Abstract

This paper presents a mathematical model of array of equilateral triangular superconducting microstrips implanted in multilayered substrates. The full-wave method is used to calculate the radiation characteristics of equilateral triangular microstrip antennas. In this method, the electric field integral equation for a current element on a grounded dielectric slab of infinite extent is developed by basis functions. An improved analytical model is presented taking into account anisotropic substrates, superconducting material for the triangular patch and multilayered structure. The swarm particle optimization is used to determine an optimum set of excitation and position of the antenna element that provides a radiation pattern with maximal side lobe level reduction. The computed data are found to be in good agreement with results obtained using other methods.
