The antenna is designed to work at V-band, specifically in the unlicensed bandwidth around 60GHz.The resonant cavity is obtained by means of a woodpile Electronic Band Gap (EBG) structure made of alumina, and exhibits an omnidirectional radiation pattern on the plane normal to the cylinder axis. Such characteristic is extremely important for on-body application, since it improves the signal coverage of the human surface while reducing the energy lost in off-body radiation.","PeriodicalId":6341,"journal":{"name":"2012 IEEE International Workshop on Antenna Technology (iWAT)","volume":"37 1","pages":"152-155"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77577097","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}

Within the frame of the ESA project Compact Low-Mass Global Antennas, EADS CASA Espacio and the Public University of Navarra are developing a light and compact C-band antenna with dual circular polarization. The design of the antenna is based on flat planar technology, leading to two different lines of work. The first one consists in a low profile patch array while the other is based on Electromagnetic Band Gap (EBG) superstrate technology. Both configurations are studied and traded-off for single band working modes in C-band at 3.7 GHz. They are evaluated in terms of compactness, mass and RF performance. The array layout and beam forming network implementation are detailed, as well as the radiator and EBG superstrate selection.","PeriodicalId":6341,"journal":{"name":"2012 IEEE International Workshop on Antenna Technology (iWAT)","volume":"156 1","pages":"307-310"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79874354","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}

A six-element Fermi antenna array working at 5.8 GHz is optimally designed and integrated with the respiration radar system. Specifically, to easily feed the antenna array as well as reduce the total size of the array system, a feeding network based on 0-degree phase shifters is employed along with suitable impedance transformers. The whole system is proposed to function as a radar sensor for respiration rate measurement, which is known as a promising non-contact and non-invasive approach for lung cancer radiotherapy. The measurement results verify the improved performance of the proposed system for radar respiration measurement in motion-adaptive lung cancer radiotherapy.","PeriodicalId":6341,"journal":{"name":"2012 IEEE International Workshop on Antenna Technology (iWAT)","volume":"99 1","pages":"60-63"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81583608","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}

Metamaterial based winding ring structures are employed to achieve the proposed high performance inductor. Specifically, the proposed structure is realized by utilizing the multiple metal-layers and vias available in a CMOS process. It is found that, by controlling the number of additional metamaterial ring structure applied to the original spiral inductor, the total inductance can be tuned. Using full-wave electromagnetic simulator, 20% and 40% increase are achieved in inductance when adding single-turn and two-turn metamaterial winding rings respectively. Moreover, the resultant Q of the metamaterial based tunable inductor is also increased from 2.75 to 3.75 at 17GHz (i.e. 36% increment).","PeriodicalId":6341,"journal":{"name":"2012 IEEE International Workshop on Antenna Technology (iWAT)","volume":"51 1","pages":"233-236"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87604397","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 simulation results from the CST software illustrate that the antenna's half-power beamwidth exceeds 110? and the phase center variation is within 1mm at different elevations ranged from -55° to +55° over 20MHz bandwidth, which demonstrate that the proposed antenna design is quite applicable for satellite navigation system.","PeriodicalId":6341,"journal":{"name":"2012 IEEE International Workshop on Antenna Technology (iWAT)","volume":"66 1","pages":"96-99"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87995264","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}

Rather than introducing an external matching network that requires both resistance and reactance matching, our systems rely on internal non-Foster elements that are designed to vary the performance of their near-field resonant parasitic (NFRP) elements. Hence, by augmenting their narrow bandwidth counter-parts with internal non-Foster elements, the resulting electrically small antennas remain nearly completely matched to a 50 Ω source without any matching network and exhibit high radiation efficiencies over their FBW10dB bandwidths. These instantaneous bandwidths are nearly two orders of magnitude larger than those provided by their passive counterparts.","PeriodicalId":6341,"journal":{"name":"2012 IEEE International Workshop on Antenna Technology (iWAT)","volume":"20 1","pages":"293-296"},"PeriodicalIF":0.0,"publicationDate":"2012-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83438382","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}
