A wireless slip ring, system and method for transmission of data across a rotatable junction can be provided to permit transmission of data from a fixed element to a rotating element across a rotary interface. The wireless slip ring can provide high bandwidth multi-channel data transmission, for example each channel can have a bandwidth greater than 1 gigabit per second. Each channel may include a plurality of input/output data streams that can be serialized by a digital electronic circuit for transmission across the slip ring and then deserialized into its respective data streams. The wireless slip ring can form an annular chamber to act as a wave guide for the wireless signal for providing a continuous conductive covering around the annular chamber to act as a faraday shield to contain radio frequency emissions and prevent external jamming.
