Abstract

An accurate integral equation method based on quasi-static relationship (QSR), thin dielectric sheet (TDS) method and high-order hierarchical Legendre (HOHL) basis function is proposed in this paper for fast analysis of microstrip antennas radiation problems. This technique employs the QSR of the current on the parallel plate capacitor to describe the field continuity boundary condition and to embody the tight coupling between the radiation patch, the ground plane and the substrate of microstrip antenna. The frequency offset problem of conventional VSIE can be effectively eliminated. Moreover, combined with the TDS and the HOHL basis function, the proposed model can provide high accuracy in input impedance and far-field performance with faster convergence speed and lower computational cost. Numerical results are presented to show the accuracy and efficiency of the proposed method.
