These pre-configured subcircuits are ready for further analysis and ongoing circuit/system design, replacing ideal components in the feed network with actual trace routing and RF front-end components. Figure 11: AWR Design Environment project containing actual array and feed network subcircuits automatically created by the phased array generator wizard Conclusion This white paper has presented a streamlined design flow within the AWR Design Environment platform to help engineers develop phased array antenna systems, complete with antenna array, feed network, and RF front-end components based on behavioral models, that meet stringent performance, reliability, compactness, and cost requirements. This flow relies on an antenna synthesis capability that enables users to create the individual antenna element and use EM analysis for generation of the individual antenna radiation pattern. The radiation pattern data is then used by the phased array generator wizard to configure the individual antenna radiation pattern and the array and feed network details. These details produce a far-field view of the array and can be used to generate a hierarchical design for further analysis and physical realization leveraging leading RF/microwave design tools from AWR software.
