function similar to Vivaldi element pattern

I am using matlab for mathematical analysis of antenna array. In this, for generating unidirectional beam AF is to be multipled with element pattern. I used the functions like cos(theta),sin(theta),1+cos(theta),1+sin(theta),1-cos(theta),1+sin(theta),a+bcos(theta),a+bsin(theta). my doubt is which function best suits for Vivaldi element pattern?

Dear Sireesha,

you may could use this documentation if you like to implement a vivaldi nothch antenna in Matlab.

Kind regards, Christiaan

To design Vivaldi antennas, use the Antenna Toolbox vivaldi, vivaldiOffsetCavity, and vivaldiAntipodal antenna objects which support the design, simulation, and analysis of radiation characteristics for standard, offset-cavity, and antipodal Vivaldi antennas in MATLAB.
