Transmission Line Model to Characterize Microstrip Antennas Capped with Dielectric Superstrates
The transmission line model in conjunction with the reciprocity theorem is used to compute the radiation field of a microstrip patch antenna covered with a dielectric superstrate and to investigate the effect of the superstrate on improving the directivity and radiation pattern of the printed patch antenna. The cavity model is used to replace the patch antenna by two magnetic line sources embedded in the multilayer structure. The proposed analytical formulation for the antennas far-field is verified by a comparison with numerical full-wave simulations. A good agreement is observed. The analytical formulation introduced here can be extended for the case of a patch antenna embedded in a multilayered artificial dielectric structure.
