Abstract:
The main objective of this project is to analysis and design of ultra ultra wideband dual polarization vivaldi antenna array for electronic support measure system. In modern satellite communication and radar systems, antenna are required to have the characteristics of both ultra wide band and dual-polarization so as to satisfy various needs such as expanding the information volume, improving the quality of receiving information and increasing the ratio of bandwidth utilization. For this reason we first design a single element of vivaldi antenna for 6-18GHz range and then with design of SMA connector shown that result with and without SMA is same. In the next step we design(under consideration mutual coupling) linear array in E_Plane and H_Plane configuration and then design planar array with 16 element. Then, with the introduction of the solution, we design dual polarization antenna array and All simulations were performed with CST and HFSS software. Finally we design three stage, four port wilkinson power divider and All simulations were performed with CST and ADS software
