We present an extended study of our previous work on an alternative five-dimensional N=2 supergravity theory that has a single antisymmetric tensor and a dilaton as a part of supergravity multiplet. The new fields are natural Neveu-Schwarz massless fields in superstring theory. Our total matter multiplets include n copies of vector multiplets forming the sigma-model coset space SO(n,1) / SO(n), and n' copies of hypermultiplets forming the quaternionic K\"ahler manifold Sp(n',1) / Sp(n') X Sp(1). We complete the couplings of matter multiplets to supergravity with the gauged group of the type SO(2) X Sp(n') X Sp(1) X H X [ U(1) ]^{n-p+1} for an arbitrary gauge group H with p = dim H + 1, and the isotropy group Sp(n') X Sp(1) of the coset Sp(n',1) / Sp(n') X Sp(1) formed by the hypermultiplets. We also describe the generalization to singular 5D space-time as in the conventional formulation
