Terahertz imaging patch antenna for cancer diagnosis applications

Abstract

Cancer is the world second most common syndrome which causes death. In statistics nearly one of every four death occurs day-to-day, but it is remediable if detected earlier. The numerous imaging technologies exist for diagnosis with different constrains but those techniques provide either macroscopic or microscopic imaging. Microscopic imaging methods are used in histopathology of biopsy samples to provide corporeal and functional information and in macroscopic level X-ray and MRI are used to provide images of living tissues and can achieve only much poorer resolution and specificity. Moreover it is harmful in terms of radiation and other causes. One of the prime mysterious complication in medical imaging is how to syndicate the macroscopic and microscopic imaging progresses so that the precise margins of cancers can be delineated. The THz-tomography research does that syndication and achieves much high resolution with Non-ionizing radiation. The proposed nano-material based Microstrip antenna is pertinent to do THz-tomography with low cost and high resolution which can diagnosis and detection various cancers such as skin cancer, breast cancer, cervical cancer and colon cancer. In this paper, a terahertz imaging antenna was designed and analyzed using Ansys - HFSS v. 14 simulation tool.
