Abstract
There are many allocated frequency band can provide a bandwidth of more than 5 GHz to realize high speed communication up to 2Ghps to 4Ghps. This thesis presents the design of bandpass filters on 60GHz-band and 70GHz-band.
In this thesis, we design several coupling resonant bandpass filters for 60GHz-band and 70GHz-band by the substrate integrated waveguide (SIW) cavity structure on the LTCC and alumina substrate. And then we add shunt CPW lines to introduce a transmission zero. The lowest insertion loss of these filters is less than 2.8 dB, and the return loss is higher than 15 dB except the filter with transmission zero. There will be a second passband due to the high order mode of the cavity if we design filters by the substrate integrated waveguide cavity structure.
