Abstract

Dispositivo de antena de cuadro electrostáticamente apantallada, para un receptor de señales de radio, el cual comprende un núcleo de material magnético de alta frecuencia, un arrollamiento inductivo de cuadro que rodea dicho núcleo, una pantalla que rodea el arrollamiento de cuadro espaciada con respecto a éste, y medios terminales para conectar la pantalla y el arrollamiento con dicho receptor; caracterizado por el hecho de que dicha pantalla comprende un material resistivo que tiene una impedancia resistiva relativamente baja al paso de corrientes de perturbación a su través hasta la masa de tierra, por acoplamiento electrostático, y relativamente alta al paso de corrientes parásitas de señal inducidas en ella desde dicho arrollamiento.
