Satellite communication has made a major contribution to the pattern of international communications, whetherin geostationary Earth orbit (GEO) or non-GEO. The engineering aspect of satellite communications combinessuch diverse topics as antennas, radio wave propagation, signal processing, data communication, modulation,detection, coding, filtering, orbital mechanics, and electronics. To satisfy the future traffic increase, the Kafrequency band from 17.5 to 21.2 GHz is designed to provide a high service availability with much higher datarates. This proposal addresses a subject of current interest for ORBITAL RESARCH Ltd., a successful,privately owned manufacturer and distributor of Custom BDCs (Block Down Converters), LNBs (Low NoiseBlock down converters) and System Interface Products for satellite communications. Through the ENGAGEprogram a research team from INRS-EMT in collaboration with the R&D department of the industrial partnerORBITAL RESARCH will design and characterize new microwave circuits to improve the efficiency of theLNB (Low Noise Block-downconverter) for satellite communications. Important issues related to bandwidthtunability, noise, center-frequency tunability, and selectivity must be achieved over the Ka-band. SubstrateIntegrated Waveguide (SIW) technology presents an excellent trade-off between high-Q, compactness, easyintegration with other planar circuits and low-cost fabrication process. In this context, a tunable SIW bandpassfilter over the whole Ka-band will be the heart of the project. The proposed project will be highly costeffective because of the available facilities at INRS-EMT RF laboratory, where a critical mass of infrastructureand resources can be exploited for its success. The objectives of the proposed research are (i) to design,develop, and characterize microwave circuits (mainly filters), adapted to the specific needs of the industrialpartner, and (ii) training of highly qualified personnel to respond to the scientific and technologic challenges ofour society.

无论是地球静止轨道还是非地球静止轨道，卫星通信都对国际通信格局作出了重大贡献。卫星通信的工程方面结合了诸如天线、无线电波传播、信号处理、数据通信、调制、检测、编码、滤波、轨道力学和电子学等不同的主题。为了满足未来业务量的增长，从17.5 GHz到21.2 GHz的kaffrequency频带被设计为具有更高数据量的高业务可用性。该提案解决了ORBITAL research有限公司当前感兴趣的主题，该公司是一家成功的私营制造商和分销商，为卫星通信提供定制bdc（块下变频器），lnb（低噪声块下变频器）和系统接口产品。通过engage项目，来自INRS-EMT的一个研究小组将与工业合作伙伴orbital research的研发部门合作，设计和表征新的微波电路，以提高用于卫星通信的nb（低噪声块降频器）的效率。与带宽可调性、噪声、中心频率可调性和选择性相关的重要问题必须在ka波段上实现。亚策略集成波导（SIW）技术在高q、紧凑、易于与其他平面电路集成和低成本制造工艺之间取得了很好的平衡。在这种情况下，整个ka波段的可调谐SIW带通滤波器将是该项目的核心。拟议的项目将具有很高的成本效益，因为INRS-EMT射频实验室拥有可用的设施，在那里可以利用大量的基础设施和资源来取得成功。拟议研究的目标是(i)设计、开发和表征微波电路（主要是滤波器），以适应工业合作伙伴的特定需求，以及（ii）培训高素质人才，以应对我们社会的科学和技术挑战。
