We derive electroweak constraints on the compactification scale of minimal 5-dimensional extensions of the Standard Model, in which all or only some of the SU(2)L and U(1)Y gauge fields and Higgs bosons feel the presence of the fifth dimension. In our analysis, we assume that the fermions are always localized on a 3-brane. In this context, we also present the consistent quantization procedure of the higher-dimensional models in the generalized Rξ gauge. We find that the usually derived lower bound of ∼ 4 TeV on the compactification scale may be significantly lowered to ∼ 3 TeV if the SU(2)L gauge boson is the only particle that propagates in all 5 dimensions.
