【摘要】：基于基片集成波導(dǎo)(Substrate Integrated Waveguide,SIW)的濾波器相比波導(dǎo)濾波器具備傳輸損耗小、Q值高、尺寸小、造價低的優(yōu)點,相比微帶結(jié)構(gòu)的濾波器,彌補(bǔ)了其在高頻段的不足。本文研究了基片集成波導(dǎo)濾波器的設(shè)計原理和方法,提出了高選擇性、低插入損耗、小型化和高集成度的新型濾波器結(jié)構(gòu)。歸納起來,本文的工作包括以下幾個方面:1)提出新型的單腔體寬帶濾波器。利用基片集成波導(dǎo)腔體結(jié)構(gòu)中的三種模式TE101模、TE102模和TE201模,通過加載金屬化通孔和表面縫隙實現(xiàn)模式頻率的擾動,完成寬帶濾波。2)提出利用基片集成波導(dǎo)諧振腔中平衡諧振模式構(gòu)建平衡式雙通帶濾波器。采用矩形諧振腔中TE102模和TE201模來構(gòu)建平衡濾波器的雙通帶,設(shè)計新穎的內(nèi)部耦合結(jié)構(gòu)引入源和負(fù)載之間的耦合,產(chǎn)生兩個額外傳輸零點,改善了帶外抑制性能,同時共模抑制性能達(dá)到35dB以上。3)提出基于QMISW和EMSIW諧振腔的新型小型化濾波器設(shè)計方法。首先設(shè)計了三階切比雪夫濾波器;之后構(gòu)建新型饋電和耦合結(jié)構(gòu),通過引入源和負(fù)載之間的耦合,設(shè)計了具有四個傳輸零點的高選擇性單通帶小型化濾波器;最后設(shè)計了雙通帶濾波器。
[Abstract]:Compared with waveguide filter, the filter based on substrate Integrated waveguide siw has the advantages of high transmission loss, small size and low cost, compared with microstrip filter. In this paper, the design principle and method of substrate integrated waveguide filter are studied, and a new filter structure with high selectivity, low insertion loss, miniaturization and high integration is proposed. The work of this paper includes the following aspects: 1) A novel single-cavity wideband filter is proposed. The three modes of TE101 mode TE102 and TE201 modes in waveguide cavity structure are integrated with substrates. The mode frequency is disturbed by loading metallized through holes and surface gaps. Complete wideband filter. 2) A balanced double pass band filter is proposed by using the balanced resonant mode in the substrate integrated waveguide resonator. The TE102 mode and the TE201 mode in the rectangular resonator are used to construct the double pass band of the balanced filter. A novel internal coupling structure is designed to introduce the coupling between the source and the load, resulting in two additional transmissions of 00:00, which improves the out-of-band suppression performance. At the same time, the common mode suppression performance is over 35dB. 3) A novel miniaturized filter design method based on QMISW and EMSIW resonators is proposed. First, a third-order Chebyshev filter is designed, then a novel feed and coupling structure is constructed. By introducing the coupling between the source and the load, a highly selective single-pass band miniaturized filter with four transmission 00:00 is designed, and a double-pass band filter is designed.
