Certain Study on Improvement of Bandwidth in 3 GHz Microstrip Patch Antenna Designs and Implemented on Monostatic Radar Approach for Breast Cancer Diagnosis in Microwave Imaging System

摘要

A 3 GHz class of an E-F and Psi(U) shaped Microstrip Patch Antennas (MPAs) designed, simulated and fabricated has been presented in this paper. These simulated designs with appropriate parameters are implemented on the fabrication prototypes which have been validated with help of Agilent Microwave Analyzer (N99917A). These proposed MPAs and dielectric equivalent human breast model that have been validated using the different dielectric strengths of coupling mediums are presented. These MPAs and dielectric equivalent human breast model have been validated using the existing Debye test bed. The coverage and vector dimension of tumor tissues have been detected using the Monostatic radar approach in the E-F and Psi(U) shaped MPAs-based existing Debye test bed setups. This paper conclude that Fractional Bandwidth (FBW) of E-F shaped MPA is 26.79% greater than Psi(U) shaped MPA of 21.67%. Hence, the E-F and Psi(U) shaped MPAs prototypes are suitable for breast cancer diagnosis systems. The prototypes' depth, coverage and vector dimensions are presented in this paper.
