Abstract

This paper strives to postulate a design expression for the first null beam width (FNBW) of Dolph Chebyshev linear antenna array which facilitates the angular resolution analysis of main beam. The formula for FNBW has been deduced by observing variation of FNBW with required side lobe ratio. Variation of FNBW with inter-element spacing for different array configurations has also been taken in to consideration. FNBW value obtained using the proposed formula has been compared with that of FNBW value obtained from the array factor plot proving its effectiveness.
