Inspired by this recent finding, we propose a new near-field probe that uses only one single split ring resonator instead of a periodic arrangement of these resonators. We show through numerical simulations that the new proposed probe lead to significant enhancement in the sensitivity as measured by the change in phase in the reflection coefficient. Experimental tests were conducted to detect the presence of a small aluminum block located behind a layer of ground chicken (lossy medium). Preliminary results show that with our new probe, a phase change in the reflection coefficient of 14 degrees can be achieved for 2 mm thick ground chicken and 6.24 mm aluminum cube at an operation frequency of 1.16 GHz.","PeriodicalId":273435,"journal":{"name":"2009 IEEE MTT-S International Microwave Workshop on Wireless Sensing, Local Positioning, and RFID","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128482076","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}

Classical detection technology covers borescopes and geophones in combination with K-9 units for search and rescue missions in ruins, detritus and cones of debris. An improved and time efficient approach for search of vital signs can be realised with UWB (ultra wide band) radar systems, where a very short wide band pulse is transmitted, or with continuous wave (CW) radar systems for measuring movements like respiration. An improvement of CW with a frequency modulation (FM) leads to FMCW radar systems allowing measuring the distance to targets, i.e. buried people. The search for people carrying electronic RF-devices can be assisted with pulse radar systems. Frequency filters of such devices can be exposed to a radar pulse near the filters' resonance frequency and an echo can be detected enabling the localization of a device and probably of the owner, too.","PeriodicalId":273435,"journal":{"name":"2009 IEEE MTT-S International Microwave Workshop on Wireless Sensing, Local Positioning, and RFID","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134502555","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}

In modern metal cutting machine tools the machining result strongly depends on the motor spindles accuracy. Latest developments on high-speed cutting (hsc) and high-performance cutting (hpc) are leading to substantial increasing temperatures and mechanical elongations of the machine parts, which are resulting in decreasing machining precision. Beside wired sensors on stationary parts, temperature- and displacement-measuring systems on fast rotational dynamic shafts like the spindles rotor are very important, since this is the direct interface between the machine tool and the work piece. Different approaches for laboratory setups are known from literature [1], [2]. In this work, a fully spindle-integrated and tested solution suitable for mass production is presented.","PeriodicalId":273435,"journal":{"name":"2009 IEEE MTT-S International Microwave Workshop on Wireless Sensing, Local Positioning, and RFID","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114830556","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 sensor data of a camera and a RFID FMCW reader system are combined based on a synthetic aperture radar principle. The system enables the localization of tagged goods without the use of any installed infrastructure. We integrate a FMCW RFID reader and a camera system into a handheld device. While the handheld device is moved around, radar measurements as well as images of the surrounding area are taken at a number of locations. Thus, a synthetic aperture is generated and the position of the tags is calculated based on a SAR localization algorithm. Based on the imagery of the camera the user receives an augmented visual impression of where to find the RFID transponders.","PeriodicalId":273435,"journal":{"name":"2009 IEEE MTT-S International Microwave Workshop on Wireless Sensing, Local Positioning, and RFID","volume":"133 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120909407","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}

This is very important for near field communication (NFC) applications to ensure a fast and reliable communication between the active device and the transponder with a minimum of battery power. In this paper a new approach using a nonlinear model for the IC and an analytical description of the coil is presented to design a loop antenna with minimal threshold field strength. For comparison the IC is modeled with both a linear model and a nonlinear model. The optimization results for both cases show clearly the advantage of the procedure with a nonlinear IC model. Afterwards, the design constraints due to the input capacitance of the IC is analyzed.","PeriodicalId":273435,"journal":{"name":"2009 IEEE MTT-S International Microwave Workshop on Wireless Sensing, Local Positioning, and RFID","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125376164","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 consists of a capacitively fed annular ring microstrip antenna, which can be shorted via shorting pins on its edges using pin diodes. Therefore, depending on the state of the pin diodes, the antenna operates in normal patch mode (TM11) or unipolar wire-patch mode. The resonance frequencies of both modes are nearly the same and they have overlapping 10 dB impedance bandwidths. In this design, only a single feed point is needed for both excitations.
