A trial investigation of circular microstrip patch antenna on three unique substrates, FR4 with a permittivity of 4.4, RT Duroid with a permittivity of 2.2 and Taconic substrate with a permittivity of 3.2 is presented. The measured outcomes for S11, resonant frequencies, radiation efficiency and radiation pattern for the planned design of patch antenna with openings in the ground plane are given. The total dimension of the proposed antennas is 30×30×1.6〖mm〗^3. the point of this survey paper is to think about and display a reasonable substrate for microstrip patch antenna which can deliver great radiation efficiency, gain, return loss and better radiation pattern alongside the multiband activity.
