The FSS structure shows the effect of on WIFI signal by
increasing the signal power. All of the signal power was
increasing when the FSS structure was attached WIFI device.
This FSS structure can be attach with the WLAN device at
certain blind-spot with low wireless coverage, and the effect is
expected to solve the low signal power problem. In future work,
FSS structure will design multiple frequencies band for
multiple applications. This FSS structure is safe to use, do no
need electricity, and easy to use.
