Title: Estimation of directivity on array antennas by using 1D electric current distribution
Abstract: We estimate a radiation pattern of a linear array antenna from 1D electric current distribution by approximating the antenna's radiation directivity by a series of small dipole elements and calculating the sum of radiations from them. As a result, we confirm that the estimation on the dipole array antenna is accurate and good pattern on the patch array antenna is obtained by removing the effect of the edges of the ground plane of the antenna. We also show that estimation results are obtained in high accuracy by setting the sampling interval l ≤ λ/28 on the all antennas under test.
