Abstract
This paper discusses rectangular patch microstrip antenna design by using left-handed metamaterial (LHM). Designed is on FR4 substrate with dielectric constant of 4.4 and 1.6 mm thickness. LHM structure is intended for bandwidth enhancement. By using the AWR simulator, LHM structure has been designed on 60x50 mm2 ground plane for rectangular patch microstrip antenna working on 2.4 GHz. Based on simulation results, the use of LHM structure is able to extend bandwidth up to 175.7 MHz with bandwidth enhancement reaching 213.75% larger than without LHM. The minimum return loss is about -21.93 dB on 2.4 GHz. The miniaturization ration of the patch dimension achieves 14.6%.
