We report theoretical investigations of indirectly coupled double quantum dots (QD) side connected to an one-dimensional quantum wire. Due to quantum interference controlled by the parameter kFL, with kF the Fermi wave number of the wire and L the distance between the two QDs, distinctly different Kondo resonances are predicted depending on the range of kFL. A true bound Kondo states is found while an anomalous Kondo resonance gives rise to both reduction and enhancement of conductance.
