A mono-surface 8Tx/16Rx antisymmetric dipole antenna array was designed and tested for parallel transmit (pTx) cardiac magnetic resonance imaging (cMRI) in pigs at 7T. The antisymmetric array comprised of a mono-surface 16-dipoles arranged so that two central L-shaped dipoles were anti-symmetrically flanked by 7-dipoles on either side. Combined FA, SNR, and g-factor maps were acquired in phantom using the dipole antenna array and compared with an 8Tx/16Rx loop array. After $$$B_1^+$$$-shimming using the dipole array, the SNR was enhanced by ~20% and FA by ~42%. Dipole antenna array has demonstrated ~20-times improvement in RSD of the FA after $$$B_1^+$$$-shimming.
