Claim Text:
1. An antenna circuit that is adapted to supply, read out, or supply and read out a plurality of antenna elements of an antenna assembly of a magnetic resonance imaging system, the antenna circuit comprising: a first circuit connector that is adapted to be connected to a receiving, transmitting, or receiving and transmitting circuit; a first antenna-side connector that is adapted to be connected to a first antenna element of the antenna assembly that forms a parallel resonance circuit, and a second antenna-side connector that is adapted to be connected to a second antenna element of the antenna assembly that forms a series resonance circuit; and a first phase shifter element and a second phase shifter element that each cause a phase shift of a signal of 90° or 270° and each have a predetermined admittance, wherein a first connector of the first phase shifter element and a first connector of the second phase shifter element are connected to the first circuit connector, and wherein a second connector of the first phase shifter element is connected to the first antenna-side connector and a second connector of the second phase shifter element is connected to the second antenna-side connector, wherein a ratio of currents in the first antenna element and the second antenna element is provided by the predetermined admittances of the first phase shifter element and the second phase shifter element.
