碩士 === 國立臺南大學 === 電機工程研究所 === 99 === In this thesis, the radio frequency bandpass filters for UWB、WLAN and WiMAX applications are designed and fabricated based on the Metamaterial structure. The design and implementation of 26-/60-GHz and 60-/110-GHz millimeter-wave CMOS dual-band on-chip bandpass filters are also included in this thesis. A novel UWB bandpass filter (BPF) based on the composite right/left-handed (CRLH) material and 0° feeding structure is proposed. Two types of dual-band BPFs centered at 2.45-GHz/3.5-GHz and 2.45-GHz/5.2-GHz for WIMAX and WLAN applications were fabricated and measured. Also, a miniaturized planar tri-band filter using the embedded metamaterial resonators (EMRs) has been demonstrated. The three transmission bands centered at 2.45, 3.5, and 5.7 GHz can be excited and designed.Besides, the 26-/60-GHz millimeter-wave CMOS dual-band filter using CRLH structure has been designed and measured. The insertion losses at the frequencies 26 and 60 GHz are 3.2 and 5.3 dB, the return losses at the frequencies 26 and 60 GHz are 10.9 and 6.7 dB, the transmission zeros are located 45-GHz and 67-GHz, respectively. In the study of a 60-/110-GHz millimeter-wave CMOS dual-band on-chip bandpass filter, the dual-feed structure is presented to control the external quality factors of the first and second bands. Such an approach leads to a significant reduction for the on-chip area. Also, the frequency selectivity and impedance matching are further improved. The insertion losses at the frequencies 60 and 110 GHz are 3.5 and 3.4 dB, the return losses at the frequencies 60 and 110 GHz are smaller than 12.5dB, the transmission zeros are located 42-GHz, 87-GHz and 175-GHz, respectively.
