Very low insertion loss is beneficial in view of low receiver noise and good radiometric resolution (NEDT). Very low insertion loss can be achieved with ferrite junction switches. In developing millimeter wave ferrite junction switches, however, the small dimensions of the ferrite becomes a challenge. Targeting towards W band (89 GHz), two frequency-scaled switches at Ka band (36.5 GHz) have been developed in the current work. One of the switches applies higher order mode operation, resulting in larger ferrite dimensions. A reference switch to apply dominant mode operation has been developed as well. In this study, the feasibility of both dominant mode and higher order mode operation switches has been confirmed and good compliance between simulations and measurements observed. The switches have average insertion losses of 0.85 dB and 0.3 dB over 1.0 GHz and 4.5 GHz, respectively.","PeriodicalId":156809,"journal":{"name":"2016 Global Symposium on Millimeter Waves (GSMM) & ESA Workshop on Millimetre-Wave Technology and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130801139","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}

In this paper, a novel mm-Wave 256 element phased array system based on 8 element sub-arrays is presented. The sub-arrays are randomly tiled so the periodicity in the array is disrupted and significantly reduce the side lobe level (SLL). Four different rectangular sub-arrays: 1×8, 8×1, 2×4 and 4×2 are used to completely fill the phased array aperture. The steering range is ±15° in both Azimuth and Elevation planes achieving <; -10dBc grating lobe/SLL and better than 60% aperture efficiency. This technique greatly reduces the required array control circuits in a large-scale array. It can be a great candidate for multi-Giga-bit/s (Gbps) 5G communications and it can be realized with multilayer technologies such as low temperature co-fired ceramic (LTCC).","PeriodicalId":156809,"journal":{"name":"2016 Global Symposium on Millimeter Waves (GSMM) & ESA Workshop on Millimetre-Wave Technology and Applications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129038330","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 is devoted to a brief overview of the new and alternative to known approaches to the development of mesoscale systems for localization and transport of electromagnetic fields to the subwavelength region. Our approach is based on mesoscale dielectric particles of arbitrary three-dimensional shape. Its aim is to replace information channels with metallic structural components to the photonic ones, based on materials with small positive value of dielectric constant, and the air gaps. Proposed compressed system can improve the spatial resolution of electromagnetic beams in the millimeter wave or THz bands.","PeriodicalId":156809,"journal":{"name":"2016 Global Symposium on Millimeter Waves (GSMM) & ESA Workshop on Millimetre-Wave Technology and Applications","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115232430","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}
