The hole-slotted coil design provides a deeper RF penetration into the sample compared to standard loop designs and has already been shown to operate as an array with capacitive decoupling at 7 T. In this work, the applicability of overlap decoupling in a hole-slotted loop-geometry array is investigated at 1.5 and 7 T. The overlap ratio for an optimal decoupling has been experimentally found. The hole-slotted geometry is a well-suited design in an array setup using overlap decoupling. At 7 T has been shown to have approximately the same RF penetration than the hole-slotted array with capacitive decoupling.
