ABSTRACT
A distributive reflective array is typically composed of a series of shorted metal electrodes, etched grooves in the substrate, or dielectric strips. There is a physical discontinuity on the substrate surface due to the individual reflectors. Each reflector is one-quarter wavelength wide and the periodicity of the array is one-half wavelength. This is shown schematically in Figure 6.14. The net reflections from all the individual array elements add synchronously at center
frequency, resulting in a very efficient reflector. The reflection from each array element is small and very little spurious mode coupling results.
