Previous work demonstrated that it is feasible to design non-array volume coils using the coupled dipole antennas. However, the weak coupling of the standard dipoles and over-length make the design difficult and also limit its utility. In this work, we propose a modified dipole structure which can be used for high frequency non-array volume coils with improved coupling. It also provides certain flexibility in coil length control. Results of the proposed design at 400 MHz and 500MHz (i.e. 9.4T and 11.7T) are presented.
