Abstract: A micro strip antenna comprising a planar substrate fabricated from a dielectric material and a pair of like elements arranged in mirror image on the planar substrate, each of the elements comprising a radiating portion comprising an elongate conductive strip of a constant thickness, the elongate conductive strip comprising first arcuate side edges mutually diverging between a narrow end and a wide end. There is also disclosed a system for detecting the presence of a region having a first dielectric constant within a medium having a second dielectric constant different from the first dielectric constant, such as a tumour embedded in a fatty tissue.

Abstract: A non-invasive method to detect vascularization associated with one or more malignant tumors in living tissue of a living organism, where dielectric properties of the vascularization are different than dielectric properties of normal living tissue. In one embodiment, a non-ionizing input wave within a wide band frequency range is generated, and the input wave is applied to a field excitation antenna to illuminate a discrete volume within the living tissue of the living organism and to develop scattered power returns from the discrete volume. A receiving antenna then collects at least a portion of the scattered power returns. The scattered power returns are detected and then applied to a signal processor to develop a segregated signal, which is then processed in order to identify the vascularization associated with one or more malignant tumors.
