A New Miniaturized Double Stop-band Frequency Selective Surface.

A miniaturized double stop-band FSS for WLAN was proposed based on the structure of a ring patch with internal branches and a cross zigzag loaded line. This construction is obtained by using the multilayer connection method to paint the two layers of the patch that we designed on the top and bottom of the dielectric substrate to simulate the designed construction by using HFSS simulation. Analyzing the frequency response characteristics of the FSS indicates that the construction can generate two transmission band gaps at 1.92-2.17 GHz and 4.94-5.99 GHz in the WLAN wave. This construction has stronger polarization stability and angle stability when the incident electromagnetic wave is 0-60°. It also has a simple construction, small size, and significant engineering application value. [ABSTRACT FROM AUTHOR]
