Miniaturization of rectangular patch antenna through a combination of fractal and defected ground structure / Umin Amirah Zakaria

This thesis presents a design of rectangular patch antenna incorporates with fractal and defected ground structure (DGS) for radar application. There are two antennas; conventional and fractal patch were fabricated on RO3003 substrate. The RO3003 substrate has relative permittivity, er = 3.0, and he...
