We present a realistic non-supersymmetric inflation model based on a gaugedU(1)$_{B-L}$ symmetry and a tree-level Higgs potential. The inflaton isidentified with the scalar field which spontaneously breaks U(1)$_{B-L}$, andwe include radiative corrections \`a la Coleman-Weinberg in the inflatonpotential. If the scalar spectral index $n_s$ lies close to 0.96, as indicatedby the recent Planck and WMAP 9-yr measurements, the tensor-to-scalar ratio$r$, a canonical measure for gravity waves, exceeds 0.01. Thus, according tothis model, gravity waves should be found in the near future. In this case, thequantity $|dn_s/d \ln k|$ lies in the range $0.004-0.005$. Successfulbaryogenesis can be realized in this class of models either via thermal ornon-thermal leptogenesis.
