    "abstract": "A new type of high-impedance surfaces (HIS) has been introduced by C.R.\nSimovski et al. recently. In this paper, we propose to use such layers as\nartificial magnetic materials in the design of patch antennas. The new HIS is\nsimulated and patch antennas partially filled by these composite layers are\nmeasured in order to test how much the antenna dimensions can be reduced. In\norder to experimentally investigate the frequency behavior of the material,\ndifferent sizes of the patches are designed and tested with the same material\nlayer. Also the height of the patch is changed in order to find the best\npossible position for minimizing the antenna size. This composite layer of an\nartificial magnetic material has made the antenna smaller while keeping the\nbandwidth characteristics of the antenna about the same. About 40% of size\nreduction has been achieved.",
