Abstract
In order to provide the high speed communication with 5GHz bandwidth, this thesis focus on the design of 60GHz-band and 70GHz-band bandpass filters.n this thesis, there are two design structures. The first one is a rectangular ring structure. This structure can create two transmission zeros and have large bandwidth. But this structure is not suitable for the narrowband bandpass filter. The second one is using substrate integrated waveguide (SIW) cavity structure with coupled resonators. Because of the low loss of SIW, we can design SIW filter well. This structure can make the narrowband bandpass filter. Adding the shut CPW lines can introduce andditional transmission zero. We make these two structures on the LTCC substrate. But only the second structure is made on the alumina substrate. Besides the LTCC0GHz BPF, the insertion loss are less than 2.8dB for all filters. The bandwidth of the rectangular ring structure BPF is 21.35%. And the bandwidth of SIW cavity structurePFs are 6.8%
