The major limitations of MSAs are their narrow impedance, axial ratio(AR), bandwidth, small gain and lower power handling capacity. Here the overview of air fed high gain patch antenna is presented. Various gain enhancement methods like microstrip antenna array ,superstrate structure, change in dielectric material and partial removal of substrate will be studied and the review is presented. Air is used as dielectric medium between feed patch and ground plane.
