  In this letter, we theoretically and experimentally prove the possibility of
the complete passive decoupling for two parallel resonant dipoles by a
split-loop resonator. Unlike previously achieved decoupling by a similar
resonant dipole, this decoupling technique allows us to avoid the shrink of the
operation band. Compare to previous work, simulation and measurement show 100\%
enhancemnet of relative operation band from 0.2% to 0.4%
