Analysis of arbitrarily oriented thin wire antenna arrays over imperfect ground planes
Abstract
The development of fast and accurate techniques for computation of the characteristics of antenna systems is considered. An important problem is the evaluation of certain semiinfinite integrals encountered in the exact Sommerfeld solution. The time required for computation of these integrals is reduced by the application of interpolatory quadrature formulas. The approximate reflection coefficient method is derived from the Sommerfeld formulation via the method of steepest descent. The accuracy of the reflection coefficient method relative to the Sommerfeld method is discussed. Finally, formulas convenient for the optimization of various performance indices are discussed. Typical indices that have been optimized, both with and without constraints, are directivity, power gain, quality factor, and main beam radiation efficiency.
