Preservation of wildlife has taken the center stage today. Tigers and lions are poached for their teeth and fur which may lead to their extinction. In the last few years tiger poaching has increased dramatically fueled by illegal trade of tiger body parts. In order to safeguard our animals from the dangers of poaching, this paper proposes an electronic device constructed using Global Positioning System (GPS), Global System for Mobile Communications (GSM) interfaced with a heart rate sensor. The sensor takes the heart rate of the animal as input and subject to certain conditions in code alerts the concerned authority facilitating required action.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133112615","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 antenna radiation pattern can be changed by changing the state of the diodes loaded in the phase varying reflector. A planar dipole antenna is used to excite the tunable reflector. By this technique the antenna beam can be steered from +300 to -300 in the broadside direction depending on the operating state of the diodes. Moreover, the state of the diodes can be addressed digitally and hence a steep gradient in phase can be achieved in the reflector. The antenna radiation pattern and the gain has been found stable all over its states.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"27 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131062240","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}

Circular polarization is procured by exciting orthogonal mode in half-split CDR through modified CPW-feed. TM11Ô mode is excited inside the HS-CDRA and confirmed by the rotation of electric field.
