In this work, we explored properties of various coaxial dipole designs and compared them with the conventional dipole. Dipoles were fabricated of RG58 coaxial cable and the total length was 34cm. S-parameters and flip angle maps of individual elements and array configurations were measured on a torso phantom. Comparison of flip angle maps shows very similar performances of all examined dipoles with the coaxial dipole being slightly advantageous. When placed in densely populated array configuration, coaxial dipoles were sufficiently decoupled and produced expected B1+ maps. Coaxial dipole shows promising performances to be used in a densely populated flexible torso array.
