Modeling and Design of Frequency Selective Surface for GSM and UMTS Frequency Bands

Abstract

In this paper, frequency selective surfaces (FSSs) are analyzed and designed. The simulation and analysis of different configurations of loop elements based FSS is proposed. A simple technique of Single-Square-Loop frequency selective surface (SSL-FSS) is used. The process of the calculation of various parameters is presented and the numerical technique has been supported by the simulation. The simulations of microstructure are performed with full wave simulation tool CST- Microwave Studio on single substrate for different physical parameters. The results show that the transmission improvement at 900 MHz, 1800 MHz and 2100 MHz of GSM and UMTS frequency bands. Regardless of unknown electric characteristic of aluminum and substrate, the transmission curve of free standing Triple Square Loop FSS, it has three band pass response with center frequency 945 MHz, 1785 MHz and 2.4GHz.
