Title    The analysis of radiation of the microstrip antenna base on  volume surface integral equation
Abstract
Microstrip antenna is an antenna technology through printing technology based on microwave substrates since 1950s.It is perfect for the advantages of small volume, light weight, low profile and easily integration, so it is widely used in several areas: satellite communication, ground location, animal prediction and medical diagnosis. In this paper, the volume surface integral equation is used to analyze the radiation characteristics of microstrip antenna，and introduces the basic parameters in the process of calculation, some definitions of these parameters and solutions. Microstrip feed, MOM, transmission line model are demonstrated by some examples. The paper also introduces the calculation procedure, the formulations of volume surface integral equations, the RWG basis function is used to expand the surface current density and SWG basis functions to expand the dielectric flux density, the Galerkin’s method is chosen as weight function to calculate the equation. Finally, two rectangular patch antennas will be chosen as examples, using the HFSS simulation, and compared with the results obtained by the VSIE to obtain a final conclusion.
