“…Though volume basis function can be used, wire basis function gives many advantages for wire antenna problem, such as its simple expression, less unknowns, simple modeling, and fast simulation. Sinusoidal basis function as one of better wire basis and weighting functions for extracting the wire current was well studied by many scholars [2–7].…”

“…As we know, the wire structure with uniform radius has been well studied in [2–6]. In the process of MoM for filling with the self impedance, to avoid the singularity, we can simply choose the source current along the center line, and choose the outline of metal cylinder as the weighting line.…”

“…However, the endpoint charge of one monopole at the discontinuity position of sinusoidal basis function will appear. Different conventional methods give different endpoint charge's consideration for single monopole of the sinusoidal function: In filling with the mutual impedance between two monopoles (two half sinusoidal basis functions), partial endpoint charges are considered in [3]; In [4], both endpoint charge are considered by delta functions; No endpoint charges (or zero) are considered in [5]. The mutual impedance between two monopoles will be different from the different consideration for endpoint charges.…”

In this research letter, a simple asymptotical model is present for analyzing wire antenna with different radius. Method of moments (MoM) based on sinusoidal basis function is used to give the analysis. In the process of using MoM for different radius, if we neglect the monopole along normal axis at the joint part, the different consideration of endpoint charges will make the final results different for conventional methods, and final results are also different with the results from HFSS and measurement results. In view of that, a simple asymptotical model is present to approximately deal with the joint part at the position of different radius. One advantage for the introduction of the present model is that the final results will be the same and independent of conventional methods. The other advantage is that the final results based on the present model have better agreement with HFSS and measurement results. Fabricated loop antennas with different radius are given as practical examples to show the advantages of the present model. © 2012 Wiley Periodicals, Inc.

“…The computation of the reaction terms involves the mutual impedance between two sinusoidal sources, which may be two dipoles, a monopole and a dipole, or two monopoles. These terms are computable using either numerical integration algorithms or available closed form expressions [13,14]. The voltages V (q, m) in (7) and (8) denote the reaction integrals of the driving fields, which are given by…”

Abstract-In the present paper, a combined method of auxiliary sources (MAS)-reaction matching (RM) approach is presented for the analysis of arrays of arbitrarily located cylindrical dipoles. It is shown that the addition of auxiliary monopole terminal sources to each array element results in a superior solution with regard to the numerical stability of the computed quantities, the behavior of the current distributions of the array elements and the resulting errors of the electric field boundary condition. Numerical results are presented for various representative array configurations, in order to illustrate the features of the proposed method and exhibit its advantages over conventional Method of Moments (MoM) schemes, especially in cases of moderately large-scale arrays. Finally, a few concluding remarks are discussed.

Abstract-The analysis of an antenna mutual coupling is a significant issue for designing the wireless communication system especially includesan array mutual coupling problem. The accurate analysis of the mutual coupling between antennas is needed. Accordingly, several methods for the mutual impedance calculation of dipoles have been studied in cases of coplanar-skew and nonplanar-skew. This paper proposes an exact and simple method for analyzing the mutual impedance between two arbitrarily located and slanted dipoles using the modified induced EMF method; their expressions and the exact analytic solution. The proposed formula and their closed-form solutions are verified by numerical solution using HFSS and give good agreement.
