Performance Evaluation of Printed Microstrip Antennas with PSR & DGS

High performance, low cost and compact size modules are required for the modern communication systems. To design such models, we should depend on the modern technology-based materials and new techniques such as Defected Ground Structure (DGS), Electromagnetic Band Gap (EBG), Partial substrate Removal (PSR), and Photonic Band Gap (PBG). The Design of antennas with defected ground structures will explore additional resonant frequencies and the improvement in bandwidth is also possible. In this work, design and analysis of CPW-fed monopole antenna for UWB applications are proposed with defected ground structure. Later, a compact L-shaped monopole is designed and substrate removal technique is applied to enhance the bandwidth of the antenna. A fractal antenna with a swastika-shaped structure is designed and a substrate removal technique is applied to enhance the gain of the antenna. Finally, a circular half ring monopole antenna, Stub loaded circular-shaped antenna and a circular notch band antenna a circular notch band antenna a circular notch band antenna a circular notch band antenna a circular notch band antenna with DGS are proposed for ultra wide band applications.
