In this work, we demonstrate a new double bent dipole geometry for use as a hybrid RF/B0 shimming element for 10.5T imaging, featuring two B0 shimming channels per RF channel. Initial simulations compare this element to standard dipoles and loops. Bench assessments and simulations further demonstrate excellent inter-element decoupling, and initial steps toward a 32-channel Tx/64-channel B0 array show promising results.
