Abstract : A notch antenna for the elimination external interference sources such as jamming, self-interference atmospheric noise and man made noise is provided by a grounded electrically conductive shield placed in the front of an omnidirectional antenna coupled to radio communications apparatus, such as a receiver, whereby the shield blocks electromagnetic waves arriving within an angular arc defined by the position and size of the shielding element.
