  We replace the scalar Higgs doublet with a vector Higgs boson doublet to the
unified electroweak W-S model and find most of important features of W-S model
are kept unchanged only the Higgs boson now become vector bosons. Lorentz
invariance has been carefully discussed. The most important challenge is there
will be three massless vector Higgs bosons. The remarkable effect is the
possible suppression of the flavorchanging neutral current compare to the
multi-Higgs model.
