In this paper, smallest scalene triangular microstrip antenna was designed for GSM communication applications using simplex optimization method of miniaturization. The antennas were modeled using microstrip lines, and parameter data for smallest triangular element .The data is extracted from the momentum simulation and combined with the microstrip transmission line. The properties of antennas such as bandwidth, gain, cross polar isolation and the return loss have been simulated. Since the resonant frequency is of these antenna is 900MHz, these antenna is suitable for GSM network.
