N2 - Due to the wavelengths' reduction in the human tissues at ultra-high field MRI, head coils usually present B_{\mathbf{1}}^{\mathbf{+}} magnetic field inhomogeneities located at the brain's temporal lobes. Different approaches have effectively targeted this problem, at the cost of either decrease the B_{\mathbf{1}}^{\mathbf{+}} field in other regions or be uncomfortable to the patient. Here, we present a new approach based on Hilbert fractal inspired dipoles. Our structures improved simultaneously the B}_{\mathbf{1}}^{\mathbf{+}} field in each temporal lobe without diminishing the B_{\mathbf{1}}^{\mathbf{+}} field in other parts of the brain or the patients' comfort.
