Exploiting the the Kaluza-Klein decompositions, we study the hierarchy between the Planck and electroweak scales on extended brane models with dimensionalities greater than that of the standard Randall-Sundrum model. Specifically, the extended dimensional four-brane and five-brane are constructed by attaching a circle and a sphere to the three-brane, respectively. Constructing the Kaluza-Klein modes on the extended five-brane, we obtain its effective masses which are shown to suppress exponentially with respective to the Planck mass, similar to the standard three-brane case. However, the effective mass spectrum on the four-brane implies intriguing characteristics associated with the quantization of the compact circular manifold.
