18. Gap Waveguide for High Frequency Microwave Application- Validation of Concept, Filter Design & Packaging Aspects
Sammanfattning : The overall goal of this thesis is to validate the low loss performance of recently evolved gap waveguide technology and to use this low loss technology for designing critical passive microwave component such as narrow band filter. Also, the exploitation of gap waveguide concept as a packaging solution for densely packed RF circuitry has been presented in this thesis. LÄS MER
19. Gap Waveguide: Low Loss Microwave Passive Components and MMIC Packaging Technique for High Frequency Applications
Sammanfattning : The heavy congestion at the existing radio frequency spectrum allocated for the today’s wireless communications motivates and accelerates the research work at mmWave bands or even higher frequency range where more spectrum space is available for massive data rate delivery. The inclination of modern wireless system research and development is towards small size, reliable, high-performance and high-yield microwave multifunctional products. LÄS MER
20. An FRA Transformer Model with Application on Time Domain Reflectometry
Sammanfattning : Frequency response analysis (FRA) is a frequency-domain method which is used to detect mechanical faults in transformers. The frequency response of a transformer is determined by its geometry and material properties, and it can be considered as the transformer’s fingerprint. LÄS MER
