摘要

為了在毫米波段提供5GH 頻寬的高速通訊，本論文將針對60GHz 和
70GHz 頻段來設計帶通濾波器。
在本論文中，所使用的設計結構包含兩種。第一種為矩形環結構，此結構可以自動產生兩個傳輸零點，而且會有較大的頻寬，但是並不適用於窄頻的應用。第二種則是基板合成波導共振腔結構，利用基板合成波導優秀的特性來設計共振腔濾波器，此架構可以設計較窄頻寬。在此架構內加入並聯的共平面波導傳輸線可以產生額外的傳輸零點。此兩種架構都製作在低溫共燒陶瓷基板上，但僅有基板合成波導共振腔結構製作在氧化鋁基板上。目前所設計濾波器，除了LTCC 60GHz 以外，其輸入阻抗皆小於2.8 dB。而矩形環結構的頻寬為21.35%，基板合成波導共振腔結構的頻寬為6.8%。

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.
In 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 an
additional transmission zero. We make these two structures on the LTCC substrate. But only the second structure is made on the alumina substrate. Besides the LTCC
60GHz 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 structure
BPFs are 6.8%
