Investigations on some planar microwave filters

Krishna, Katta Saran (2014) Investigations on some planar microwave filters. MTech thesis.



Filters are substantial microwave components. RF/Microwave filters can be implemented using transmission lines. In this thesis microstrip bandpass filters had been designed for RF/microwave applications. Some novel techniques like implementing the open split koch loop resonators, open split square loop resonators, and star shaped multi-mode resonators are implemented in designing the microstrip bandpass filters. Microstrip filters are used in this report to design bandpass filters because of their compact sizes. The goal of this thesis is to investigate on some planar microwave bandpass filters. In this thesis four novel compact bandpass filters has been designed and simulated, specifically three pole koch resonator, seven pole koch resonator, three pole square loop resonator and compact UWB bandpass filter using MMR. The design and simulation of each and every filter is given in detail with including all the required specifications. From the previous research studies it is evident that, to design a good bandpass filter there should be a smooth passband and good stopband with higher insertion loss in the stopband. The four designs which are explained in this thesis has these important factors, which makes these filters useful for the microwave applications.
