Band Pass

In telecommunication, filters are often used to pass the desired frequency. One of them is the Band-Pass Filter (BPF) which is passing signals between the upper cut-off frequency and the lower cut-off frequency. This research aims to make a band-pass filter that can pass 3 GHz frequency with a bandwidth of 200 MHz. This filter is designed with a square open-loop resonator simulated using Advanced Design System (ADS) software. The filter is made using FR 4-epoxy substrates with a dielectric constant (ε ) of 4.6 and substrate thickness (h) of 1.6 mm. Based on the simulation results obtained in the form of a comparison graph between the response of magnitude to frequency, it shows that the value of the return loss (S 11 ) parameter of -23.549 dB, insertion loss (S 21 ) parameter value of -1.397 dB, and a slightly shifted middle frequency of 2.890 GHz. Then for the measurement results obtained a parameter value return loss (S 11 ) of -16.364 dB, parameter value insertion loss (S 21 ) of -3.561 dB with a center frequency of 3.185 GHz.

Radar is an important component for people. A number of functions could be taken into account on a various aspect in term of quantifying the distance of a specific object, developing a map, and/ or forecasting climate. Generally, one of the main instruments within a radar is a filter. The aim of this study is to design a simple Band Pass Filter which able to be effectively worked on frequency 2.75–2.85 GHz. The filter is designed at the mid frequency of 2.8 GHz with ≤ -20 dB of Return Loss Range, ≥ -3 dB for Insertion Loss, and 100 MHz for Bandwidth, then it is manufactured into a Square Open-Loop Resonator microstrip. The filter uses Rogers R04035B for its substrate with 3.48 of Dielectric Constant Values  and 1.524 mm of Substrate Thickness (h).

Short range radar (SRR) uses the K-band frequency range in its application. The radar requires high-resolution, so the applied frequency is 1 GHz wide. The filter is one of the devices used to ensure only a predetermined frequency is received by the radar system. This device must have a wide operating bandwidth to meet the specification of the radar. In this paper, a band pass filter (BPF) is proposed. It is designed and fabricated on RO4003C substrate using the substrate integrated waveguide (SIW) technique, results in a wide bandwidth at the K-band frequency that centered at 24 GHz. Besides the bandwidth analysis, the analysis of the insertion loss, the return loss, and the dimension are also reported. The simulated results of the bandpass filter are: VSWR of 1.0308, a return loss of -36.9344 dB, and an insertion loss of -0.6695 dB. The measurement results show that the design obtains a VSWR of 2.067, a return loss of -8.136 dB, and an insertion loss of -4.316  dB. While, it is obtained that the bandwidth is reduced by about 50% compared with the simulation. The result differences between simulation and measurement are mainly due to the imperfect fabrication process.

In this study, the proposed bandpass filter (BPF) connects an interdigital and a spiral capacitor in series between the two symmetrical halves of a circular intertwined spiral inductor. For the mass production of devices and to achieve a higher accuracy and a better performance compared with other passive technologies, we used integrated passive device (IPD) technology. IPD has been widely used to realize compact BPFs and achieve the abovementioned. The center frequency of the proposed BPF is 1.96 GHz, and the return loss, insertion loss and transmission zero are 26.77 dB, 0.27 dB and 38.12 dB, respectively. The overall dimensions of BPFs manufactured using IPD technology are 984 × 800 μ m 2 , which is advantageous for miniaturization and integration.

Riset bandpass filter telah mengalami perjalanan panjang, seiring dengan perkembangan teknologi wireless dan aplikasi sensor serta radar. Sampai dengan pertengahan 2015 ditemukan sangat banyak riset tentang bandpass filter di pelbagai publikasi yang ada. Dasar perancangan bandpass filter didominasi dengan metoda insertion loss yang menggunakan aproksimasi Butterworth, Chebyshev dan Elliptis. Realisasi dari elemen yang muncul dari aproksimasi di atas diimplementasikan dalam bentuk penggandengan beberapa resonator. Resonator yang tergandeng ujung (end-coupled) dan tergandeng parallel (parallel-coupled) memberikan realisasi fisik dari penggandengan langsung, sedangkan untuk penggandengan silang digunakan open-loop resonator. Modifikasi filter dengan open-loop resonator digunakan untuk merancang dual bandpass filter dengan mengorbankan hilangnya transmission zeros.

