Analysis Of MPIE-MOM Consumption Of Half Space Antenna

An ideal analysis of antennas is often assumed that antennas are locatedinfinite free space.However, because of ground existences,the ground influencemust be considered if the antenna is near the ground.With the study of solving theMixed Potential Electric Field Integral Equation of electromagnetic radiation andscattering in multilayer medium,this thesis deduces specific solutions for two layermedium both end point and the source point is in the air layer function. Then thenumerical evaluation method of Sommerfeld Integrals appeared in the expressionsis discussed，also put forward a method of improving2D–DCIM for calculating theGreen function of lossy plane layered medium.Then using the method of DCIM andthe Sommerfeld integral,deducing the vector potentials of vertical and horizontaldipoles near an interface. Finally, applying the sinusoidal galerkin methods,theradiation characteristic and the radiation field of the vertical and horizontalantennas above lossy ground are analyzed by the method of moments，calculate theresults by the Matlab software, Also According to the result of calculation toSimulate the vertical radiation pattern and horizontal radiation pattern,andAccording to the analysis with the variation of conductivity, dielectricconstant,changes of medium properties of metals, loss characteristics.TheMPIE-MOM method used in this research in the near-surface antenna is not onlyhigh precision, and the more general.
