【摘要】：左手材料由于其獨特的電磁特性,近些年已經成為電磁領域熱門的研究課題之一。然而,目前對于左手傳輸線的研究還處于探索階段,還有很多理論與實踐的工作需要補充。本文在對CMOS傳輸線波導特性進行詳細分析的基礎上,設計并制作了基于雙重行為(Dual-Behavior)諧振器的帶通濾波器與右手梳狀濾波器,基于左手傳輸線的雙通帶濾波器、梳狀濾波器與雙模濾波器。首先,通過對CMOS工藝中的傳統(tǒng)微帶傳輸線與人工合成的互補傳導傳輸線的波導特性的萃取,論證了運用CMOS工藝制作太赫茲濾波器的可行性,并設計制作了基于雙重行為諧振器的帶通濾波器與右手梳狀濾波器。其次,本文提出了一種新型的雙通帶諧振器,以及基于該諧振器的雙通帶濾波器。該雙通帶諧振器由開路的左手傳輸線與開路右手傳輸線并聯(lián)構成,在此諧振器中,開路右手傳輸線在其四分之波長頻率處引入一個傳輸零點;左手傳輸線在其電角度小于π/4時,與右手傳輸線形成并聯(lián)諧振,引入傳輸極點;在其電角度為π/4與π/2時分別等效為串聯(lián)諧振和并聯(lián)諧振,引入傳輸零點與傳輸極點;左手傳輸線自身的高通波導特性,可以濾除不需要的低頻信號。此外,左手傳輸線具有較大的慢波系數,這極大地縮小了諧振器的尺寸。再次,本文提出了基于左手傳輸線的梳狀濾波器架構。與傳統(tǒng)的基于右手傳輸線的梳狀濾波器相比,左手梳狀濾波器的諧振器中的左手傳輸線一側加載接地電容,而另一側開路。通過對加載負載電容的左手諧振器的諧振特性、左手諧振器之間的耦合特性、以及左手梳狀濾波器的輸入/輸出耦合結構的系統(tǒng)分析,詳細闡述了左手梳狀濾波器的設計方法。同時,由于左手傳輸線的獨特波導特性,左手梳狀濾波器的寄生通帶位于其主通帶的低頻側。最后,本文提出了基于左手傳輸線的雙模濾波器架構。該左手雙模濾波器工作于負階諧振模式。左手環(huán)形諧振器的諧振頻率可以由左手傳輸線的波導特性、左手傳輸線單元結構的周期、以及諧振器中所包含的單元結構的數目計算得到。左手環(huán)形諧振器的雙模特性可以通過調節(jié)微擾電容大小、微擾電感長度與插入右手傳輸線來激發(fā)。本文還對左手環(huán)形諧振器的電流分布進行了研究。在進行濾波器設計時,為了獲得較大的耦合系數,本文將三種微擾方式有機的結合在一起,制作出了具有傳統(tǒng)右手雙模濾波器很難實現(xiàn)的帶寬的雙模濾波器。
[Abstract]:The left hand material because of its unique electromagnetic properties, in recent years has become one of the hot topics in electromagnetic fields. However, current studies on the left-handed transmission line is still in the exploratory stage, there are many theoretical and practical work needs to be added. This paper detailed analysis of CMOS waveguide transmission line characteristic, designed and fabricated based on double act (Dual-Behavior) band-pass filter and comb filter resonators of the right hand, left hand transmission line Dual Band Bandpass Filter Based on comb filter with dual mode filter. Firstly, extraction by traditional waveguide microstrip transmission line of CMOS technology and synthesis of the complementary transmission transmission line, demonstrates the feasibility of making use of terahertz filter CMOS process, making the band-pass filter and the right hand comb filter design based on dual behavior resonator. And secondly, this paper. A new type of dual band resonator, the resonator and the double pass band filter. Based on the dual band resonator composed of left-handed transmission lines open and open the right hand transmission line connected in parallel, the resonator, open the right hand transmission line at a wavelength of four frequency into a transmission zero; left-handed transmission line the electrical angle is less than /4, the formation of resonance with a right-handed transmission line is introduced in the power transmission pole; angle /4 and Pi Pi /2 were equivalent to the series and parallel resonant, introducing the transmission zeros and poles; high pass waveguide characteristics of left-handed transmission line itself, can filter the low frequency signal. In addition, the left hand transmission line with slow wave coefficient, which greatly reduces the dimensions of the resonator. Thirdly, proposed a comb filter architecture based on left-handed transmission line. With the traditional right-handed transmission line based on the The left hand side comb filter compared to transmission line loading left comb filter resonators in the grounded capacitor, and the other side of the open circuit. Through the resonant characteristics of the resonator loaded the capacitance of the left hand, left hand coupling between the resonators, and the analysis of the system left comb filter input / output coupling structure, elaborates the design method of the left hand comb filter. At the same time, due to the unique optical properties of left-handed transmission line, parasitic left comb filter pass band is located in the main through low frequency side band. Finally, the proposed dual-mode filter architecture based on left-handed transmission line. The left hand dual-mode filters work in a negative order resonant modes. Waveguide resonant frequency of left ring resonator the left-handed transmission line cycle, left-handed transmission line unit structure, and the number of elements contained in the resonator structure calculation Get a dual-mode ring resonator. Left-handed properties can be adjusted by the perturbation capacitance, inductance and micro disturbance insert right-handed transmission line length to inspire. The left hand ring resonator is studied. The current distribution in the filter design, in order to obtain a large coupling coefficient, the three perturbation mode combination together, making a dual-mode filter is difficult to achieve with traditional right dual-mode filter bandwidth.
