The antenna design has to fulfill the requirements of the IBM CMOS process and the MEMS post CMOS processing. The antenna is coupled directly to the sensor, a MOSFET bolometer. Because of this direct coupling and the need for real time imaging, only extremely physically small antennas are feasible. Hence, typical broadband antennas like the toothed log-periodic antenna are not useable for this application and new antenna approaches have to be examined.","PeriodicalId":247542,"journal":{"name":"2013 International Workshop on Antenna Technology (iWAT)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115192728","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 size of the gain is affected greatly by how the T-CNP antenna is illuminated with the incident plane wave. The gain of the T-CNP antenna with its axis along the direction of the incident E-field is 27.5 dB, while it is only 1.0 dB when the axis of the T-CNP antenna is parallel to the incident wave vector. With the T-CNP antenna's axis parallel to the incident E-field, the antenna responds in a resonant dipole mode.","PeriodicalId":247542,"journal":{"name":"2013 International Workshop on Antenna Technology (iWAT)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131980940","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}

MB OFDM UWB technology has the potential of replacing other wireless technologies within the Personal Area Networks (PANs). Currently MB OFDMUWB devices operate below the expected performance which is largely due to its EIRP limit and frequency selective fading. This bottle neck can be reduced by implementing adaptive modulation in the system. In this Paper, channel measurement of different scenarios has been carried out. The scenarios are model of realistic environment where UWB devices will operate. Effects of different number of human subjects in various movement patterns are studied. The result show implementing exhibit that implementing adaptive modulation in UWB system enhances the performance of the system.","PeriodicalId":247542,"journal":{"name":"2013 International Workshop on Antenna Technology (iWAT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115318658","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}
