| Tiivistelmä (eng): | In this thesis the propagation characteristics of non-radiating dielectric waveguides (NRD guide) and its feasibility for end-fire and leaky-wave antenna structures in the W frequency band were studied. To obtain the propagation constant, MARCATILI's approximation method was extended to be used with NRD guides and the outcome was verified with simulation results. In order to connect the NRD guide to standard metal waveguides a new direct connection transition was developed and a prototype was manufactured and measured. Based on the concept of a dielectric rod waveguide antenna an NRD guide end-fire antenna is presented and verified experimentally based on the same experimental NRD guide used for the transition. Furthermore a concept for a new type of periodic leaky-wave antenna based on the NRD guide is presented, where high impedance surfaces allow the radiated electromagnetic wave to propagate out of the waveguide structure. |
