Prior to the designs, the solver has been validated through comparisons of its computed results with the ones which came from some analyzed structures previously published in other literature, and a good agreement has been observed. The results synthesized by the proposed designs lead to a strong belief that the FDTD is indeed a robust, versatile and powerful algorithm in solving various electromagnetic problems.","PeriodicalId":416991,"journal":{"name":"Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2000]","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133865445","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}

Spurious moding problems of the previous design approaches are studied and a new mode-suppressing scheme is proposed and used in this filter design. The filter performance is effectively improved, especially for the upside stop-band rejection. It is shown that both the hybrid planar/NRD transition and the developed mode suppressor are able to reduce all the spurious modes to a required level. This design technique provides a useful solution to higher performance planar NRD-guide filter at millimeter-wave frequency.","PeriodicalId":416991,"journal":{"name":"Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2000]","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129447500","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, the development and the spreading of NF-FF transformation techniques employing planar, cylindrical or spherical scanning systems is justified from the fact that each approach has its own particular advantages and limitations. In this context, as suggested in [1], [2], a continuous movement of the positioning systems of the probe and of the antenna under test (AUT) permits to reduce complexity and cost of the measurement set-up, as well as the time needed for data acquisition. In particular, with reference to the innovative (uniform) helicoidal scanning proposed in [2], a nonredundant sampling representation of the electromagnetic field over a circular helix with constant step in z has been developed. The corresponding interpolation algorithm has resulted to be fast, accurate and stable, so that it can be employed to reconstruct the field over the considered cylinder in the NF region at any point required by the cylindrical NF-FF transformation techniques available in literature.","PeriodicalId":416991,"journal":{"name":"Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2000]","volume":"203 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128689364","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}

High speed circuits require an accurate prediction of transmission-line effects such as ringing, reflection, distortion, and crosstalk. Typically, interconnections on integrated circuits, printed circuit boards, and multichip modules are modeled with large linear networks, which may consist of hundreds and thousands of lumped and distributed components.

Impedance matching at each interstage harmonic frequency is performed directly between transistors by means of a single transmission line. This multiplier translates a low-GHz input signal (∼ 0 dBm), with a conversion gain, into an output as a local oscillator, resulting in eliminated drive amplifiers. The validity of this topology is demonstrated by two, and three-stage multipliers to 14.25 GHz and 28.5 GHz, respectively, developed using medium power (H)FETs.","PeriodicalId":416991,"journal":{"name":"Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2000]","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127671343","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}
