Author(s) : SHASHANK GUPTA   


An optimization technique of Resonant Frequency for co-axial probe feed microstrip patch antenna using Differential Evolution (DE) Optimization Algorithm is presented in this paper. The DE program for optimization of resonant frequency is developed and executed in C language and finally the optimized antenna parameters are simulated in Zeeland IE3D software. The superiority of convergence in DE algorithm over other optimization technique is also shown in this paper. “3dplotter.swf”-software is used for graphical representation of different optimized geometrical parameters of the patch antenna. Co-axial probe feed rectangular microstrip antenna is a popular type of microstrip patch antenna and has applications in communication and radar system. Differential Evolution (DE) optimization is also a popular optimization algorithm and recently it is used for design optimization of microstrip patch antennas. The investigation is made at different microwave frequencies ranging between 3 GHz to 10 GHz. The optimization problem has three variables namely patch length and width and the position of feed. Accuracy of the results encourages use of DE.
