Surface selective frequency reconfigurable based on the geometry of the four star arms.

摘要

The present invention which, in only one element, combines the functions of implementing a frequency selective surface, with the intention of incorporating the characteristics of low construction cost,To convey large amounts of information at the same time, operating at different frequencies without interference or obstruction between the services offered.As the elements of programmable control with feedback to increase the rate of transfer, reduce errors and noises, and block the signals to increase security.Came the idea to develop a reconfigurable frequency selective surface in.The frequency selective surface formed by a periodic arrangement of printed on a dielectric substrate with dielectric constant Sr (1), the geometry of symmetric star four arms (2),Containing 25 cells, 5 x 5 elements, the upper edge (3) and lower in each line of single cells (4), a crack in the center of each cell (5),Supply lines to serve as a point of connection (6) to serve as a connection point of the power supply and diodes pin (7).
