The electrodynamic characteristics of frequency-selective surfaces with aperture elements in the form of Jerusalem's and Evangelist's crosses have been determined by using the finite element method. Influence of sizes of aperture elements on resonance frequencies, attenuation and pass-band width of mesh filters on their basis has been investigated. The surface dimensions providing narrow-band filtration of signals near the central frequency 90 GHz have been found numerically. Comparison analysis of considered structures has been carried out.
