Transmit (Tx) array with multiple independent coil elements is a well-recognized approach to addressing the B1 inhomogeneity and high local SAR issues at ultrahigh fields. However, Tx arrays typically have a lighter loading and more severe coil coupling. We designed a self-shielded and self-decoupled 2x8 Tx array with high inter-element isolation for 7T head imaging. Each Tx element is based on the corner-fed self-decoupled coil. Four coil elements were constructed to prove the concept is viable. The coil elements are highly decoupled (inter element response < -15 dB) while maintaining good tuning/matching characteristics (power reflection < -20 dB).
