One of the applications of UWB antenna is for detecting a cancer tumor according to breast cancer model system. The absolute dimensions of antenna are 44x30mm2 having a thickness of 1.6 mm. It involves Ultra wide band of 80% frequency range of 3 GHz–12 GHz for the FCC band. The proposed antenna resulted high gain and omni-directional radiation patterns and a considerable impedance matching. The optimized functioning of the antenna is illustrated by the simulation results. This antenna has been implemented in a designed system model with dielectric properties of a human breast capable to detect peculiar bodies. The tumor is detected and examined by the received Proportions and Positional coordinates, accessed by the application of UWB antenna. The accurate position coordinates of the tumor inside the breast are obtained at the places with the least Specific absorption rate (SAR). The antenna was used to localize the tumor precisely which shows the excellent functioning of the antenna and device. The proposed device is simulated by using Ansoft HFSS software and also CST Microwave studio simulator developed the breast model.

Microwave Breast Cancer Detection

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Worldwide, breast cancer continues to be the top cause of death among women and the second-leading cause of cancer death after lung cancer. Thus, it has become a great global concern. Years of research on both diagnostic and therapeutic breast cancer detection and imaging using microwave techniques has resulted in a variety of novel approaches and studies. These approaches and studies utilize numerical breast phantoms that model structural complexities, tissue heterogeneity, and dispersive dielectric properties. In this dissertation, a microwave breast cancer detection technique was investigated and Ultra-Wide Band (UWB) radar imaging was used. A UWB antenna was designed and modeled using CST Microwave Studio and was used for Ultra-Wide Band microwave breast cancer detection. A new calibration approach for microwave breast cancer detection was proposed to calibrate the signals before applying the beamforming algorithms. A simulation was also used to validate the proposed techniques. Two signal calibration approaches were proposed to remove the high magnitude clutter from the signals. The two approaches are based on the state-space method Autoregressive Moving Average (ARMA). The first approach is derived from Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT). This algorithm is referred to as the Pole Isolation via ESPRIT algorithm (PI-ESPRIT). The second approach is also derived from a previously proposed algorithm for microwave breast cancer detection. Th second calibration algorithm is referred to as the Modified Pole Removal algorithm. The Modified Pole Removal algorithm works to detect tumors, in contrast to the previously proposed algorithm (Pole Removal) that shows a lack of tumor detection. Three beamforming techniques were used to focus the signals onto the voxels through the breast phantom. Another beamforming algorithm was proposed, along with the Transmitting-Receiving Antenna Separation Distance (TRASD), which allows for the reduction of the late time clutter effect and improvement of the Signal to Clutter Ratio (SCR) when using the PI-ESPRIT algorithm. Using CST simulation tool, antennas arrayed around the breast are designed to simulate the transmitting/receiving signals. Numerical phantoms, with complicated structures and dispersive dielectric properties of breast tissue, have been developed with the CST simulation tool for simulating electromagnetic propagation. The received signals are imported into the MATLAB program to investigate the proposed approaches and compare them to conventional approaches. Overall, the results have shown improvement.

AbstractA dual band-notched MIMO/Diversity antenna is proposed in this paper. The proposed antenna ensures notches in WiMAX band (3.3–3.6 GHz) besides WLAN band (5–6 GHz). Mushroom Electromagnetic Band Gap (EBG) arrangements are employed for discarding interfering frequencies. The procedure followed to attain notches is antenna shape independent with established formulas. The electromagnetic coupling among two narrowly set apart Ultra-Wide Band (UWB) monopoles is reduced by means of decoupling bands and slotted ground plane. Monopoles are 90° angularly parted with steps on the radiator. This aids to diminish mutual coupling and also adds in the direction of impedance matching by long current route. S

Abstract A Co-Planar Waveguide fed circular ultra-wide band antenna with modified ground-plane and feedline is designed on a FR4 (ϵr=4.3) substrate of thickness 0.01λ0. The proposed antenna exhibits an overall impedance bandwidth ranging from 2.99 GHz to 18.0 GHz and beyond (with S11< -10 dB). Design parameters have been optimized to achieve the UWB bandwidth. The measured radiation patterns of this antenna are omnidirectional in H- plane and bidirectional in E-plane. An extended impedance bandwidth is achieved as a result of modified feed-line. The proposed antenna can be used for medical imaging and urban IoT applications.
