关于客户
RF2B 是一家无线设计服务公司，提供跨各种空中接口和频段的定制天线设计和验证服务。该公司的使命是为射频集成电路开发商、制造商和卫星系统提供商提高质量并缩短上市时间。 RF2B 提供基于颠覆性系统级方法的验证服务以及应用参考射频集成电路设计的交钥匙开发。使用快速、准确的模拟是其效率的关键。该公司的客户应用涵盖移动、医疗、跟踪器、网关、家庭自动化和游戏配件。
挑战
RF2B 的任务是为其客户 Menlo Micro（高性能 RF MEMS 开关集成电路开发商）开发适用于 3.5GHz 小型蜂窝公民宽带无线电服务 (CBRS) 基站的相控阵天线概念设计验证。面临的挑战是实现足够的方位角和仰角波束转向范围、足够的栅瓣抑制和更高的效率。这需要进行高级设计分析来确定天线阵列的列数和行数、元件类型、元件间距、角步长和幅度锥度。另一个挑战是设计的整体复杂性，需要高效的天线阵列仿真和包括馈电网络的设计方法。天线阵列还需要优化其机械环境，包括外壳和天线罩。
解决方案
Altair Feko 用于解决这些挑战。它具有称为有限阵列分析的功能，以及合成天线阵列的内置脚本。这些功能显着加快了高级权衡分析的速度，因为模型构建加速和内存消耗更低，从而缩短了仿真时间，这在高级设计阶段至关重要。在早期阶段，各个模块使用多端口 S 参数进行建模，这些参数很好地集成到 Feko 非辐射网络原理图功能中。通过 Feko 分析对添加天线外壳（尤其是天线罩）时使用的材料和天线阵列的分离进行仔细的权衡分析，使得优化天线阵列设计成为可能。

Intelligent Building Automation System and Energy Saving Solution
One of the most difficult problems facing the world is conserving energy in buildings. However, it is not easy to have a cost-effective solution to reduce energy usage in a building. One solution for saving energy is to implement an intelligent building automation system (BAS) which can be controlled according to its schedule. In Indonesia a large university with a five floor building and 22 classrooms wanted to save the amount of energy being used.
