Compared with regular single-row transceiver coil
arrays, multiple-row arrays exhibit larger imaging
coverage and the capability of parallel imaging and
parallel excitation along z-direction. The main
challenge in designing multiple-row microstrip array is
to attain sufficiently decoupling among coil elements
from adjacent rows. In this study, a novel decoupling
technique was proposed to address this problem. Both the
bench test and MR imaging results demonstrate that the
proposed technique could reduce the strong coupling
(-7.9 dB) between microstrip elements from adjacent rows
to a sufficiently small value (-25.3 dB).
