In the design of coils, it is required a uniform current distribution in the loop to generate a homogeneous magnetic field. In the broad-side coupled split ring resonator (BC-SRR) design, the sum of the currents flowing in the two rings is constant so that the field produced is homogeneous. A BC-SRR and two conventional loops were simulated and built at 7T. In the design of loops with distributed capacitance, it is not necessary to split the ring in several gaps. The total current flowing in the two loops of the BC-SRR design is constant independently of the number of gaps
