In this paper two novel C-shaped Defected Ground Structures (DGSs) on a microstrip line is proposed to provide a frequency rejection property with a very high Q-factor. The new structures are compact and have a simple shape. Their rejection properties have a sharp transition at stop band and they provide very low insertion loss in pass band. Different parameters of the DGS have been adjusted for the...

A compact, small size dual band-stop C-shaped defected ground structure (DGS) is proposed in this paper. Two similar C-shaped patterned ground structures are designed and their dimensions are adjusted to obtain band rejection frequency response at 2.4 GHz and 6.7 GHz. Then, two DGSs structure are cascaded in series to obtain a high Q-factor dual-band rejection property. The distance between two DGSs...
In this paper, we present a method to estimate the special points with the most motion in two neighbor frames. We propose a solution to determine the best illumination of either a static object, and a moving camera, either or a moving object and a static camera with two different issues: maximizing the brightness of the scene and maximizing the contrast in the image. The role of gradient estimation...
