    chaching the Gain of each polarization

    Hello , the Sinuous antenna that i have built is dual polarized because it hase two orthogonal dipole feed,i have attached the diagram and farfield results of the simulation.
    this antena is dually polarized, i have used ludwig 3 on vertical /horizontal as shown in the attached photos.
    how can i interpret the ludwig 3 diagram and get the directivity of each polarization.

    thanks

    The directivity diagram dosen't look right. As it is symmetrical you should have the same radion pattern in H and V.
    It looks like it's basically is just a wrinkled up cross dipole, if so it should have the same radiation pattern as a dipole.
