In this paper the effect of dielectric cover (also called superstrate) which influence on the main characteristics of rectangular microstrip antenna is presented. The antenna main characteristics are including the resonant frequency, gain, bandwidth, beam width, radiation patterns, VSWR and return loss is investigated with and without dielectric superstrate. The antenna is designed at the center frequency of 2.4GHz and simulated using Ansoft electromagnetic simulator named as High Frequency Structure Simulator. When the dielectric superstrate is touching the patch antenna, the resonant frequency is reduced and also which effects on other parameters slightly change their performance. The comparative analysis of the rectangular microstrip patch antenna (RMPA) characteristics with and without it is carried out.
