A single channel 1H saddle coil and a quadrature 1H 8-leg birdcage coil were compared in terms of $$$B_1^+$$$ homogeneity and $$$B_1^+$$$ efficiency for preclinical small-animal imaging at 14.1 Tesla. Electromagnetic field simulations showed that the saddle coil generated a more homogeneous $$$B_1^+$$$ field for all regions of interest (up to 13.7 mm central disk diameter) than the birdcage coil. Saline phantom measurements showed a more constant flip angle excitation upon multi-slice imaging in axial direction and a 66% higher $$$B_1^+$$$ efficiency for the saddle coil.
