T/R Module Performance Bounds Using Pareto Front Matching

The patent applies partial action by designing matching circuits that achieve sufficient but not excessive isolation levels. Instead of pursuing complete isolation which would cause excessive insertion loss, the method identifies optimal points on the Pareto front where isolation is improved to a practical degree while accepting minimal insertion loss penalty. This resolves the contradiction by finding the sweet spot where further isolation improvement would not provide practical benefit but would significantly increase loss.

The patent utilizes parameter changes by systematically varying matching circuit component values and configurations to map out the tradeoff surface between isolation and insertion loss. By changing circuit parameters and measuring performance across the Pareto front, the method identifies optimal operating points that balance both competing requirements, resolving the contradiction through quantitative parameter optimization.

The patent applies preliminary action by pre-characterizing the T/R module and antenna system to establish the Pareto front before final matching circuit design. By performing initial measurements and calculations to map the tradeoff surface, the method eliminates the need for extensive trial-and-error experimentation later in the design process. This preliminary characterization resolves the contradiction by providing a roadmap for optimal design that avoids time-consuming iterative experiments.

The patent uses copying by creating a mathematical model of the T/R module and antenna system that replicates their electromagnetic behavior. This model allows virtual experimentation and optimization without physical prototyping, significantly reducing design time while maintaining accuracy. The model copies the essential characteristics of the physical system, enabling rapid exploration of matching circuit options without repeated physical measurements.
