dc.description.abstractIn the lower millimetre-wave frequency range, Substrate Integrated Waveguide (SIW) circuits have emerged as a reasonable compromise between rectangular waveguide and standard microstrip technologies. They are formed by a top- and bottom-metalized substrate and two arrays of plated or riveted holes (via holes) to replace the vertical metallic walls in conventional rectangular waveguide. Although many passive components known from traditional waveguide technology have been fabricated in SIW, one of the main challenges is to integrate active components with typical coaxial-type interfaces within the SIW environment. Therefore, the work presented in this dissertation focuses on new broadband transitions from SIW to other planar transmission-line technologies such as microstrip coplanar waveguide, coplanar strip line, slot line and coupled microstrips. Several of the new transitions are prototyped and experimentally verified. Two of these transitions are then used to integrate a low noise amplifier within SIW input and output ports. The measurements of fabricated SIW amplifier prototypes show very promising performance and clearly demonstrate successful integrations of active components within SIW. Finally, one of the new SIW-to-coplanar-waveguide transitions is employed as an interface to an SIW-based antenna, thus demonstrating the principle of connectivity of SIW to all currently used planar circuit technologies.en_US
