Teaching, Design and Verification Support System for Radio Frequency Passive Components

Abstract

A teaching, design, and verification aid system for radio frequency passive components includes at least one circuit board. The front side of the circuit board comprises at least an impedance matching module, a calibration reference module, an antenna module, and a filter module. The impedance matching module is used for impedance characteristic and mismatch verification operations. The calibration reference module uses open circuits, closed circuits, and open circuits to calibrate a vector network analyzer. The antenna module is used to directly display the receiving range of various antennas. The filter module is used to demonstrate how to filter signals of specific frequencies. The back side of the circuit board comprises at least a Smith chart and an antenna radiation pattern comparison diagram. These Smith charts and antenna radiation pattern comparison diagrams are used to transform complex radio frequency theory into visual comparison tools, allowing users to connect measurement data with physical meaning through real-time comparison. They also provide antenna design assistance and teaching guidance, enabling users to understand complex spatial radiation and impedance concepts without needing to consult books.
