  The chiral SU(3) quark model is extended to include an antiquark in order to
study the kaon-nucleon system. The model input parameters $b_u$, $m_u$, $m_s$
are taken to be the same as in our previous work which focused on the
nucleon-nucleon and nucleon-hyperon interactions. The mass of the scalar meson
$\sigma$ is chosen to be 675 MeV and the mixing of $\sigma_0$ and $\sigma_8$ is
considered. Using this model the kaon-nucleon $S$ and $P$ partial waves phase
shifts of isospin I=0 and I=1 have been studied by solving a resonating group
method (RGM) equation. The numerical results of $S_{01}$, $S_{11}$, $P_{01}$,
$P_{03}$, and $P_{11}$ partial waves are in good agreement with the
experimental data while the phase shifts of $P_{13}$ partial wave are a little
bit too repulsive when the laboratory momentum of the kaon meson is greater
than 500 MeV in this present calculation.
