The kaon photoproduction is analyzed up to Eγ\rm Lab=2.0 GeV by using an isobaric model based on effective Lagrangians and by taking a cross symmetry into account. Both \it pseudovector and \it pseudoscalar couplings for kaon-baryon-baryon (baryon spin=1/2) interactions are considered with form factors. A vector meson(K^*(890)), an axial vector meson(K1(1270)), nucleon resonances(J≤5/2), and hyperon resonances(J≤3/2) are treated as participating particles. By determining unknown coupling constants through a systematic fitting of the differential cross section, the total cross section, the single polarization observable, and the radiative kaon capture branching ratio to their experimental data, we find out a simple model which reproduces all the experimental data well.
