With a 60 MHz bandwidth, the −3 dB cutoff signal at a frequency of 486 MHz for the tape top side, as well as for the 426 MHz frequency band lower side. To produce the steepness of the above −30 dB and ripple 0.1 dB the pass-band region, the filter design using a seven pole with family order Butterworth filter used. To lower the cutoff frequency, stopband width (Fs) is designed about 20% at a frequency of 340.8 MHz, with stop-band depth (As) of about −40 dB. As for the upper cutoff frequency, stopband width (Fs) designed about 20% at a frequency of 583.2 MHz, with stopband depth (As) of about −40 dB. Using the components of surface mount technology (SMT), then generated band-pass filter module with small dimensions, compact and has a high Q.

Many scientific, industrial and environmental applications require real time information related to physical events like pressure, temperature or humidity. In the past the only way to transfer the sensed data to control center was through cumbersome, costly wires. But recent advancement in wireless networking enables WSNs to communicate the sensed real time event data wirelessly. WSNs have capabilities of sensing, processing and communicating which make them most suitable for monitoring different oil and gas industries upstream, midstream and downstream operations which help to increase production, decrease the accidents, maintenance cost and malfunctioning. The contributions of this paper are threefold. First, we highlight various characteristics of both WSNs and Oil and Gas Industrial environment. Second, we present major requirements of Oil and Gas industrial operations in the three sectors upstream, midstream and downstream. Third, we present the important issues and challenges specific to Oil and Gas industrial environment which affects the working and efficacy of WSNs. These issues and challenges should be considered by the researchers and developers who are planning to design a WSNs based solution for Oil and Gas monitoring.","PeriodicalId":132981,"journal":{"name":"2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127874159","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}

The radar has two separate and parallel antennas: transmit and receive antennas. Low SLL will introduce high antenna isolation. For achieving a good performance, the required SLL is set to a minimum of 13 dB to produce high isolation and maximum reflection (echo) on the antenna main lobe. The Chebyshev method was applied for improving the main lobe efficiency, which is by modifying incoming power distribution on each patch. The patch shape was rectangular and this shape is modified by inserting slots to change polarization direction from vertical to horizontal polarization. Antenna feeding is performed by using the proximity method that aims to reduce radiation effect from transmission lines. This results in low interference to the main antenna radiation. The SLL for Chebyshev method is about −30dB and, for Uniform distribution, the SLL is about −13dB. The antenna development was started from defining its configuration, design and simulation, and finalized by optimization. From the simulation results, Chebyshev method gives low SLL and higher isolation in comparison to that of uniform method. For the Chebyshev antenna array with a distance of 9cm, the value of S12 equals −77.18048 dB and S21 equals −77.18053 dB. While for uniform antenna array with 13cm air gap, the S12 equals 75.864015 dB and S21 equals −75.86401dB. Lower values of S12 and S21 show higher antenna isolation. From the experiments, it was shown that the air gap distance is not linearly related to the isolation level. There is a certain distance where the optimum isolation value can be achieved. For the Chebyshev antenna array, it was shown that the simulation and measurement results are very similar.","PeriodicalId":132981,"journal":{"name":"2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126351695","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}

The radio over fiber technique is useful for precise signal generation and distribution over the fiber network. In the scenario, each millimeter-wave radar head is not necessary to be equipped with a precision radar signal source; low cost and low energy consumption radar head will be realized. For connection to the optical network, advanced high-speed optical/electrical converters are developed for signal conversion from/to optical signals in 90-GHz band directly in a central office and each radar head. A signal-to-noise power ratio of generated 90-GHz optical signal was achieved larger than 30 dB: enough quality to use in the radar system. An optical switching technique is useful not only for routing the optical signal to the radar heads but also for filtering unnecessary optical components. These device technologies are applicable for distributed millimeter-wave radar systems.","PeriodicalId":132981,"journal":{"name":"2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117354846","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}

Ambient vibration energy can be utilised by electromagnetic, electrostatic and piezoelectric mechanisms to provide electrical energy. Piezoelectric mechanism is widely preferred due its effective piezoelectric effect. Resonant frequency of structure is a vital parameter in piezoelectric energy harvesting. In this paper, proof mass effect on piezoelectric cantilever beams was analysed to reduce resonant frequency. The structure of the beams were designed in SolidWorks. The beams were consisted of bi-layered PZT-5H, Aluminium substrate and Tungsten proof mass. The dimensions of proof mass were varied only. The other parts were remain unchanged in dimensions. The beams were analysed by using Finite Element Method (FEM) in COMSOL Multiphysics. Vibration acceleration of 1 g (g = 9.81 m/s2) was applied on both beams. Higher terminal voltage of 7.8 mV was obtained at lower resonant frequency of 163.4 Hz from the beam with larger proof mass. While from the other beam with smaller proof mass, terminal voltage of 7.64 mV was obtained at higher resonant frequency of 190.3 Hz. The designed and analysed beams can be used for wireless sensor networks, monitoring structures, temperature and humidity sensors etc.","PeriodicalId":132981,"journal":{"name":"2016 International Conference on Radar, Antenna, Microwave, Electronics, and Telecommunications (ICRAMET)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122121004","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}
