Modern data communication, such as wireless technology with IEEE 802.11 b/g/n standard, demands its antenna to have ability to conform to the changing environment. In this paper, such antenna with the ability of radiation pattern reconfiguration is proposed. The antenna which is configured in a planar array is designed on 2 layers of FR4 epoxy dielectric substrate. On top side of the first layer, 8 square patch antennas workable at the frequency of 2.4 GHz are circularly configured and fed using a microstrip feeding line based on proximity coupling technique. The microstrip feeding line is printed on top side of the second layer, while the groundplane which takes a circular shape is placed on bottom side of the second layer. PIN diodes with the type of SMP1345-079LF are connected at the end of microstrip feeding lines to modify the radiation pattern of array antenna. When 2 antennas positioned across each other are set to be active, the measured reflection coefficient is –14.39 dB at frequency of 2.4 GHz. In addition, the antenna has and the measured gain of 0.25 dBi and –10 dB working bandwidth of 240 MHz ranges from the frequency of 2.32 GHz to 2.56 GHz.

This paper deals with the performance analysis of bandpass filter (BPF) composed of substrate integrated waveguide (SIW) and the influence of number of complimentary split ring resonators (CSRRs) incorporated into the filter. The performance analysis is emphasized on how the number of CSRRs incorporation affects to the parameters of filter, namely bandwidth, insertion loss, and return loss. The analysis is applied for the BPF without CSRRs as well as with the number of CSRRs incorporation. The SIW BPF is designed on an FR4 epoxy dielectric substrate with the thickness of 1.6mm and the relative permittivity of 4.3. Meanwhile, each CSRR comprises of 2 concentric rings with the ring width of 2mm and the diameter of 12mm and 7mm for the outer and inner ring, respectively. From the analysis, it shows that the number of CSRRs incorporation into SIW BPF contributes to the number of frequency bands in the passband area. However, the bandwidth of additional band is narrow for the increase number of CSRRs incorporation.

Student assignments is one component that influences the final score of a course given by the lecturer. The assignment of a course is charged at 20% of the final assessment of a course. Each lecturer has an average of 40 students in each class, while the lecturer can teach more than one class of courses. The large number of students will make the number of assignments too large because the ratio of the number of lecturers and students is very different. This is a burden on the lecturer because it has the responsibility to check each of student work assignments. The level of similarity of course assignments is one of the ways lecturers can assess a subject's assignment. This study aims to help lecturers detect the similarity of student tasks by using a task similarity detection system. This study uses Rocchio method to detect the similarity of words. The type of document tested is formatted in .pdf. The language used in the course is Indonesian. The preprocessing stages in this research consists of Case Folding, Tokenizing, Filtering, Sorting. The TF.IDF uses as the word weighting and the similarity measurement with the Rocchio method so that it gets the percentage value of the similarity between documents. The development stage started from planning, analysis, design, implementation and testing. The testing stage including testing with dummy data and usability data. Based on the research that has been done, the Rocchio method can classify documents that are similar to the results of the accuracy of 74,6% and detection errors from the similarity of queries with documents of 2.54 or 25.4%.

We consider the sum rate of massive multiple input multiple output (MIMO) systems where the base station (BS) antenna configuration is uniform circular planar array (UCPA). The channel considered is line-of-sight (LOS) governed by the antenna steering vector of each user. The user azimuth and elevation angles are assumed independent and uniformly distributed. The BS performs maximum ratio transmission (MRT) beamforming due to its low complexity and acceptable performance for low to moderate signal-to-noise ratio (SNR). The sum rate performance is then analyzed and compared to the upper bound sum rate obtained by assuming favorable propagation in massive MIMO. It is shown that using a larger amount of antennas increases the slope of the sum rate curve.

Performance of microstrip circular patch antenna is determinable from the dielectric substrate used between the patch and the groundplane. An FR4 epoxy dielectric substrate is one of the materials which is frequently used to implement the microstrip patch antenna. This paper presents a performance analysis of microstrip circular patch antenna composed of artificial dielectric material (ADM). Here, the ADM is made of an FR4 epoxy dielectric substrate as the host material which is modified by incorporating a number of thin conductor wires into inside of the dielectric substrate. Meanwhile, a conventional microstrip circular patch antenna is also designed as comparison by using the same dielectric substrate without any modification. The characterization results show that the resonant frequency of microstrip circular patch antennas made of ADM with 82 and 110 thin conductor wires are 16.19% and 23.17% lower than of the conventional microstrip circular patch antenna, respectively. Whilst the–10dB working bandwidths of microstrip circular patch antenna made of ADM with 82 and 110 thin conductor wires are around 72.9MHz narrower around 43.4% than of the conventional microstrip circular patch antenna. In addition, the gains of microstrip circular patch antenna made of ADM with 82 and 110 thin conductor wires are 5.54dBi and 6.1dBi, respectively, where these are relatively higher than of the conventional microstrip circular patch antenna which has the gain of 5.24dBi.

Whilst the–10dB working bandwidths of microstrip circular patch antenna made of ADM with 82 and 110 thin conductor wires are around 72.9MHz narrower around 43.4% than of the conventional microstrip circular patch antenna. In addition, the gains of microstrip circular patch antenna made of ADM with 82 and 110 thin conductor wires are 5.54dBi and 6.1dBi, respectively, where these are relatively higher than of the conventional microstrip circular patch antenna which has the gain of 5.24dBi.","PeriodicalId":159795,"journal":{"name":"2018 12th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"228 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124501741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
