The antenna is quite simple to fabricate and has perfect radiation characteristics. However in upcoming technology, smaller patch antenna needed to match well with future gadgets. The weakness of conventional MPA is that the size is comparable to half of its wavelength. In order to solve this weakness, a new method of using defected ground structure (DGS) having metamaterial characteristic can reduce the antenna size. The metamaterial response is verified in simulation based on scattering parameter using Nicolson-Ross-Weir (NRW) method. This thesis presents design, simulate and fabrication of miniaturized antenna operating at 5 GHz frequency. The DGS structures have been designed and fabricated. The design is I-shaped defect ground structure. The circuits are able to reduce the size from 12.05%. These antenna were simulated using Computer Simulation Technology Microwave Studio (CST MWS) and measured using Vector Network Analyzer (VNA). Both the simulated and measured data were compared. From the simulation, the DGS antennas design at 5 GHz has return loss value of negative 22.292 dB. The DGS antenna also increases the return loss value up to 46.67% compared to conventional one. 2013 Thesis https://ir.uitm.edu.my/id/eprint/81033/ https://ir.uitm.edu.my/id/eprint/81033/1/81033.pdf text en public degree Universiti Teknologi MARA (UiTM) Faculty of Electrical Engineering Hamzah, Norhayati
