Abstract

A local coil includes a coil element in the form of a loop. The coil element includes a first conductor, a second conductor, and a third conductor. The coil element includes a first dielectric and a second dielectric. The first dielectric is arranged between the first conductor and the second conductor, and the second dielectric is arranged between the second conductor and the third conductor. The coil element includes a receive unit that includes the first conductor and the second conductor, and a detuning unit that includes the third conductor. In a first operating state of the coil element, the receive unit has a first resonant frequency. In a second operating state of the coil element, the detuning unit is configured to detune the resonant frequency of the receive unit so that the receive unit has a second resonant frequency different than the first resonant frequency.
