Design for the structural surface material enabling shielding for interference mitigation within the buildings in the unlicensed 2.4ghz ISM band

摘要

This work is proposed to design shielding for interference mitigation and network security within the buildings in the unlicensed 2.4GHz ISM band and to provide maximum transparency at broadcast frequencies. Thus, mobile phones, radio and television signals in buildings will not be affected. Frequency Selective Surface (FSS) is attached onto existing common construction material to transform the standard material into a band stop frequency selective wall. To obtain the band response of FSS having a desired frequency interval, a new FSS periodic element geometry is introduced. The obtained results show that desired frequency response is achieved. HFSS software is used for simulation purposes.
