摘要：

A frequency selective surface (FSS) based on hexagon substrate integrated waveguide (HSIW) technology is proposed in this letter and designed at the center frequency of 140 GHz. The periodic element comprises a HSIW cavity and two circular slots etched on the top and bottom conductor claddings of the cavity. Based on the hexagon cavity, this type of FSS has a better polarization stability and a closer element arrangement compared with square cavity FSS and circular cavity FSS, respectively. Besides, circular slots are better than polygonal slots which have round corners at their corners when fabricated using normal printed circuit board process. Thus, the HSIW FSS can achieve a good and stable performance at terahertz band. The proposed structure is fabricated and the measured result has a good agreement with the simulated one.
