Millimeter-wave models for both passive and active components are developed based on the standard foundry provided models with extra critical variation components which represent modeling uncertainties. The proposed model is verified through a comparison with the measured results of the test structures. The design methodology of tolerating the modeling uncertainties is demonstrated by a design example of a 65nm CMOS 57–64 GHz low noise amplifier, which has a 20 dB gain and a minimum 5 dB noise figure with 26 mA current consumption under 1 V supply.","PeriodicalId":253374,"journal":{"name":"WAMICON 2011 Conference Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129516724","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}

Macro and micro base stations have traditionally been used to provide coverage and capacity, respectively. In this paper, we analyze a new approach in which coverage is provided by means of inband relays. We show that compared with a traditional network based on macro base stations, a good outdoor coverage for a target data rate could be provided in a more cost efficient way by deploying a network based on pico base stations and relays. However, this is valid only for low data-rate because part of the spectrum is allocated to the backhaul and therefore the capacity of cellular-relaying networks is typically limited. Moreover, this break-even point depends on how the networks are deployed.","PeriodicalId":253374,"journal":{"name":"WAMICON 2011 Conference Proceedings","volume":"412 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115239053","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}

At both input and output matching networks, we add parallel resonators between series microstrip lines and open-circuited stubs to realize the dual-band operation. With our proposed structure, we can use the conventional L-type structure to design matching network for each operation frequency so that the design is easier. By using just one transistor without any tunable electronic element or switch, a novel dual-band class AB power amplifier working at 1.5 GHz and 2.4 GHz is designed and fabricated to demonstrate our proposed simple method. With dual-band matching networks using resonators, the experimental results show the output power 40.3 dBm and 39.05 dBm with power added efficiency (PAE) 55.63% and 40.25% at 1.5 GHz and 2.4 GHz, respectively.","PeriodicalId":253374,"journal":{"name":"WAMICON 2011 Conference Proceedings","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127447938","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}

Moreover, for performing heating and radiometry inside the tissues, the specific absorption rate (SAR) profile generated in the near-field of the antennas is the quantity of interest rather than the radiation pattern. On the other hand, for medical implants, the SAR profile and the tissue loss are undesired effects, but are unavoidable and greatly impact the radiation property and the gain of the antennas. This paper highlights some of these mentioned issues. It presents planar antennas utilized for an intracranial pressure monitoring (ICP) implant and radiometer/heating antennas applied for the measurement of blood perfusion. Measurement setups and/or procedures for the characterization of the antennas will be discussed as well.","PeriodicalId":253374,"journal":{"name":"WAMICON 2011 Conference Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130714566","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 sensors are intended for deeply embedded structural health monitoring applications. As such, the interrogator must both transmit a signal to elicit a response from the sensor and be able to monitor that response. The interrogator considered transmits in the 2.40–2.48 GHz ISM band and monitors the 2nd harmonic response created by the sensor. The interrogator employs two fractional-N PLLs, one for frequency synthesis of the interrogating signal and one for a reference at a fixed frequency offset. The received signal lies in the 4.80–4.96 GHz band and is downconverted to a constant frequency (70 MHz). The output frequency of the two PLLs is controlled by a single FPGA. The interrogator is designed to either sweep across the transmit band or to transmit at a fixed frequency within the band depending on whether the sensed parameter is static or dynamic, respectively, in nature.","PeriodicalId":253374,"journal":{"name":"WAMICON 2011 Conference Proceedings","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124406127","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}

Specifically, a sensor relocation method is introduced, based on a multi-objective genetic algorithm. The algorithm objectives are the total travel distance of the sensors from their initial locations to their final locations as well as the coverage area of the sensors. Simulation results clearly show the tradeoff between the travelled distance and coverage area. This algorithm can be used to achieve best coverage, and our results demonstrate that a better coverage always needs a larger travelled distance. Furthermore, redundant sensors decrease the travelled distance. The travelled distance also depends on the initial position of the sensors. The proposed algorithm also works when obstacles appear in the sensing field.","PeriodicalId":253374,"journal":{"name":"WAMICON 2011 Conference Proceedings","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114684055","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 technique is based on a high quality (Q) factor resonator method, which allows accurate characterization of both dielectric constant and loss tangent. SiCN ceramic materials are measured from 50°C up to 500°C. It is observed that the dielectric constant of SiCN increases from 3.71 to 3.87, corresponding to a temperature range between 50 and 500°C.
