Analysis of band pass filter printed on isotropic and anisotropic substrates by the WCIP method

This work presents the frequency response analysis of a planar band pass filter using the WCIP method. The filter geometry is composed of a rectangular microstrip patch with a perforated complementary split ring resonator (CSRR). The investigation of the filter properties is done considering the perforated patch geometry printed on isotropic and anisotropic substrates. Simulations results are determined by WCIP method and HFSS software, for comparison purpose, for the filter resonant frequency, bandwidth, return loss, and insertion loss. A prototype of the proposed band pass filter printed on isotropic substrate was fabricated and measured. Simulation (WCIP and HFSS) and measurement results are in good agreement.
