#4963 Dual-Band RF Energy Harvesting (RFEH) Architecture Google Antigravity: TRIZ Workflow App Synthesized Innovation Architectures Primary Architecture Selection : A decoupled dual-channel rectenna architecture utilizing a 3D folded dual-resonant PIFA, integrated low-loss LC diplexer, independent narrowband L-match networks, 3-stage SMS7630 zero-bias Schottky multipliers, passive magnetic cold-start step-up bootstrap, and an event-driven PMIC regulated at 0.48 * V_oc MPPT with sub-25 nA static bias current. Concept : Decoupled Diplexed Dual-Channel Rectenna with Adaptive Self-Biasing Dickson Multiplier First Principles Basis: Bode-Fano matching limits dictate that non-contiguous broadband impedance transformation to a reactive load suffers severe reflection; separating the 902-928 MHz and 2.4 GHz paths via an LC diplexer allows independent, narrowband, high-Q voltage-boosting matching stages (Q matching Chu-Harrington limits for compact ka < 0.5) that feed independent low-barr...
