Abstract :
A five-element spatial power divider/combiner has been realized. Uniform illumination is performed by a dual offset reflector setup. Holography is applied to couple the pseudo-plane wave to an in-line rectangular horn antenna array. The theoretical power dividing/combining efficiency amounts to 85%. Corresponding measurements around 150 GHz show a maximum efficiency of 77% and a 70% -bandwidth of 4%.
