1. An antenna arrangement comprising:
- an inductive transmitting antenna comprising a main radiating axis;
an inductive receiving antenna comprising a main receiving axis located in the main radiating axis of the inductive transmitting antenna; and
an inductive compensator which is electrically connected in series to the inductive receiving antenna and located in a first plane which intersects a second plane, the main receiving axis of the inductive receiving antenna being normal to the second plane;
whereinthe inductive compensator extends, at least in an area of a conductor of the inductive transmitting antenna, along the conductor.

Abstract
An antenna arrangement has an inductive transmitting antenna having a main radiating axis, an inductive receiving antenna having a main receiving axis, and an inductive compensator. The inductive receiving antenna is arranged in the main radiating axis of the transmitting antenna. The inductive compensator is electrically connected in series to the receiving antenna and is arranged in a first plane which intersects a second plane. The main receiving axis of the receiving antenna here is normal to the second plane.
