An Ultra Wide Band (UWB) transmitter 210 and receiver 214 are inductively coupled via electrical coils (260, 262 in fig. 2c) in coupling elements 208a and b comprising "bishops hat" antennas, allowing operation within a short near-field range over a gap (eg. 1 cm) without physical contact connectors. Contactless connectors improve the reliability of eg. laptop docking stations or phone cradles and allow operation in underwater or hazardous "spark risk" environments, while retaining the low power and gigabits per second data rate of impulse UWB signals, with the short range also eliminating mulitpath interference. Different alignments or polarizations of the coupling elements (fig, 4d) may invoke different operational functions. An electrical backplane accommodates card sockets, mechanical interfacing is optional, and different protocols can be carried across the UWB link synchronously via protocol tunnelling, as discovered by a service discovery protocol. |
