In ultra-high-field MRI, both curl-free (dipole-like) and divergence-free current patterns (loop-like) are desired for better parallel transmission performance as well as to approach the ultimate receive performance for deep tissues. But decoupling dipole antennas is still a challenging topic. However, as shown in previous work, the strongest coupling in a dipole array is actually end-to-end between elements. Another challenge when using dipoles in dense arrays comes from their length, 45 cm at 300 MHz. We propose a novel, folded figure-of-eight (Fo8) configuration to shorten the dipole and simultaneously make it self-decoupled from others.
