Highly integrated broadband antenna array receiver for wireless millimetre-wave networks

未来的无线高速、宽带无处不在的网络需要复杂的、具有成本效益的天线阵列接收器，以实现业务的快速开发、安装和可重新配置。这样的接收器必须具有独特的特性，如低成本的高集成度，对频段和到达方向的灵活性，自适应能力，并且必须能够消除来自在同一频段运行的其他系统的干扰。广泛应用于较低GHz频率范围的多输入多输出（MIMO）系统、较低毫米波范围的先进超宽带（UWB）地面和卫星通信以及各种频率范围的检测和测距。这个研究项目有几个目标。首先，我们将研究衬底集成波导（SIW）技术中的不同馈电和天线元件场景，该技术为毫米波电路和系统提供了低成本设计平台。其次，我们将开发具有集成放大器的低成本，低噪声直接转换接收器架构的新概念。第三，将考虑焦平面阵列应用于毫米波探测应用。原型制作和实验验证将在研究工作的关键时刻进行。最后阶段将关注系统集成和追求商业上可行的宽带天线阵列接收器。这项研究不仅将帮助我们的工业赞助商通过这项技术抢占竞争市场优势，征服新兴的宽带无处不在的网络，而且还将为加拿大工业提供技术资源和科学人员，以保持在新产品和服务开发中的领先地位。

Future wireless high-speed, broad-bandwidth ubiquitous networks require sophisticated cost-effective antennaarray receivers for the rapid development, installation and re-configurability of services. Such receivers mustpossess unique properties such as being highly integrated at low cost, agile with respect to frequency bands anddirections of arrival, adaptive, and they must be able to cancel interference from other systems operating in thesame frequency bands. Applications are widely found in multiple-input multiple-output (MIMO) systems in thelower GHz frequency range, advanced ultra-wideband (UWB) terrestrial and satellite communications in thelower millimetre-wave range, and detection and ranging at various frequency ranges.Several objectives are targeted in this research project. First, we will investigate different feeding andantenna-element scenarios in substrate-integrated waveguide (SIW) technology, which provides a low-costdesign platform for millimetre-wave circuits and systems. Second, we will develop a new concept for low-cost,low-noise direct-conversion receiver architecture with integrated amplifiers. Third, focal-plane-arrayapplications will be considered for millimetre-wave detection applications. Prototype fabrication andexperimental validation will be pursued at critical points during the research work. The final stage will beconcerned with system integration and the pursuit of a commercially viable broadband antenna array receiver.This research will not only assist our industrial sponsor to seize competitive market advantages through thistechnology for conquering emerging broadband ubiquitous networks, but it will also provide Canadian industrywith the technical resources and scientific personnel to maintain the leading role in the development of newproducts and services.
