Abstract
In this paper, we investigate the effect of microstrip patch element pattern on the linear array excitation required for equal sidelobes. Due to the pattern multiplication rule, the element pattern weights the array factor differently at different angles, therefore, excitation required for equal sidelobes will be different from the isotropic chebyshev case. Both broadside and scanning cases have been discussed and a method to obtain equal sidelobes for both cases has been given. Since, the microstrip patch element pattern, either in E-plane or H-plane, is dependent on its dimensions, the effect of changing the dimensions has also been discussed. It is shown that the broadside beamwidth(FNBW) of the new excitation is better than the Isotropic Dolph excitation.
