Satellites are very prominent for current and future communication applications like broadcasting, 5G and Military Communications. Most of the Satellites are used for radio communication. For communicating purpose, the satellite antenna must have unique characteristics such as circular polarization, broad beam width and good axial ratio. In order to have such type of unique characteristics, the micro strip patch antenna is the suitable antenna for Satellite applications because of its advantages. In this paper, a Wide band DGS circularly polarized micro strip patch antenna has been proposed for C-Band Satellite Communication Applications. Two defects or slots are introduced in the ground plane and those are orthogonally overlapped to get the circular polarization characteristics. In addition to this, these two slots enhance the bandwidth of the patch antenna by tuned to different frequencies. Moreover, the patch with defective ground structure is simulated and fabricated. Also measurements are carried out and obtained results are compared with the simulated results. It is noted that all the simulated and measured radiation patterns of the antenna have been carried out for all the frequencies and data has been compiled. However, some of the simulated and measured radiation patterns are included in this paper due to space constraint.
