Ultra-wideband planar antenna design using spintronic microwave sensors

Microwave imaging has gained interest in biomedical imaging because of its non-ionizing and non destructive approach. It will be quick, comfortable and cheap compared to current imaging modalities available such as X-ray tomography and magnetic resonance imaging (MRI). In microwave imaging, the major challenge is the design of microwave sensors for receiving scattered signal from the target. For effective signal penetration, the frequency of operation has to be low (below 7 GHz), and at this frequency, the sensor size becomes large. The use of spintronics sensors is proposed instead of microwave sensors, which will be a break-through in the microwave imaging technology area, if a successful implementation of a is possible. It requires high-performance, miniaturized ultra-wideband antennas to illuminate the target. The scattered signals will be picked up by the spintronics sensors for reproducing the image. The partner organization is interested in optimization process and image reconstruction algorithm for clinical application. The organization will have the opportunity to collaborate with the University for a clinical system design and develop a new imaging technique which will be beneficial for Canada and the world.
