A versatile Integrated Design System for designing printed- circuit antennas and RF sensors will be developed. The unique features of this system are an Element Design module for designing passive as well as active antennas, a Feed Network Design module for designing layouts, and an object- oriented circuit analysis capability for layout verification. The Element Design module will be equipped with an accurate numerical simulator for modeling structures on multi-layer, complex substrates with vertical loads for active device insertion. The graphical user interface for this module will have a simple geometry specification process with editing capabilities for sensitivity analysis and auto and manual gridding capabilities for simulation purposes. The Array/Feed Network design module will be equipped with a set of icons defined either by the user or the design system for constructing layouts. These icons will represent various array and circuit elements to be used in the layout design. Construction of feed networks will be done by clicking and connecting the different icons sequentially. Connection algorithms will be developed to update the scattering parameters of any two connected icons as the layout is being constructed. With these built-in connection algorithms, this object-oriented construction approach will provide a designer with a practical means to explore new designs as well as assess design tradeoffs. It will allow a designer to adopt a design methodology for different design requirements and help designers achieve a single-pass design.

将开发用于设计印刷电路天线和射频传感器的多功能集成设计系统。 该系统的独特功能包括用于设计无源和有源天线的元件设计模块、用于设计布局的馈电网络设计模块以及用于布局验证的面向对象的电路分析功能。 元件设计模块将配备精确的数值模拟器，用于对多层复杂基板上的结构进行建模，并具有用于有源器件插入的垂直载荷。 该模块的图形用户界面将具有简单的几何规范过程，具有用于灵敏度分析的编辑功能以及用于模拟目的的自动和手动网格化功能。 阵列/馈送网络设计模块将配备一组由用户或设计系统定义的图标，用于构建布局。 这些图标将代表布局设计中使用的各种阵列和电路元件。 馈送网络的构建将通过依次单击并连接不同的图标来完成。 将开发连接算法来在构建布局时更新任意两个连接图标的散射参数。 借助这些内置的连接算法，这种面向对象的构造方法将为设计人员提供探索新设计以及评估设计权衡的实用方法。 它将允许设计人员针对不同的设计要求采用设计方法，并帮助设计人员实现单通道设计。
