Summary: We introduce a class of noncommutative and noncocommutative weak Hopf algebras with infinite Ext quivers and study their structure. We decompose them into a direct sum of two algebras. The coalgebra structures of these weak Hopf algebras are described by their Ext quiver. The weak Hopf extension of Hopf algebra \(H_n\) has a quotient Hopf algebra and a sub-Hopf algebra which are isomorphic to \(H_n\).
