A printed drooping dipole array is designed and constructed. The design is based on a genetic algorithm optimisation procedure used in conjunction with the software programme AWAS. By optimising the array G/T for specific combinations of scan angles and frequencies an optimum design is obtained which has fairly low scan loss for wide angles within a frequency range 300 MHz around 1.6 GHz. From measurements of the active element patterns of the prototype the array G/T is calculated and the results are in fairly good agreement with the simulation results.
