ABSTRACT:
A radio-frequency antenna has two end rings and a number of antenna rods that form a birdcage resonator. A coupling element couples high-frequency electromagnetic energy into the resonator in the transmission mode and out therefrom in the reception mode. The coupling element is fashioned as a conductor system tangentially surrounding the resonator and into which a high-frequency systems of currents can be fed in the transmission mode or from which a high-frequency system of currents can be fed out in the reception case. The coupling element is coupled only inductively to the resonator.
