Asymptotic Theory for Dipole Radiation in the Presence of a Lossy Slab Lying on a Conducting Half-space
Author: James R. Wait
Publisher:
ISBN:
Category :
Languages : en
Pages : 21
Book Description
The basic theory for dipole radiation in the presence of a two-layer half-space is outlined with special reference to using it as a model for studying radio propagation through and over heavily vegetated terrain. The source dipole may be located above or below the top surface of the slab. The dipole orientation is either vertical or horizontal. The asymptotic derivations for the field expressions are carried out without making the usual assumption that the refraction index of the uppermost layer is large compared with unity. The final results exhibit the expected inverse square dependence of the fields on horizontal range. (Author).

Analysis of Arbitrarily Oriented Thin Wire Antenna Arrays Over Imperfect Ground Planes

ISBN:
Category : Antenna arrays
Languages : en
Pages : 110
Book Description
The work considers the analysis of antenna and arrays of thin wires of arbitrary orientation above imperfectly conducting ground planes. Emphasis is placed on the development of fast and accurate techniques for computation of the characteristics of antenna systems. An important problem is the evaluation of certain semi-infinite integrals encountered in the exact Sommerfeld solution. The time required for computation of these integrals is reduced by the application of interpolatory quadrature formulas. Where applicable, a modified method of steepest descent is used to evaluate the integrals. 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.
