Consistent with the RF System-on-Chip (SoC) concept, co-design strategy for circuits and on-chip antennas is described. A number of design and layout issues, arising from the highly integrated nature of this kind of systems, are discussed. The characterization difficulties related to on-chip antennas radiation properties are also highlighted. Finally, a novel on-wafer test fixture is proposed to measure the gain and radiation pattern of the on-chip antennas in the anechoic chamber.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121462133","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 reflectarray has been designed to produce a focused beam at 30 GHz (uplink) in V polarization and also at 20 GHz (downlink) in H polarization. Two separate feeds are used to illuminate the reflectarray for H (20 GHz) and V polarization (30GHz). The reflectarray element is made of two stacked varying-sized patches, being one dimension adjusted to focus the beam at 20 GHz in H polarization, and the other to focus the 30 GHz beam in V-polarization. A breadboard has been manufactured and tested. The measured radiation patterns show very good agreement with those obtained from the simulations. A 10% bandwidth has been obtained in both frequency bands, with an antenna efficiency of 62% at 30 GHz and 70% at 20 GHz","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116572649","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}

Since PDN supply power to core logic and I/O circuits, such power distribution noise can severely limit the performance of the system [2]. Although the frequency response of PDN's can give sufficient insight into their performance, power supply noise is a transient phenomenon and needs to be characterized in the time domain when considering PDN's coupled with nonlinear drivers [3]. Thus, to accurately predict the electrical performance of these power planes over a large bandwidth, accurate broadband macromodeling of power planes is required.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122792952","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 paper examines the ability of modern numerical electromagnetic modeling to predict the gain of these horns and possibly achieve greater accuracy than with the NRL approach.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121769973","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 design is based on a dipole topology and is intended to operate at the L1 frequency of 1.575 GHz. A conventional λ/2 dipole would be too large at this frequency so miniaturization techniques have been applied. The result is a planar antenna whose dimensions are 32 mm × 24 mm, making it one of the smallest GPS antennas ever reported. It exhibits a good impedance match and positive gain at the desired frequency. Furthermore, the antenna incorporates the option of end-loading for bandwidth enhancement. The chosen material system is Low Temperature Co-fired Ceramic (LTCC). This, along with its small size, makes it suitable for integration with System-on-Package (SoP) designs.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"403 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121810038","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}
