The proposed hybrid phase shifter consists of an analog-type active phase shifter and a digital-type passive phase shifter. To verify the idea the circuit is designed using 0.13-μm RF CMOS technology at 22–26-GHz UWB frequency band. The hybrid phase shifter has the continuous phase shift range up to 25.40, which is able to cover almost two times of the designed analog or digital phase shifter range. The gain drift of about −2.0 dB to 0.7 dB at 24-GHz is observed during phase shift. The simulation results confirm that the proposed hybrid phase shifter can be a good candidate as one of the phase shifter for the implementation in active phased array or multi-antenna beamforming system.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"46 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130782491","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}

Iridium Main Mission Antennas (MMAs) help provide this uninterrupted service. This paper describes the Iridium system and Main Mission Antenna design and provides an update on MMA mission life and continued performance. The novel MMA phased array panels supply the L-band satellite to ground links for the Iridium system. Key aspects of the antennas are discussed including the RF beam performance, patch radiators, T/R modules, and an onboard power system which minimizes DC power consumption and provides on-orbit redundancy. A mission update for the MMAs is presented including ongoing system support and a longevity study that analyzed component operating data to generate antenna failure and lifetime predictions. Continuing support is discussed including use of a flight worthy MMA and test equipment used to simulate on-orbit antenna performance. Updated MMA control software, which provides enhanced satellite operational flexibility and more robust mission performance, is also described.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131896829","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}

Safavi-Naeini","doi":"10.1109/ARRAY.2010.5613243","DOIUrl":"https://doi.org/10.1109/ARRAY.2010.5613243","url":null,"abstract":"Recent telecommunications standards are requiring antenna technologies to evolve towards low-cost, high-integration packages. Furthermore, higher gain and radiation pattern constraints result in the need of steerable, versatile antenna arrays. One of the key requirements is the overall cost, including non-recurring engineering or designs costs should be reasonably low for consumer market applications. Additionally, an increasing number of applications planned in the near- to mid-term require flexible and/or conformal antennas. Previously developed antenna array technologies have found usage primarily in military-based applications, where design and development time, as well as size are of secondary importance to the antenna performance. As such, bulky phased array antennas have been implemented in the past where the constraints have been primarily on the high-performance of the overall system rather than a certain packaging technology or end-user low-cost application. This paper will discuss a new approach towards more compact integration, discussing initial design of a Ku-band, metallic-waveguide fed active/passive array, and the lead-in to a more cost-effective technology for array feeds. Additional discussion will be on the development of the new printed circuit board waveguide (PCB-WG) and applications at Ku-band, as well 18 GHz and 60 GHz with a variety of antenna elements. Versatility of the new technology is illustrated through the comprehensive design of a 36 GHz dielectric resonator array (DRA). Future development of technology is examined towards the end of the paper. Furthermore, this paper will illustrate how additional research goals and motivations in the field of array antennas can be addressed by the new technology. Such issues as packaging of antenna arrays and front end circuitry to increase the overall gain and reduce the noise figure (NF), as well as novel methods for developing front-end active circuitry will become evident from the core technology development. This can lead to minimizing loss throughout the system, decrease cost, and reduce the overall size.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131494930","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}

Skobelev Networks (also known as chessboard networks), typically used in Limited Field Of View (LFOV) applications, present a modular structure composed by N stages feeding linear arrays partitioned into several overlapped sub-arrays. Each network stage is made up of directional couplers whose coupling coefficients are determined through a constrained optimization routine based on deformed polyhedron methods. In this work an alternative optimization is proposed. The new procedure consists in two steps: 1) computation of the Skobelev Network Scattering Matrix, 2) constrained optimization of directional coupler coefficients adopting a Sequential Quadratic Programming (SQP) method. The results obtained employing this new routine show a remarkable reduction in the sub-array radiation pattern sidelobe level (from 4.7 dB for N = 1 up to 6.49 dB for N = 4) with negligible effects on the main beam.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113965930","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 RTPS consists of a differential, vertically-coupled, coupled-line hybrid and variable, parallel-LC, resonant, reflective loads, both of which enable low-loss millimeter-wave operation. The design considerations for a silicon-based implementation of all the beamformer elements are discussed in detail. In particular, the influence of the different RTPS components on its insertion loss is analyzed. The beamformer IC and a breakout of the RTPS are implemented using CMOS-only features of IBM's 8HP 0.13¡jm SiGe BiCMOS process, and employ areas of 2.1mm2 and 0.33mm2, respectively, without probe pads. Differential s-parameter measurements at 60GHz show a phase-shift range greater than 150°, insertion losses of 4–6.2dB in the RTPS and 14–16dB in the beamformer, and an isolation better than 35dB between adjacent beamformer channels. Measurements across temperature and process variations are also presented.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115779889","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 technique enables the practical implementation of such super-resolution algorithm by first forming multiple beams in the analog domain to provide data and degree-of-freedom (DOF) reductions without significant loss of information. Super-resolution is then achieved through the use of matrix processing techniques operating on the digitized beamspace data.
