Abstract :
The analysis and realisation of printed antenna arrays with low sidelobes using a tapered excitation are described. The array is divided into several independent subarrays, fed at their centres by a low-loss corporate feed network. To achieve the correct radiation pattern, each subarray must exhibit a dissymmetrical source excitation; equations are derived to calculate the transformation ratios along the linear series subarrays. Theoretical and experimental results are in good agreement.
