In this work, we prepared a fluorescent film comprised phosphors and silicone on flexible polyethylene terephthalate (PET) substrate using a screen printing technology.The effects of mesh number and weight ratio of phosphors to silicone on the optical properties of the flexible films were investigated.The results indicate that the emission intensit
Abstract Space-fed array comprising of E-shape or U-slot cut rectangular microstrip Cleaning antennas using the modified feed designs are proposed for higher gain and wider bandwidth.Modified feed optimally illuminates the edge space-fed elements to achieve a maximum gain.Amongst the two space-fed array variations, 7 x 7 E-shape space-fed array, ex
