Abstract

In this paper we describe the design and evaluation of Vivaldi elements optimization ‎for operation in the array environment over a wide range of frequency (12-18GHz). ‎The Finite Difference Time Domain (FD TD) is used in design and analysis of finite ‎Vivaldi array and genetic algorithm (GA) for optimization of its radiation pattern. The ‎hybrid method is used to find maximum side lobe level (SLL) over a range of ‎frequency (12-18GHz) by adjustment of the antenna and array parameters. An array ‎SLL improvement of MB was attained by optimization. Here a single VIVALDI ANTENNA ‎and a four-element array are analyzed and compared with measurements. Theoretical ‎and experimental results show good agreement with each other.‎
