An antenna arrangement (1) comprises an AC voltage source (3), a first inductive antenna element (L1), a second inductive antenna element (L2) and capacitive element (C). The voltage source (3) is electrically connected in parallel to a series connection of a first circuit section comprising the first inductive antenna element (L1) and a further circuit section. The further circuit section comprises a parallel connection of a first subsection comprising the capacitive element (C) and a further subsection comprising the second inductive antenna element (L2). The first and second inductive antenna elements (L1, L2) are wound on a cross-like magnetically conducting element (2). The antenna arrangement generates two positioning signals with a predetermined phase shift which allows accurate determination of the relative position/orientation between the antenna arrangement (1) generating the positioning signals and a receiving arrangement which receives the positioning signals.
