We demonstrated a highly efficient B₁⁺to-SAR dipole antenna for ultrahigh-field MRI which consists of a double-folded ladder structure. The antenna was simulated and bench tested. The antenna has a high impedance which provides low mutual coupling between other antenna elements. Ultimately, this characteristic possibly allows to construct antenna array for pTx.
