The RF EH is composed of five matching networks realized on a low-loss integrated-passive-devices (IPD) carrier and five rectifiers on a 0.18-μm CMOS chip. The CMOS chip is flipped and bonded to the IPD carrier through low-loss interconnects so that each on-chip rectifier can be integrated with an on-carrier matching network to support one of five band operations. High-g IPD passive components are employed to realize the matching networks. This not only provides a compact and low-cost solution, but the matching network can also give a high voltage gain to enhance the EH dc-to-RF conversion efficiency η. Native devices with a low threshold voltage provided by the 0.18-μm CMOS technology are chosen to improve the rectifier sensitivity. The proposed RF EH can give measured output voltages of 1.75, 1.77, 1.23, 1.19, and 1.26 V with n of 15.4, 15.7, 7.6, 7.1, and 8.0% at 0.74, 0.89, 1.8, 2.12, and 2.36 GHz, respectively, as the input RF power is −14 dBm and the load resistance is 500 kΩ. The proposed RF EH only occupies a 16.56 mm2 area.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"98 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":"125281762","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 prehension on the complex permittivity of the hydrated soil became integral technology, so that the complex permittivity was measured as the function of the water volume content at frequency bands from low frequency (LF) to medium frequency (MF), and the transmission and reflection characteristics of the hydrated soil was calculated based on the propagation model applying the measured complex permittivities. From the result, it is obvious that the reflection from the hydrated soil behaves as a key role to estimate the water content. In addition, the complex permittivities of live and dead leaves, woods and stones were measured and the reflection characteristics of the forest existing on the surface of the land were calculated and evaluated. It is found from the calculated results that their influence is little for the reflection characteristics. Finally, the initial consideration of the landslide prognostication system using the bistatic radar technology was performed.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"1 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":"126218271","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}
