A new artificial spin ice lattice called vortex lattice is proposed based on the Kagomelattice. Monte Carlo simulations were performed to investigate the magnetization reversalprocess of the new artificial spin ice lattice at external magnetic field and differentlattice parameters. The results demonstrate some interesting phenomena which are differentfrom Kagome lattice. There are four typical sub-structures emerged in the vortex lattice,which are clockwise and counter-clockwise hexagons, and frustrated +3q and -3q vertices.The occurrence frequency of the four sub-structures change dramatically at differentlattice parameter. The new lattice can be partially frustrated at different latticeparameter
