Abstract:
A very wide band transmission/reception antenna for a non-ionizing, non-thermal system for detecting the presence of a tumor or an abnormality in the tissue of a living organism, said antenna comprising:a first radiation element of generally triangular planar configuration having an apex constituting one corner thereof,a first receiver element of generally triangular planar configuration having an apex constituting one corner thereof,said corners of said first radiation element and said corner of said first receiver element being located closely adjacent each other,a wide band width transmitter connected to said corner of said first radiation element,a wide band width receiver connected to said corner of said first receiver element,said first radiation element and said first receiver element each formed of an electrically conductive surface on a planar surface of a dielectric member,said dielectric member having a relative dielectric characteristic approximately the same as the dielectric characteristic of the living organism tissue,each electrically conductive surface decreasing in conductivity in a direction away from its said apex.
