A large-size loop coil suffers from the current phase inversion along the loop surface and therefore weak the current intensity at the phase inversion points. A new RF coil using coupled line phase shifters is presented for body imaging at 7T MRI. This design can retain an in-phase current along the loop when the perimeter is larger than 1.5$$$\lambda$$$ ($$$\lambda$$$ is the wavelength in free space). An 8-channel coil array using this new design is simulated and compared with a conventional loop array. The results indicate that improved $$$B^{+}_{1}$$$ shimming can be achieved in a large region of interest.
