Design and Development of a Low Profile, Multi-band GNSS Antenna

集成天线解决方案，SELEX ES提出了一种天线概念，该概念使用新的微带技术，从单一输出、低轮廓贴片天线获得多频率、GNSS操作。基本设计是一种四频圆形贴片天线，具有3个寄生同心环。这项技术使用成熟的印刷电路制造技术，因此建议的解决方案可以很容易地制造，并且成本较低，以适应尺寸和重量是关键参数的广泛应用，例如，拆卸的士兵或小型车辆。通过应用模块化的“单元”方法，天线可根据应用和安装的平台进行扩展。所有这些设计的关键驱动因素是天线本身在平台上的最佳性能、系统中所需的天线元件数量最小化、模块化、低生命周期成本以及低尺寸、重量和功率(交换)。一旦通过了最初的概念分析和模拟阶段，快速现场原型提供了对物理解决方案的快速洞察。我们的设计和测量设施包括一个安全、大型的室外天线测试范围，以及转台和车间。SELEX ES还拥有先进的平台分析工具，利用大型、安全的计算资源和先进的计算机分析进行3D电磁模拟。通过基于英国的大型LIST-X天线制造能力，确保了天线的供应；SELEX ES已设计和制造了超过40,000个天线。这包括英国(和意大利)所有军用车辆和背包ECM天线的90%以上，快速喷气式飞机的共形天线，国防、科学和技术实验室(DSTL)、英国国防部(MoD)和其他政府部门(OGD)的人体佩戴天线，国际无人机(UAV)的共形天线，隐蔽车辆天线和大型国防优质控制辐射方向图天线(CRPA)。

Integrated Antenna Solutions, Selex ES are proposing an antenna concept that uses novel microstrip technology to obtain multi frequency, GNSS operation from a single output, low profile patch antenna. The fundamental design is a quad-band circular patch antenna that has 3 parasitic concentric rings. This technology uses established printed circuit fabrication techniques and the proposed solution can therefore be easily manufactured, and at low cost, to suit a wide range of applications where size and weight is a key parameter, for example, the dismounted soldier or small vehicle. By applying a modular "unit cell" approach the antenna is scalable accoriding to the application and installed platform.The key drivers for all these designs are optimum performance of the antenna on the platform itself, minimisation of the number of antenna elements required in the system, modularity, low through life costs and low Size, Weight and Power (SWaP). Rapid on-site prototyping provides fast insight into the physical solution once the initial concept analysis and simulation stages have been passed. Our design and measurement facilities include a secure, large, outdoor antenna test range with a turntable and workshop. Selex ES also possesses advanced platform analysis tools using large, secure computing resources and advanced computer analysis for 3D electromagnetic simulation.Assured supply of antennas is achieved with a large, UK based, List-X antenna manufacturing capability; Selex ES have designed and manufactured over 40,000 antennas. This includes over 90% of all the UK (and Italian) military vehicle and manpack ECM antennas, conformal antennas for fast jets, body-worn antennas for the Defence , Science and Technology Laboratory (Dstl), the UK Ministry of Defence (MoD) and other government departments (OGDs), conformal antennas for international Unmanned Air Vehicles (UAVs), covert vehicle antennas and Control Radiation Pattern Antennas (CRPA) for a large defence prime.
