PEEC modeling of antenna characteristics

Electromagnetic modeling of antenna characteristics can be performed using different methods. This papers deals with antenna modeling using Partial Element Equivalent Circuit (PEEC) models. Antenna properties including input impedance, radiation diagrams and gain are computed from PEEC model results. The input impedance is computed directly by using the currents and voltages at the feed-point of the antenna. The radiation diagrams are computed in a post-processing step by treating each volume cell as an infinitesimal dipole and using the superposition principle to compute the radiated field. The computed results are compared to analytical results for dipoles. For more complex antenna structures the computed results are compared with measurements and results from other computational methods. Accurate and fast results shows that the method is promising as an antenna system design tool.Godkänd; 2006; 20061114 (ysko
