In this paper, the authors presented periodic structure implementation in antenna design for wireless application and these antennas were compared with CRLH miniaturization method. Here, have been presented three different model of patch antenna with coaxial feed on EBG ground, metamaterial substrate or EBG/AMC structure. Also presented two model antennas with CRLH techniques for dual band antenna. Here presented the comparison between gain, bandwidth and miniaturization factor of these patch antennas. All presented model antennas are modified for wireless application at 2.4GHz. Simulation has been done in HFSS for the full wave method.
