Abstract :
The paper considers the copolar and crosspolar radiation patterns of a finite array of conical horn elements in which full account is taken of the effects of mutual coupling. Mutual coupling between, respectively, the TE11- and TE21-, and the TE11- and TM01-modes has a marked effect on copolar pattern symmetry and on the level of crosspolarisation. Contour plots are given for `clean-beam¿¿ excitation of the arrays, and the influence of horn aperture size is shown to be significant.
