A comparative study performance on elliptical micro strip patch antenna (EMPA) using various feeding methods at an X band (8 GHz to 12 GHz) frequency range is presented in this work. The general X band frequency range varies from 8 GHz to 12 GHz, in this frequency range 9.8 GHz operating frequency is selected for RADAR communication application. The proposed work can also determine in detection of vehicle speed, military, civil and various wireless communication application systems. In this, the selected feeding techniques are micro strip fed planar, ring pin-fed, pin-fed circular polarized and edge-fed circular polarized. The elliptical patch antenna is designed, simulated and analysed with different feeding techniques at 9.8 GHz band, 4.5 dielectric constant of Rogers substrate material and thick ness of substrate the is 0.6 mm. The main aim of this EMPA with various feeding concepts presents comparative study performance on different parameters like, s-parameter (S11), vswr, bandwidth, directivity and gain using CST Micro Studio simulation software.
