dc.description.abstractENGLISH ABSTRACT: This dissertation will present the following two topics: (1) Implementation of a waffle-iron filter, utilising multi-layered substrate integrated waveguide (MSIW) technology and (2) Developing a new methodology for measuring scattering parameters of multimode waveguide filters. The classical image impedance synthesis method for waffle-iron filter design is used to develop two filters. Filter A is a classical MSIW Waffle-iron filter and filter B is an extended version with an extra step in the middle of the filter. This work proposes two methods in measuring a multimode waveguide filter; one utilising a set of measurements with different probe positions, and one using a radiating horn. The prototypes presented, displays less than -12 dB passband reflection over 8.5 to 10.5 GHz, with stopband attenuation in excess of 70 dB over the harmonic bands 15 to 43 GHz for filter A and 15 to 48 GHz for filter B. The prototypes were designed to handle 10 Watt average power in the transmitted band. A good correlation is found between synthesised and measured responses in these two designs.en_ZA
