This paper presents a I-Shaped Metamaterial Patch Antenna with Defect Ground Structure (DGS), 4.5GHz operating frequency. This frequency is the application for broadband antenna. The construction of I-shaped DGS at ground plane contributes the metamaterial features to the antenna. Conventional antenna and metamaterial antenna has been simulated, fabricated and measured. The simulation design has been done using Computer Simulation Technology (CST) microwave studio and both antenna were fabricated on RO3003 substrate with dielectric constant 3 and 0.75mm height. The proposed of the project is to reducing the antenna size, and the same time, performance of the antenna in term of return loss and directivity not be neglected.
