Sensors are labelled as prominent tools to analyze biological and physiological parameters of breast cancer patients for prognosis and diagnostic purposes. Currently, wide band radio frequency sensor based technology is gaining momentum for primitive stage breast cancer detection. In this research work, a RDRA is proposed as key sensor part which leads to design of smart data acquisition system. Rectangular DRA resonates for a frequency range of 2.9-4.7 GHz (48% Impedance bandwidth) which lies in the Lower European frequency band. Peak gain of 4dB is obtained through proposed antenna. High radiation efficiency, compact size of the antenna makes it perfectly suitable to be employed as a sensor for early breast cancer detection. Proposed antenna can be integrated with wide band wireless communication for Wi-Fi and LTE communication and Wireless Body Area Networks (WBAN) applications as well.

Radio sensors possess several characteristics in comparison of the contemporary counterparts. Due to which they are ardent candidate for detection of early stage of breast cancer. In this paper, the antenna structure highlights the hybridisation of Ring Rectangular Dielectric Resonator [RRDR] placed on multiple ring patch, which operates at a frequency band of 5.4–15 GHz. Impedance bandwidth of 94.1% is achieved with the hybridisation of patch and dielectric resonator antenna along with slotted ground structure.

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.

An ultrawideband (UWB) antenna covering the lower terahertz band is designed and numerically analyzed. A number of higher-order modes are excited and merged to provide the UWB response. The band-notch is obtained by applying graphene nanoribbons at the top of the radiating metallic patch. The antenna response can be set with the tunable single/dual/triple band-notch characteristics depending on the size and location of the applied graphene nanoribbons. The notched frequency band can be tuned by changing the chemical potential of the graphene nanoribbons by keeping the cutoff frequencies of the antenna response unchanged. Moreover, the antenna radiates like a monopole throughout the passband with consistent radiation pattern, high gain, and radiation efficiency.
