With the renewed applications of millimeter wave technologies in remote sensing, radio astronomy, and quasi‐optical (QO) systems have been widely used in various radiometer systems. Frequency selective surface (FSS) is one of the key components in a QO system, functioning as frequency separation. For a practical FSS component, small insertion loss and narrow transition band from pass band to stop band are preferred to maintain signal level and reject out‐of‐band noise, respectively. In addition, the bandwidth is also a concerned parameter. In this article, perforated array is used for the design and fabrication of FSS for a dual‐channel QO system. The agreement between measurement and simulation is satisfactory. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2365–2369, 2014
