Abstract

UWB (Ultra Wideband) adalah sistem komunikasi jarak pendek yang mempunyai bandwidth yang sangat lebar beroperasi pada frekuensi 3,1-10,6 GHz. Dengan bandwidth operasi UWB yang besar maka diperlukan suatu antena dengan bandwidth yang besar pula, salah satu pendekatan untuk memperlebar bandwidth antena adalah dengan menggunakan Theory Characteristic Mode (TCM). Perancangan antena monopol cetak pada frekuensi kerja 3,1-10,6 GHz menggunakan bahan FR-4 dengan ketebalan 1,575 mm, dan konstanta dielektrik sebesar 4,3. Simulasi pancaran gelombang elektromagnetik menggunakan perangkat lunak CST Studio Suite 2016.  Dari hasil simulasi, antena monopol cetak mempunyai bandwidth 8,4 GHz dengan rentang frekuensi 2,5 – 10,9 GHz. Pada hasil simulasi frekuensi 3,1 GHz, 5 GHz, dan 10,6 GHz yang diperoleh nilai return loss kurang dari -10 dan VSWR sudah kurang dari 2, serta nilai gain lebih dari 2 dB dengan pola radisi omnidirectional. Hasil pengukuran antena monopol cetak mempunyai bandwidth 7,735 GHz dengan rentang frekuensi 3,18-10,915 GHz. Pada hasil pengukuran frekuensi 3,1 GHz, 5 GHz, dan 10,6 GHz yang diperoleh nilai return loss kurang dari -10 dan VSWR sudah kurang dari 2, serta nilai gain sebesar 3,27  dB dengan pola radisi omnidirectional. Antena tersebut telah memenuhi spesifikasi komunikasi ultra wideband.

Abstract

Terdapat banyak metode yang digunakan untuk mengenali identitas seseorang, misalkan nomor unik, kartu identitas dan sandi rahasia. Kekurangan metode-metode tersebut antara lain, kartu dapat hilang, nomor unik dan sandi rahasia dapat terlupakan. Salah satu solusi untuk masalah ini adalah sistem identifikasi seseorang berdasarkan metode biometrik jenis fisiologis. Penelitian ini merancang sebuah sistem untuk mengidentifikasi wajah. Citra wajah diambil menggunakan kamera web kemudian diekstraksi cirinya dengan metode local binary pattern (LBP). Ciri wajah yang diperoleh diklasifikasi menggunakan support vector machine (SVM). Model terbaik SVM dibangun berdasarkan validasi silang grid search. Kernel linier terbaik dibentuk dengan   dan parameter . Kernel radial basis function (RBF) terbaik dicapai dengan   dan parameter  dan .  Berdasarkan pengujian terhadap keseluruhan citra wajah, akurasi kedua kernel adalah 96,0%. Pada pengujian lima ekspresi wajah dengan SVM kernel linier, akurasi 100,0% diperoleh untuk ekspresi sedih, netral dan mata tertutup. Sedangkan SVM kernel RBF menghasilkan akurasi 100,0% untuk ekspresi terkejut, netral dan mata tertutup. Hasil pengujian tersebut menunjukkan sistem pengenalan wajah yang dirancang telah berfungsi baik.

Abstract

Tujuan artikel ini adalah menjelaskan perang gender yang tercermin dalam novel karya pengarang- pengarang perempuan Indonesia dari generasi Ayu Utami. Perang gender adalah ?dendam abadi? pengarang-pengarang perempuan terhadap pengarang laki-laki yang, sampai sekarang, mengeksploitasi tubuh perempuan dengan besar-besaran dan memaksa mereka untuk membaca tubuhnya sendiri dari sudut pandang laki-laki. Melalui teks erotis sebagai bahasa ekspresi, pengarang perempuan mampu menulis tubuh mereka dengan sudut pandangnya sendiri. Abstract: This paper has the objective of explaining the gender struggle implied in the novels of Indonesian female authors of Ayu Utami generation. The gender struggle is female author?s ?eternal enmity? towards male authors who, up till now, have greatly exploited woman?s body and force them to read their own body from the male point of view. Through erotic texts as the language of expression, female authors are able to write their body with their own point of view. Keywords: gender struggle, female authors, Ayu Utami generation

