Far field value in cartesian coord is unequal to transformation from polar coord

      Hi. 

      In HFSS,

      I obtained the realized gain values of polar coordinate which correspond to theta & phi component from dipole antenna simulation. 

      And also, the realized gain values of cartesian coordiante which correspond to x component (for simplicity, I exclude y, z)

       

      After that, I transformed theta & phi value to x value by using transformation relation between spherical and cartesian coordinate.

      But, the x value that I calculated is different from the x value of HFSS.

      So, I ask for the transfomation relationship between spherical and cartesian coord used in HFSS.

      I attached the transfomation equation that I used and the theta, phi and x values of HFSS.
