摘要

1. Broadband notch filter as a device for protecting a vehicle driver against geopathogenic zones and from the vehicle electrical radiations comprising electromagnetic circuits interconnected, characterized in that it consists of a flat two-way glass-cloth substrate clad with copper on which the center has eight concentric circles obtained by etching with the track width at least 2 mm and diminishing toward the center with constant shagom.2. Filter according to claim 1, characterized in that, to improve the efficiency, is provided with plated copper doped silver and gold.
