Abstract
Sensor design using ultra-wideband (UWB) technology is considered powerful emerging technique to extract information about the state of biological and physiological conditions of human organs for diagnostic purposes. Recently, UWB radio sensor technology is being proposed for early stage breast cancer detection in view of some superior characteristics or bio-markers over current methods. In this paper, a RDRA is designed, leading to develop the smart data acquisition system. A novel RDRA structure is simulated, which operates in the range of 3.7-7.4 GHz (67% bandwidth) which lies in the lower European UWB frequency band. The positive gain of the proposed antenna is stable across the active bandwidth and the peak value is 2.5 dB, which makes the RDRA structure highly suitable for body centric applications, especially for early detection of breast cancer. Thus, the proposed RDRA antenna structure can be integrated for early stage breast cancer detection application as well.
