Abstract
An RF resonator has a birdcage resonator with two electrically conducting ring elements () and N electrically conducting bars (). At least one pair of electrically conducting ring segments () forms an additional electrical connection between precisely two bars (). The pair of ring segments () define a current path () with these two bars () which is capacitively interrupted at at least one point. The ring segments () and the bars () electrically connected to the ring segments () are disposed symmetrically with respect to the yz-plane. The field homogeneity and efficiency are thereby optimized even with frequencies that are far apart.
