A magnetic resonance antenna has capacitive and inductive oscillating circuit antenna elements at least one radio-frequency switching element with which at least one of the oscillating circuit antenna elements that determine the resonant frequency of the magnetic resonance antenna, can be switched at radio frequency between a permeable state and an impermeable state to change the resonant frequency of the magnetic resonance antenna, so the antenna can be detuned simply, cost-effectively and efficiently. |
