✦ Synopsis

The uniform distribution of the basic frequency positions is adopted, and the number of the basic frequencies is set to four. Figure shows the results of the dual-frequency antenna, and Figure shows the results of the broadband antenna. From the figure, it can be found that the results calculated by the matrix interpolation technique show good agreement with the results calculated directly. The calculation times are also recorded. The times of the interpolation calculations are greatly reduced from the direct calculations.

CONCLUSION

The matrix interpolation technique in the calculation of microstrip antenna impedance is proposed in this paper. This technique interpolates both the Z-and V-matrices in the whole frequency band from those at some previously calculated frequencies instead of directly filling them from the integral equation. The positions of the basic frequencies are discussed, and the uniform distribution has the most accurate results. The number of basic frequencies is also analyzed. This technique can greatly reduce the simulation time in wideband analysis. Complex calculation results have demonstrated the capability of this technique.
