Induktiver Sensor (10), aufweisend ein kreisförmiges Substrat (20), auf dem nebeneinander 2 bis 3 Sende-/Empfangsspulen (31, 32, 33) angeordnet sind, wobei jede Sende-/Empfangsspule (31, 32, 33) als offene Spule ausgeführt ist und jeweils eine Windung aufweist. An inductive sensor (10) has a substrate (20), on which multiple transmitter/receiver coils (31, 32, 33) are arranged side by side. It can be operated in such a way that the transmitter/receiver coils (31, 32, 33) are each stimulated independently of one another at a frequency of more than 100 MHz.
