Abstract

Design of antennas for satellite communication applications like Global Positioning Systems, Geo Informatics Systems became crucial for real time data collection and transmission. A novel Defected Ground structure planar monopole antenna for broadcasting satellite communication applications is proposed in this study. The proposed model has a unique structure with the combination of rectangular, arrow lined and T-slotted inverted U-shaped structure as a radiating element on the topside of the substrate. The ground plane on the bottom side of the substrate consisting of a rectangular slotted defected ground structure. The designed antenna has a small overall size of 32X26X0.8 mm with polyster as a substrate material. The results show that the antenna gives monopole like radiation pattern and a good antenna gain over the operating bands. The proposed antenna performance characteristics are well suited for fixed and broad casting satellite communication applications.
