An Active Microwave Sensor for Near Field Imaging

Abstract

Abstract-Near field imaging using microwaves in medical applications is of great current interest for its capability and accuracy in identifying features of interest, in comparison with other known screening tools. This paper documents microwave imaging experiments on breast cancer detection, using active antenna tuning to obtain matching over a wide bandwidth. A simple phantom consisting of a plastic container with a low dielectric material emulating fatty tissue and a high dielectric constant object emulating a tumor is scanned between 4 to 8 GHz with a UWB microstrip antenna. Measurements indicate that this prototype microwave sensor is a good candidate for such imaging applications.

A Metamaterial-Based Compact Planar Monopole Antenna for Wi-Fi and UWB Applications

“…The UWB frequency range is defined as 3.1-10.6 GHz by the Federal Communications Commission (FCC) [3,4]. UWB antennas play a role in many applications, such as surveillance systems, medical applications, wireless sensor networks, and the Internet of Things (IoT) [5][6][7][8]. However, there are limitations on UWB antennas.…”

A T Slot Monopole Antenna for UWB Microwave Imaging Applications

“…Microwave imaging applications in non-destructive experiments have had a tremendous and vital impact in both civilian and military applications. Microwave imaging applications in non-destructive experiments also finds ongoing and potential applications for several medical applications such as breast cancer imaging application [1][2][3]. Breast cancer remains a major cause of death among women in the United Kingdom with one in eight women being diagnosed; thus, causing many thousands of deaths every year [4].…”
