Microwave seminar | 27 June 2022

During the past few years, microwave-sensing systems have grown rapidly in numbers and capabilities mainly due to their different advantages. The sensing capabilities of the different microwave sensors mainly rely on the resonance principle. For that, different materials and methods are attracting increasing interest in several applications due to the strong potential for detection and sensing applications in medicine, health care, telecommunication and environmental monitoring.

In fact, microwave sensors using microstrip antennas have great potential in the field of sensors because of their lower cost, portability, sensitivity, simple fabrication process, and instant measurements.
In this context, the question of the UWB/body interaction antenna naturally arose, particularly in the medical field. The emerging microwave imaging techniques gives better results with the advantages of non-ionizing, comfortable, and sensitive to specific malignancies. In addition, the development of UWB microstrip patch antennas is shown to reduce cluttered data to produce highly localized images. Also, it allows addressing the problems related to the variability of dosimetry in electromagnetism.
