at close distances (millimeter or centimeter distance) Signal. Recently, due to the advent of more sophisticated manufacturing processes for semiconductor chips and modern electronic components that have become faster and more suitable for making practical circuits for wireless capacitive coupling devices, Capacitively coupled de...

Problems solved by technology

[0005] A significant disadvantage of known capacitive systems, methods and devices is that they do not address the creation of capacitive devices that can integrate in one solution all capabilities similar to those of modern high-speed wire-serial differential interfaces and power transmission lines. complex task of the interface

In this sense, one of the known problems is that the co-existing transmitting device and receiving device and the parasitic interference of the capacitive wireless energy transmitting / receiving device in the same unit, together with external factors such as electromagnetic interference, lead to relatively low frequency in the channel. high amount of error and / or actual connection loss) to the capacitive channel (connector or antenna port) and thus to the system
