Abstract:

Frequency Selective Surfaces (FSYs), which are commonly used in the fields of wireless communication, microwave and radar systems, are widely designed as two-dimensional (2D) flat structures. In this study, a new three-dimensional (3D) FSY is recommended with more flexible features containing the eight-gen-shaped conductor circle for 10 GHz, which is the X-band center frequency. The effect of the transmitter height change is being studied and the results are discussed by analysing the unit cell parameters for 3D FSY. The analysis was carried out with the computer simulation technology (CST) program. With the increase in the height of the eight-shaped conductor wing located in the unit cell of the designed 3D FSY, it has been shown that the structure periodically stopping the band and passing the band filter characteristics in the X-band. Parameters analysis found that value increases in unit cell parameters outside the conductor height lowered the resonance frequency. In the TE mode, with the increase of the wave's point of entry, the resonance frequency increases and the bandwidth decreases. In the TM mode, the frequency reaction is stable and the bandwidth increases with the increase in the point of entry.
