We introduce a novel system for collecting near-field scattering data. The system utilizes a combination of rectangular waveguides and printed-circuit-boards, consisting of several field collection slots. Data collection is based on the modulated scattering technique. A prototype system using four waveguides was fabricated and tested in both air and water. Simulation and measurement results show that...
A printed elliptical monopole antenna is proposed for biomedical imaging application. The antenna is designed to operate at 2–9 GHz. For efficiency coupling of the microwave signal to the breast, a coupling medium (canola oil) is chosen having permittivity of 3. This also helps in miniaturizing the antenna size. Glycerin (εr = 9) is used as the breast phantom material. The antenna parameters are optimized...
The design of a double-ridged horn antenna for medical imaging is presented in this paper. The antenna is immersed in canola oil to reduce its size and to achieve efficient coupling of the electromagnetic energy to the breast tissue. The antenna has wideband performance from 1.5 GHz to 5 GHz (3.5 GHz or 108% of impedance bandwidth), which is suitable for radar-based medical imaging. The double-ridged...
The design of a miniaturized double-ridged horn antenna for use as an array element in the Subsurface Radar (SR) system is presented. The array antenna system will be arranged in a cylindrical scanning geometry which will host 72 antennas in a row for illuminating the target and receiving scattered signal. The scanning system will have several rows of antennas for better sensitivity and spatial accuracy...
