The microstrip array antenna (MSA) is fabricated on inexpensive FR4 substrate and placed 1mm above ground plane to improve the bandwidth and efficiency of the antenna. A reactive impedance surface (RIS) consisting of 13×13 array of 4 mm square patches with inter-element spacing of 1 mm is fabricated on the bottom side of FR4 substrate. RIS reduces the coupling between the ground plane and MSA array and therefore increases the efficiency of antenna. It enhances the bandwidth and gain of the antenna. RIS also helps in reduction of SLL and cross polarization. This MSA array with RIS is place in a Fabry Perot cavity (FPC) resonator to enhance the gain of the antenna. 2×2 and 4×4 array of square parasitic patches are fed by MSA array fabricated on a FR4 superstrate which forms the partially reflecting surface of FPC. The FR4 superstrate layer is supported with help of dielectric rods at the edges with air at about λ0/2 from ground plane. A microstrip feed line network is designed and the printed MSA array is fed by a 50 Ω coaxial probe. The VSWR is <; 2 is obtained over 5.725-6.4 GHz, which covers 5.725-5.875 GHz ISM WLAN frequency band and 5.9-6.4 GHz satellite uplink C band. The antenna gain increases from 12 dB to 15.8 dB as 4×4 square parasitic patches are fabricated on superstrate layer. The gain variation is less than 2 dB over the entire band. The antenna structure provides SLL and cross polarization less than -2ο dB, front to back lobe ratio higher than 20 dB and more than 70 % antenna efficiency. A prototype structure is realized and tested. The measured results satisfy with the simulation results. The antenna can be a suitable candidate for access point, satellite communication, mobile base station antenna and terrestrial communication system.","PeriodicalId":118902,"journal":{"name":"2016 International Conference on Microelectronics, Computing and Communications (MicroCom)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129357734","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}

Preprocessing is the main step in any text processing systems. One significant preprocessing technique is the elimination of functional words, also known as stopwords, which affects the performance of text processing tasks. An efficient stopword removal technique is required in all text processing tasks. In this paper, we are proposing a stopword removal algorithm for Hindi Language which is using the concept of a Deterministic Finite Automata (DFA). A large number of available works on stopword removal techniques are based on dictionary containing stopword lists. Then pattern matching technique is applied and the matched patterns, which is a stopword, is removed from the document. It is a time consuming task as searching process takes a long time. This makes the method inefficient and very expensive. In comparison of that, our algorithm has been tested on 200 documents and achieved 99% accuracy and also time efficient.","PeriodicalId":118902,"journal":{"name":"2016 International Conference on Microelectronics, Computing and Communications (MicroCom)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129485920","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}

Photonic microwave frequency multiplication based on external intensity modulation has been considered as an effective solution for frequency tunable microwave and millimeter wave signal generation. In this paper, we analyze and demonstrate a technique for photonically assisted microwave frequency quadrupling. A theoretical analysis to achieve the microwave frequency quadrupling using two cascaded Mach-Zehnder modulators is presented. By this technique, a four-fold microwave or millimeter wave signal are photonically generated without the need for an electrical or optical filter. The detailed simulations are presented in electrical and optical domain to investigate the performance of the developed technique. We have demonstrated experimentally the implementation of a microwave frequency quadrupler in the frequency range of 24 GHz to 34 GHz. The generated microwave signal has a very narrow linewidth along with the feature of wideband frequency tunability.","PeriodicalId":118902,"journal":{"name":"2016 International Conference on Microelectronics, Computing and Communications (MicroCom)","volume":"61 16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123393152","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}

Multicast routing in mobile Ad-hoc networks (MANETs) have many defiance due to implicit characteristics of the network such as node mobility, reliability, finite network resources etc. So, in this paper we have introduced a new scheme to improve the performance and efficiency of multicast routing protocols. Our proposed scheme is called multicast routing using limited flooding mechanism. This mechanism is integrated over MAODV which enhance the multicast routing efficiency. This mechanism manages the data packets flow based on delay characteristics of the contributing nodes. In proposed scheme only the nodes that satisfy the delay requirement can only flow the data packets from source node to a multicast receivers. The proposed scheme calculates the various types of delay such as transmission delay and propagation delay on each contributing mobile nodes to establish the multicast routes. This scheme is inspired by studied some implicit lacks of existing multicast routing protocols such as: weak robustness of dynamic topology, low reliability, low scalability, lack of QoS (Quality of Service) support, less packet delivery ratio and high packet delivery delay.","PeriodicalId":118902,"journal":{"name":"2016 International Conference on Microelectronics, Computing and Communications (MicroCom)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128147818","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}
