Microstrip patch antenna with defected ground structure (DGS) using metamaterial / Mohd Hellme Vellame

Metamaterial exhibiting negative permittivity and negative permeability in certain frequency range or known as left-handed material (LHM). It provides another alternative to the existing right-hand rule. This theory offers a new dimension to the antenna applications. This project looks into the effe...
