En el ámbito de la aplicación práctica de la invención es sabido que los sistemas detectores de señales de radar actuales, entre las frecuencias (33,392 y 35,998) Y (24 ,000 Y 24,350) GHz, no siempre tienen una ganancia adecuada que permita su detección de forma fiable y a una distancia suficiente con respecto al foco emisor. Within the scope of the practical application of the invention it is known that current radar signal detecting systems, between frequencies (33,392 and 35,998) and (24, 000 and 24,350) GHz, do not always have an adequate gain that allows their detection reliably and at a sufficient distance from the emitting bulb.
