Remote-inquiry surface acoustic wave component with optimum code space

Narrated the code numerical, wherein the system with the same size structure resolution (DISTANCE) is, ratio technology method, the numerical code capable of using the same code unit to realize the code distance., Wherein the first code range is used, a code of the code scheme to a at code unit. The encoding unit reflector (21 or resonance 220) is a lead, wherein a new limit with a background type grills (30), a resolution structure (DISTANCE) is matching, the grille is thinner background count (130) scale (Delta). The improved program of - wave.
