Abstract:This paper presents a Frequency Selective Surface (FSS) based sensor for temperature sensing. The proposed sensor operates in Ku-band and measures changes in temperature using a rectangular patch-based unit cell that includes a conductor backed temperature-sensitive substrate. Changes in temperature are sensed by monitoring the change in resonant frequency of the FSS when interrogated by an incident electromagnetic signal linearly polarized parallel to the long dimension of the rectangular patch element.
