Antenna miniaturization and multiband are accomplished by employing a fractal loop on the DGS structure and a split ring resonator slot in the patch. The proposed radiator has a hexagonal shape that operates at 6.8 GHz. To achieve downsize of 20.58, 38.22, 55.14 and 72.75% an antenna is designed using DGS and DMS structures for quad-band application appearing at 1.85, 3.05, 4.2, and 5.4 GHz. Simulated and tested data are investigated. The prototype antenna has adequate advantages, with a simple structure, compact size, multiband, and uniform radiation patterns.enDMSDefected Ground StructureFractal structureMiniaturized planar antennaQuad-bandSRRArticle
