Abstract :
In the present work, the authors consider the limiting case of grated patches in the sense that the microstrip dielectric is air and the quasi-microstrip antenna consists of a linear array of narrow printed strips (or thin cylindrical wires) that are far apart compared to their width (radius). The efficiency of such an antenna should be the upper limit on the efficiency of a true microstrip version. The predicted impedances, current distributions, efficiencies, and far-field patterns of these antennas, as well as measured patterns on an eleven-element antenna around 2 GHz, are presented.<>