Abstract

This paper presents the analyzed Monopole Antenna for Ultrawideband with a rectangular patch design using bevel technique at a frequency of 3.1 – 10.6 GHz. The fabricated antennas with dual bevel angles have a very compact width and length of 40 mm x 33 mm respectively and a groundplane width of 13 mm. To get bandwidth improvement on monopole antennas can be applied to the bevel angle on the patch. So, to get the best antenna design, 3 optimizations of antenna size changes were carried out during the simulation, that is optimization of patch length, patch width and bevel angle. Variation of patch length and width is used to change the frequency range and variation of bevel angle to increase bandwidth. From each change, the best result is taken. The experiment obtained the best simulation result of antenna and then fabricate it. From the measurement results on the fabricated antenna, the lowest S11 value is -24.6 dB, gain 2.6 dBi at a frequency of 5 GHz and radiation pattern is omnidirectional. The optimization process using the bevel technique has been proven to be successful in shifting the frequency range by around 600 MHz and increasing the bandwidth by about 4% or 30 MHz.

Abstract

The requirement of wireless access networks and user equipments to support coexistence of many communication standards and frequency bands poses challenge on antenna to be broadband and small. The application of half-cut technique to broadband printed monopole with microstrip feeding worsens the resulted antenna’s impedance. To improve the half-cut antenna impedance mathing, two methods were investigated in this paper: (1) monopole and ground extension, (2) the application of microstrip line transformer and ground extension. The first approach only produces limited improvement, whereas method #2 can enhance the return loss significantly. The application of the second approach potentially produces antenna pair that has low mutual coupling, good return loss, and small size. Considering its radiation pattern, the antenna is suitable for diversity and MIMO. Its application in broadband microwave-photonic access point need special arrangement due to radiation null at 5 GHz band at right side.DOI:http://dx.doi.org/10.11591/ijece.v3i5.3376

Abstract

The recent progress of dimension scaling of electronic device into nano scale has motivated the invention of alternative materials and structures. One new device that shows great potential to prolong the scaling is junctionless FET (JLFET). In contrast to conventional MOSFETs, JLFET does not require steep junction for source and drain. The device processing directly influence the performance, therefore it is crucial to understand the role of gate processing in JLFET. This paper investigates the influence of gate material and process on subthreshold performance of junctionless FET, by comparing four sets of gate properties and process techniques. The result shows that in terms of subthreshold slope, JLFET approaches near ideal value of 60 mV/decade, which is superior than the SOI FET for similar doping rate. On the other hand, the threshold value shows different tendencies between those types of device.

Abstract

Non-planar structures have been identified as promising structure for next device generation in the nanoelectronic era. However, the continuous device dimension scaling into nano regime eventually requires more sophisticated model due to the limitation of the existing models. A model for non-planar MOSFET structure was elaborated in this paper, especially for device with pillar structure, using analytical approach. The concern of channel shape and structure were discussed as well. The result shows the shift in subthreshold characteristic in the channel with recessed channel model. The charge sharing is suspected as one of the key parameter in the shift of performance in the recessed region.

Abstract

Radio-over-fiber (RoF) technologies address wireless communication’s need for high data rate, protocol- transparency, and flexibility. One of challenge in RoF access point design is RF amplifier requirement that match to microwave-photonic link chosen and service range needed. This paper proposes a graphical approach as systematic method to solve the challenge. The method identifies two regions, i.e. (a) scalable region where amplifiers’ output 1-dB compression point (OP1dB) improvement can enhance system’s maximum input and output power, and (b) saturation region where any improvement on amplifiers’ OP1dB cannot improve AP’s maximum input and output power. The methods have been verified by system simulations. The errors at scalable and saturation regions are less than 1 dB and the standard deviation is no more than 0.6 dB. The error values around the breakpoint between scalable and saturation regions are around 1 dB. Therefore, the proposed graphical approach can be used in the specification tradeoff between RoF access point input and output power, amplifier’s gain and OP1dB.
