项目摘要

Circularly polarized antennas have been applied in many wireless applications such as GPS due to their abilityto mitigate the multipath effects and providing the freedom of orientations. However, many issues need to beaddressed for mass deployment in low-cost IoT devices and, in particular, for autonomous vehicles.Metallic choke ring ground planes are traditionally used along with GNSS antennas to avoid or minimize thereception of multipath signals. However, their large size, heavyweight, and costly fabrication have always beena problem. We will develop a multi-band compact substrate integrated choke ring ground structure using anovel idea of folded corrugations to address these challenges.Optically transparent antennas can be integrated on various surfaces with minimal effect on their appearances.An important application of these antennas is on the windshield for the car's radio and GPS purposes.Transparent conductors' applications are limited due to their high cost, high electrical resistivity, andchallenging manufacturing methods. In this theme, novel transparent GPS antennas will be designed andimplemented based on new structures and additive manufacturing methods.The Partner, NovAtel Inc, currently produces precise positioning systems but needs significant advances inLow-profile antennas to fully support emerging automotive applications. NovAtel will take research results toinfluence future generations of positioning and autonomous instruments, ideally from Canadian companies.NovAtel plans to use the developed low-profile antennas to empower its current solutions for precisionagriculture, defence, transportation, marine, and survey.

圆形极化天线已在许多无线应用中应用于GPS，因为它们能够减轻多径效应并提供方向自由。但是，许多问题需要在低成本的物联网设备，尤其是自动驾驶汽车中进行大规模部署。传统上与GNSS天线一起使用，以避免或最大程度地减少多径信号的影响。但是，它们的大尺寸，重量级和昂贵的制造一直是问题。我们将使用折叠式波纹的主态思路来开发多束型紧凑的底物集成挡块地面结构，以应对这些挑战。可以将透明的天线整合在各种表面上，并且对其外观的最小效果，这些天线的重要应用是在挡风玻璃上的高频道上的高频率，其较高的电源是他们的高频道。制造方法。在这个主题中，新颖的透明GPS天线将根据新结构和添加剂制造方法进行设计和实施。合作伙伴Novatel Inc，目前会生成精确的定位系统，但需要重大进步，以充分支持新兴的自动化应用。 Novatel将获得研究结果，从而使后代的定位和自主工具，理想情况下是加拿大公司的。Novatel计划使用发达的低调天线来授权其当前的解决方案用于精密性，国防，运输，海洋和调查。
