Abstract
AbstractThis paper proposes a simple low-profile high-gain wideband antenna for Ku-band satellite applications that utilize a block of left-handed metamaterial for gain enhancement over conventional patch antenna. This antenna is designed and simulated using Ansys HFSS. It was found that performances of the simple patch antenna are improved by inserting left-handed material superstrate. The proposed antenna performs in Ku-band which is applicable to satellite applications. The proposed antenna resonates in 11.97 GHz. The left-handed material is realized by incorporating a layer of array of metallic rings with the conventional rectangular patch antenna.KeywordsConventional antennaMetamaterialCircular ringsGainLeft-handed materialGainPermeabilityPermittivitySatellite
