Abstract
In this thesis, a third-order surface-mount substrate-integrated waveguide (SIW) filter and its design methodology are presented. The proposed filter has the center frequency of 39.3 GHz and bandwidth of 1.5 GHz. The filter is composed of a single dielectric substrate and it utilizes TE10 mode of the rectangular resonators. For the design of the filter, the synthesis of a coupling matrix using an optimization algorithm is presented. The external coupling structure is located between the grounded coplanar waveguide (GCPW) and the resonator, and the inter-resonator couplings are achieved using a post-wall inductive iris structure. Since the filter is intended to be mounted on a motherboard, the input and output ports are designed such that they are compatible with the microstrip line of the motherboard. Unexpected resonances appear in the lower stopband when the filter is mounted on the motherboard without suppressing structures, which deteriorates the attenuation performance of the filter. A practical suppressing technique is proposed to eliminate the undesired resonance. For verification of the proposed design method, a filter and motherboard have been designed, fabricated and measured. The measurement results are in good agreement with the simulation results.