Recently, a multilayer structure is very imperative to minimize the size of planar microstrip filters. In the flexible design and incorporation of other microwave components, a multilayer band-pass filter provides another dimension. This paper, therefore, introduces a band-pass filter of 2.52-2.65 GHz for digital broadcast applications using parallel-coupled line (PCL) and multilayer(ML) hairpin resonator. The targeted four-pole resonator has a center frequency of 2.58 GHz with a bandwidth of 130 MHz. The hairpin-line offers compact filter design structures. The proposed configuration of the parallel-coupled line (PCL) resonator is used to design the ML band-pass filter. The FR4 substrate with a dielectric constant (εr) of 4.3 and 1.6 mm thickness was used. Comparison analysis between the simulated insertion loss and the reflection coefficient of substrates RO3003 and FR4 was performed to verify the efficiency of the proposed filter design. Simulation of PCL filter is accomplished using computer simulation technology (CST)and an advanced design system(ADS). The PCL bandpass filter was experimentally validated and good agreement between simulation and measured results were achieved showing a well-measured reflection coefficient. The simulated results of the ML bandpass filter show that the circuit performs well, and the filter size is significantly reduced.

Pita frekuensi 5,8 GHz (5725 – 5825 MHz) telah ditetapkan oleh Kementerian Komunikasi dan Informasika Republik Indonesia untuk layanan pita lebar nirkabel. Layanan Wireless Local Area Network (WLAN) juga menggunakan pita frekuensi ini. Sebagaimana layaknya sistem komunikasi nirkabel, perangkat keras pada pita frekuensi ini juga memerlukan tapis lolos rentang (band-pass filter, BPF) untuk memilih frekuensi serta menekan derau dan interferensi. Tugas Akhir ini merancang tapis mikrostrip parallel coupled line dengan tanggapan lolos rentang. Bahan yang digunakan adalah Rogers RO4350B (permitivitas relatif 3,66 pada frekuensi  8-40 GHz dan rugi-rugi dielektrik 0,0037 diukur pada frekuensi 10 GHz). Spesifikasi tapis diturunkan dari analisis terhadap datasheet tapis komersial yaitu lebar pita 100 MHz, nilai insertion loss <1 dB dan return loss ≥11 dB, orde tiga polynomial Chebyshev. Perangkat lunak yang digunakan adalah AWR Design Environment 10 untuk menentukan skematika rangkaian dan nilai komponen, serta simulator elektromagnetik CST Microwave Studio 2014 untuk verifikasi desain. Proses optimasi desain untuk mencapai spesifikasi dibantu dengan Design of Experiment (DOE). Hasil simulasi DOE diperoleh nilai komponen baru yaitu, W dan  masing-masing sebesar 1,61 mm dan 7,23 mm. Dengan nilai komponen baru tersebut diperoleh nilai insertion loss dan return loss masing-masing sebesar 1,51 dB dan 29,32 dB, dan lebar pita sebesar 67 MHz.

Envelope analysis based on the combination of complex Morlet wavelet and Kurtogram have advantages of automatic calculation of the center frequency and bandwidth of required band-pass filter. However, there are some drawbacks in the traditional algorithm, which include that the filter bandwidth is not -3dB bandwidth and the analysis frequency band covered by the filter-banks are inconsistent at different levels. A new algorithm is introduced in this paper. Through it, both optimal center frequency and bandwidth of band-pass filter in the envelop analysis can be obtained adaptively. Meanwhile, it ensures that the filters in the filter-banks are overlapped at the point of -3dB bandwidth and the consistency of frequency band that the filter-banks covered.
