Abstract. Short range inductive data transfer has become very popular in the last years
with the increased interest in technologies like RFID and NFC. Additionally,
wireless power transfer has been a field of intensive research and product
development. In industrial applications, a combination of both is often
needed to replace mechanical contacts, mainly for safety and reliability
reasons, especially regarding spark prevention and maintenance reduction. In this paper, we present a compact inductive structure that can be
implemented in an existing wireless energy transfer system. The structure is
developed by field considerations, leading to a single structure comprising
two signal ports that are decoupled from each other, but can be used to
transfer a signal to a second structure of that kind with very small
interference. An optimisation to achieve comparable channel characteristics
is conducted by using 3-D field simulations. Subsequent measurements are
conducted to verify the achieved performance.
