Abstract

Frequency selective surfaces (FSS) consisting of periodic arrays of conducting patches deposited on dielectric layers, excited by incident plane waves, are used in the development of several microwave and millimeter-wave devices. The scattering parameters of FSS structures consisting of periodic arrays of thin dipoles and crossed dipoles on a dielectric anisotropic layer are investigated in the spectral domain. Numerical results are obtained as a function of the structural parameters for oblique incidence. It is observed that the use of anisotropic substrates increases the design flexibility of FSS structures on a dielectric layer. The analyzed structure can be used in the development of wideband microwave devices, such as microwave filters.
