High performance frequency selective surfaces (FSSs) have a myriad of applications in the advanced sensor, radar, and communication systems. The most common FSS is a twodimensional (2D) periodic array of thin conducting or aperture elements etched on a flat or curved dielectric surface. This structure usually exhibits a frequency filtering characteristics similar to the frequency filters in traditional radio-frequency (RF) circuits. In this seminar, we’ll review and discuss various multi-band FSS used in the multi-band communication systems. Specifically, we’ll first discuss the resonant frequency stability feature of the FSS with single or double fractal elements. Then its applications in multi-band Satellite or Wireless Communication systems will be described. Finally, the FSS with split-ring-resonator (SRR) elements will be introduced and applied to the multi-function phased array antenna systems.
