Application Note: Using Electromagnetic Analysis For RFID Antenna Design

Source: Sonnet Software

The application note demonstrates the use of Sonnet's electromagnetic analysis software to design a 13.56 MHz RFID inductor and a 900 MHz RFID antenna accurately and rapidly. Sonnet’s extreme accuracy is a result of being based on the FFT (Fast Fourier Transform) formulation of the 3D planar Method of Moments (MoM), and Sonnet’s speed is the result of a revolutionary new interpolation (Adaptive Band Synthesis), both to be demonstrated. In addition, Sonnet’s automated features, including parameterization and optimization, allow the designer to evaluate a large number of alternatives in an incredibly short period of time. As the wireless markets consolidate, making the most efficient use of the best CAD tools, including Sonnet for electromagnetic analysis, is key to survival.
