Analysis of arrays of printed strip dipole antennas

It is well known that dipole antennas are suitable for applications in wireless technology, because they are simple to design and have excellent radiation properties. The analysis of series-fed printed strip dipole antennas gets complicated by the presence of dielectric inhomogeneity. In addition, the strip dipoles are closely spaced and connected through transmission lines that are integral part of the antenna. Therefore, an analysis method that takes into account the presence of dielectric substrate and the effect of connecting lines is presented to accurately design these antennas. In this paper, arrays of printed strip dipoles antennas are analyzed based on moment method in the spectral domain. The double-sided configuration has been selected because it offers several practical advantages.
