Abstract

An antenna arrangement for acquisition of a magnetic resonance signal has at least two acquisition antennas, each having at least one conductor loop and each conductor loop having an interruption therein. The conductor loops are connected in parallel at the interruptions and a capacitive decoupling element is arranged in at least one of the interruptions. The acquisition antennas are connected with one another via at least two capacitive blocking elements, and all capacitive blocking elements and all capacitive decoupling elements together exhibit a capacitance at which the acquisition antennas are decoupled from one another. The acquisition antennas are connected with one another via an inductive element that is connected in parallel with the capacitive blocking elements. The inductive element exhibits an inductance at which a common mode signal between the acquisition antennas is suppressed.
