2015;12(5):1-23]. (ISSN:1097-8135). http://www.lifesciencesite.com.В статье рассмотрена актуальность применения метода моментов в спектральной области. Момент Метод (ММ) используется в спектральной области, где кусочно-синусоидальный базис
функции используются для расширения распределения тока на диполь.Abstract: The Moment Method (MM) is employed in the spectral domain where piece-wise sinusoidal basis functions are used to expand the current distribution on the dipole. The current distribution and input impedance are calculated as functions of the layers parameters. The effects of the material anisotropy and superstrate (cover) parameters are studied. Expressions for the far-zone fields of the dipole in the anisotropic substrate-superstrate structure are derived, and radiation patterns are computed for different structure parameter. Finally, Improvement of Single-Element Antenna Design by using anisotropic layer will be demonstraited.
