Abstract: In this paper, two slotted Microstrip patch antennas, one is circular slotted and other is rectangular slotted antenna, has been studied and their equivalent circuit modeling has been done. The equivalent circuit modeling has been carried out using RF toolbox of MATLAB. In this, series RLC resonant circuit is used to get the desired S11 response for the both the proposed antennas. The equivalent model for both the antennas consists of four series band pass filters in a parallel combination with different values of R, L and C.
