Abstract:
The electrodynamic analysis of arc dipole antenna is based on the solution two-dimensional integro-differential equation. The two-dimensional equation is transformed to one-dimensional hyper-singular equation by means of separation of logarithmic sin-gularity.
The solution of hyper-singular equation is looked for seek with the help of expansion in series by the Chebyshev polynomial-s of second kind with the coefficient which realize Meixner condition-s on a edge.
The matrix elements are presented like double ore triple integrals. The problem of calculation of matrix elements is solved.
The computer-based program is worked up and the numerical calculation is realized.
The convergence of numerical analytic method is investigated. The investigations of dependence from the antennas parameters are kept.
